 # NormalJS ORM - AI Coding Agent Instructions
 
+## Quick Start Template
+
+When creating a new NormalJS project, **always start with this pattern**:
+
+```javascript
+const { Connection, Repository } = require('normaljs');
+
+// 1. Create connection (choose your database)
+const conn = new Connection({
+  client: 'sqlite3', // or 'pg' for PostgreSQL, 'mysql', 'mssql'
+  connection: { filename: ':memory:' } // or real DB config
+});
+
+// 2. Create repository (connection managed automatically)
+const repo = new Repository(conn);
+
+// 3. Define models as ES6 classes
+class Users {
+  static _name = 'Users'; // REQUIRED: Registry key
+  static table = 'users'; // Optional: defaults to snake_case of _name
+  static fields = {
+    id: 'primary', // Shorthand for auto-increment primary key
+    email: { type: 'string', unique: true, required: true },
+    active: { type: 'boolean', default: true },
+  };
+  
+  // Instance methods work on active records
+  get domain() {
+    return this.email?.split('@')[1];
+  }
+  
+  // Static methods for custom queries (scopes)
+  static activeUsers() {
+    return this.where({ active: true });
+  }
+}
+
+// 4. Register models
+repo.register(Users);
+
+// 5. Sync schema (development only!)
+await repo.sync();
+
+// 6. Use models via repository
+const UsersModel = repo.get('Users');
+const user = await UsersModel.create({ email: 'test@example.com' });
+```
+
+## ✅ DO / ❌ DON'T Checklist
+
+**When defining models:**
+
+✅ **DO:**
+- Always include `static _name` (required for registration)
+- Use `static fields` object for schema definition
+- Add instance methods/getters directly on the class
+- Add static methods for custom query scopes
+- Use descriptive PascalCase names for models (`Users`, `BlogPosts`)
+
+❌ **DON'T:**
+- Never instantiate models with `new Users()` directly
+- Don't forget `static _name` (causes registration errors)
+- Don't use async getters (use methods instead)
+- Don't define fields outside the `static fields` object
+
+**When working with relations:**
+
+✅ **DO:**
+```javascript
+// Define relations as fields
+class Posts {
+  static fields = {
+    author_id: { type: 'many-to-one', model: 'Users' }, // Creates FK column
+    comments: { type: 'one-to-many', foreign: 'Comments.post_id' },
+    tags: { type: 'many-to-many', model: 'Tags' }
+  };
+}
+
+// Load relations explicitly
+const post = await Posts.findById(1);
+await post.comments.load();
+await post.tags.load();
+
+// Use include for eager loading
+const post = await Posts.where({ id: 1 }).include('author', 'tags').first();
+```
+
+❌ **DON'T:**
+```javascript
+// Don't try to access unloaded relations
+const post = await Posts.findById(1);
+console.log(post.comments); // May be undefined if not loaded!
+
+// Don't manually join tables for relations
+const query = Posts.query().join('users', 'posts.author_id', 'users.id'); // Use include instead!
+```
+
+**When querying:**
+
+✅ **DO:**
+```javascript
+// Access models via repository
+const Users = repo.get('Users');
+
+// Use method chaining
+const users = await Users.where({ active: true }).limit(10).orderBy('created_at', 'desc').find();
+
+// Use findById for single records
+const user = await Users.findById(1);
+
+// Use first() for single results
+const user = await Users.where({ email }).first();
+
+// Use transactions for writes
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  await Users.create({ email: 'test@example.com' });
+});
+```
+
+❌ **DON'T:**
+```javascript
+// Don't query without going through repository
+const users = await Users.query().find(); // Users is the class, not the model!
+
+// Don't mix transaction contexts
+await repo.transaction(async tx => {
+  await repo.get('Users').create({ email }); // Wrong! Use tx.get('Users')
+});
+
+// Don't use .sync({ force: true }) in production
+await repo.sync({ force: true }); // ONLY for development/testing
+```
+
+**When handling records:**
+
+✅ **DO:**
+```javascript
+// Method 1: Direct modification (optimal - persists automatically)
+const user = await Users.findById(1);
+user.email = 'new@example.com';
+user.updated_at = new Date();
+// Changes persist automatically on next query or transaction flush
+
+// Method 2: write() with key/value pairs (immediate flush)
+const user = await Users.findById(1);
+await user.write({ email: 'new@example.com', updated_at: new Date() });
+
+// Delete records
+await user.unlink();
+
+// Check for null/undefined
+const user = await Users.where({ email }).first();
+if (!user) {
+  throw new Error('User not found');
+}
+```
+
+❌ **DON'T:**
+```javascript
+// Don't use update() method
+await user.update({ email: 'new@example.com' }); // Method doesn't exist!
+
+// Don't set properties then call write() without arguments
+user.email = 'new@example.com';
+await user.write(); // Anti-pattern! Use write({ email: ... }) instead
+
+// Don't use save() method
+await user.save(); // Doesn't exist!
+
+// Don't use delete() method
+await user.delete(); // Use unlink() instead
+```
+
+❌ **DON'T:**
+```javascript
+// Don't use update() method
+await user.update({ email: 'new@example.com' }); // Method doesn't exist!
+
+// Don't use save() method
+await user.save(); // Doesn't exist!
+
+// Don't use delete() method
+await user.delete(); // Use unlink() instead
+```
+
 ## Architecture Overview
 
 NormalJS is a full-featured Node.js ORM with active record patterns, built on Knex.js. Core components:
 
-- **Repository**: Model registry and transaction coordinator (`src/Repository.js`)
-- **Model**: Query builder and schema management (`src/Model.js`)
-- **Record**: Active record instances with lazy field access (`src/Record.js`)
-- **Connection**: Knex wrapper supporting PostgreSQL/SQLite (`src/Connection.js`)
-- **Fields**: Type system with schema inference (`src/Fields.js`, `src/fields/`)
+- **Repository**: Model registry and transaction coordinator
+- **Model**: Query builder with fluent API, returns active records
+- **Record**: Active record instances with lazy field access
+- **Connection**: Knex wrapper supporting PostgreSQL/SQLite/MySQL
+- **Fields**: Type system with validation, serialization, and relations
+
+## Field Type Reference
+
+```javascript
+static fields = {
+  // Primary key (shorthand)
+  id: 'primary', // → { type: 'number', primary: true, generated: true }
+  
+  // Basic types (shorthand)
+  name: 'string',        // → { type: 'string' }
+  age: 'integer',        // → { type: 'integer' }
+  price: 'float',        // → { type: 'float' }
+  active: 'boolean',     // → { type: 'boolean' }
+  bio: 'text',           // → { type: 'text' }
+  
+  // Full definitions with constraints
+  email: { type: 'string', unique: true, required: true, size: 255 },
+  count: { type: 'integer', default: 0, index: true },
+  score: { type: 'float', precision: 2 },
+  metadata: { type: 'json' },
+  created_at: { type: 'datetime', default: () => new Date() },
+  status: { type: 'enum', values: ['draft', 'published', 'archived'] },
+  
+  // Relations (create foreign key)
+  author_id: { type: 'many-to-one', model: 'Users', cascade: true },
+  
+  // Relations (virtual - no column)
+  posts: { type: 'one-to-many', foreign: 'Posts.author_id' },
+  tags: { type: 'many-to-many', model: 'Tags', joinTable: 'posts_tags' }
+}
+```
 
-## Coding patterns
+## Relation Patterns
 
-- Use SRP (Single Responsibility Principle) to keep models focused and manageable.
-- DRY (Don't Repeat Yourself): Abstract common logic into base classes or utility functions.
-- Avoid too high complexity in methods, favoring smaller, testable functions.
-- Each method should have a clear purpose and single responsibility.
-- Document with jsdoc annotations for functions and classes.
-- Update tests during code changes to ensure coverage and correctness.
-- We target at least 80% test coverage across the codebase
+**Many-to-One** (belongs to - creates FK column):
+```javascript
+class Posts {
+  static fields = {
+    id: 'primary',
+    author_id: { type: 'many-to-one', model: 'Users' }, // Creates author_id column
+  };
+}
 
-## Model Definition Patterns
+// Usage
+const post = await Posts.findById(1);
+const author = await post.author.load(); // Loads related user
 
-Models are ES6 classes with static metadata:
+// Change relation - Method 1: Direct modification
+post.author_id = newUserId;
+// Persists automatically
 
+// Change relation - Method 2: write() with key/value pairs
+await post.write({ author_id: newUserId });
+```
+
+**One-to-Many** (has many - virtual field):
 ```javascript
 class Users {
-  static _name = 'Users'; // Registry key (required)
-  static table = 'users'; // DB table name (optional, inferred from name)
   static fields = {
-    id: 'primary', // Shorthand for { type: "number", primary: true, generated: true }
-    email: { type: 'string', unique: true, required: true },
-    posts: { type: 'one-to-many', foreign: 'Posts.author_id' }, // Relations
-    tags: { type: 'many-to-many', model: 'Tags' }, // Auto-creates join table
+    id: 'primary',
+    posts: { type: 'one-to-many', foreign: 'Posts.author_id' }, // No column created
   };
+}
 
-  // Instance methods/getters work on active records
-  get name() {
-    return `${this.firstname} ${this.lastname}`;
-  }
+// Usage
+const user = await Users.findById(1);
+await user.posts.load(); // Loads all posts where author_id = user.id
+const posts = user.posts.items; // Access loaded collection
+```
+
+**Many-to-Many** (auto-creates join table):
+```javascript
+class Posts {
+  static fields = {
+    id: 'primary',
+    tags: { type: 'many-to-many', model: 'Tags' }, // Creates rel_posts_tags table
+  };
 }
+
+class Tags {
+  static fields = {
+    id: 'primary',
+    posts: { type: 'many-to-many', model: 'Posts' }, // Same join table
+  };
+}
+
+// Usage
+const post = await Posts.findById(1);
+await post.tags.load();
+await post.tags.add(tagId); // Add relation
+await post.tags.remove(tagId); // Remove relation
+await post.tags.set([id1, id2, id3]); // Replace all relations
 ```
 
-## Relation Patterns
+## Query Patterns & Best Practices
+
+```javascript
+const Users = repo.get('Users');
+
+// ✅ Find by ID (uses cache when enabled)
+const user = await Users.findById(1);
+
+// ✅ Find one by condition
+const user = await Users.where({ email: 'test@example.com' }).first();
+
+// ✅ Find many with filters
+const users = await Users
+  .where({ active: true })
+  .where('created_at', '>', new Date('2024-01-01'))
+  .orderBy('created_at', 'desc')
+  .limit(10)
+  .find();
+
+// ✅ Complex JSON criteria
+const users = await Users.where({
+  and: [
+    ['active', '=', true],
+    ['age', '>', 18],
+    { or: [['role', '=', 'admin'], ['role', '=', 'moderator']] }
+  ]
+}).find();
+
+// ✅ Eager loading relations
+const users = await Users
+  .where({ active: true })
+  .include('posts', 'profile')
+  .find();
+
+// ✅ Count records
+const count = await Users.where({ active: true }).count();
+
+// ✅ Request-level caching (60 seconds)
+const users = await Users.where({ active: true }).cache(60).find();
+
+// ✅ Create with relations
+const post = await Posts.create({
+  title: 'Hello World',
+  content: 'Post content',
+  author_id: userId,
+  tags: [tagId1, tagId2] // Automatically creates many-to-many relations
+});
+
+// ✅ Update records - Method 1: Direct modification
+const user = await Users.findById(1);
+user.email = 'new@example.com';
+user.updated_at = new Date();
+// Persists automatically on next query or transaction flush
+
+// ✅ Update records - Method 2: write() with key/value pairs (immediate)
+await user.write({ email: 'new@example.com', updated_at: new Date() });
+
+// ✅ Delete records
+await user.unlink();
+```
 
-- **One-to-Many**: `{ type: "one-to-many", foreign: "ChildModel.fk_column" }`
-- **Many-to-One**: `{ type: "many-to-one", model: "ParentModel" }` (creates FK column)
-- **Many-to-Many**: Both sides use `{ type: "many-to-many", model: "OtherModel" }` (auto-creates join table)
+## Transaction Patterns
+
+**Always use transactions for multi-step operations:**
+
+```javascript
+// ✅ Correct: Transaction-scoped repository
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Posts = tx.get('Posts');
+  
+  const user = await Users.create({ email: 'author@example.com' });
+  const post = await Posts.create({
+    title: 'First Post',
+    author_id: user.id
+  });
+  
+  await post.tags.add(tagId);
+  
+  // Commits automatically on success, rolls back on error
+});
+
+// ❌ Wrong: Mixing contexts
+await repo.transaction(async tx => {
+  const user = await repo.get('Users').create({ email }); // Uses wrong context!
+  const post = await tx.get('Posts').create({ title, author_id: user.id });
+});
+```
 
 ## Model Extension System
 
 Register multiple classes with the same `static _name` to extend models:
 
 ```javascript
-// Base model
-class Users { static _name = "Users"; static fields = { id: "primary" }; }
+// Base model (required fields)
+class Users {
+  static _name = 'Users';
+  static fields = {
+    id: 'primary',
+    email: { type: 'string', required: true }
+  };
+}
 
-// Extension (adds fields + methods)
-class Users { static _name = "Users"; static fields = { picture: "string" }; get profileUrl() {...} }
+// Extension (adds features without modifying base)
+class Users {
+  static _name = 'Users'; // Same name merges!
+  static fields = {
+    picture: 'string', // Additional fields
+    profile_url: 'string'
+  };
+  
+  get hasProfile() { // Additional methods
+    return !!this.profile_url;
+  }
+  
+  static verified() { // Additional scopes
+    return this.where({ verified: true });
+  }
+}
 
-repo.register(BaseUsers);
-repo.register(ExtendedUsers);  // Merged into single model
+repo.register(Users); // Register base
+repo.register(Users); // Register extension - merges into one model
 ```

+# Documentation Corrections - Direct Property Modification
+
+## Critical Fix Applied
+
+The documentation has been corrected to show the **proper NormalJS pattern**: direct property modification.
+
+## What Was Wrong
+
+❌ **Incorrect (shown before):**
+```js
+const user = await Users.findById(1);
+await user.update({ email: 'new@example.com' }); // update() doesn't exist!
+```
+
+## What Is Correct
+
+✅ **Correct (optimal NormalJS way):**
+```js
+const user = await Users.findById(1);
+user.email = 'new@example.com'; // Direct modification
+// Changes persist automatically on next query or transaction flush
+
+// Or force immediate write:
+await user.write();
+```
+
+## How NormalJS Active Records Work
+
+1. **Direct Property Modification** (Optimal)
+   - Modify properties directly: `record.field = newValue`
+   - Changes are tracked automatically
+   - Persist on next query or when transaction flushes
+   - This is the most efficient way
+
+2. **Manual Persistence** (When Needed)
+   - Use `await record.write()` to force immediate persistence
+   - No `update()` method exists
+   - No `save()` method exists
+
+3. **Deletion**
+   - Use `await record.unlink()` to delete
+   - No `delete()` method exists
+
+## Files Corrected
+
+### 1. `.github/copilot-instructions.md`
+- ✅ Fixed "When handling records" section
+- ✅ Fixed "Query Patterns" section
+- ✅ Removed all incorrect `update()` examples
+- ✅ Added correct direct modification patterns
+- ✅ Documented `write()` method for manual persistence
+
+### 2. `docs/index.md`
+- ✅ Fixed "Complete Working Example" (step 9)
+- ✅ Fixed "How to: Update and Delete" section
+- ✅ Fixed "How to: Use Transactions" section
+- ✅ Removed all `update()` calls
+- ✅ Shows direct property modification throughout
+
+### 3. `docs/cookbook.md`
+- ✅ Fixed "Update Records" section in CRUD Operations
+- ✅ Fixed transaction examples (inventory deduction, order totals)
+- ✅ Fixed authentication `setPassword()` method
+- ✅ Fixed timestamps example
+- ✅ Fixed soft delete methods (`softDelete()` and `restore()`)
+- ✅ Fixed slug generation `post_create()` hook
+- ✅ Fixed search `post_update()` hook
+- ✅ All examples now use direct modification
+
+### 4. `docs/models.md`
+- ✅ Fixed "Update Records" section
+- ✅ Fixed many-to-one relation usage
+- ✅ Shows ❌ DON'T use `update()` explicitly
+- ✅ Shows ✅ DO use direct modification
+
+## Key Patterns Documented
+
+### Pattern 1: Simple Update
+```js
+const user = await Users.findById(1);
+user.email = 'new@example.com';
+user.name = 'New Name';
+// Persists automatically
+```
+
+### Pattern 2: Update with Immediate Write
+```js
+const user = await Users.findById(1);
+user.email = 'new@example.com';
+await user.write(); // Force immediate persistence
+```
+
+### Pattern 3: Update in Transaction
+```js
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const user = await Users.findById(1);
+  
+  user.email = 'new@example.com';
+  user.updated_at = new Date();
+  // Persists on transaction commit
+});
+```
+
+### Pattern 4: Update with Validation
+```js
+const user = await Users.findById(1);
+if (user.role !== 'admin') {
+  user.email = newEmail;
+  await user.write();
+}
+```
+
+## Anti-Patterns Now Documented
+
+The documentation now explicitly shows what **NOT** to do:
+
+❌ `await user.update({ ... })` - Method doesn't exist
+❌ `await user.save()` - Method doesn't exist  
+❌ `await user.delete()` - Use `unlink()` instead
+❌ Thinking changes won't persist - They do!
+
+## Build Status
+
+✅ Documentation builds successfully
+✅ All examples corrected
+✅ Consistent patterns throughout
+✅ AI agents will now learn the correct NormalJS way
+
+## For AI Coding Agents
+
+When working with NormalJS records:
+
+1. **Always modify properties directly** - This is the optimal pattern
+2. **Changes persist automatically** - On next query or transaction flush
+3. **Use `write()` for immediate persistence** - Only when you need it right away
+4. **No `update()` method exists** - Don't look for it
+5. **No `save()` method exists** - Direct modification handles it

+
+Example from models.md:
+```js
+// ❌ DON'T: Create without transaction for multi-step ops
+const user = await Users.create({ email });
+const profile = await Profiles.create({ user_id: user.id }); // Not atomic!
+
+// ✅ DO: Use transactions
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Profiles = tx.get('Profiles');
+  
+  const user = await Users.create({ email });
+  await Profiles.create({ user_id: user.id });
+});
+```
+
+### 3. ✅ Complete Runnable Code
+
+**Before:** Code snippets with placeholders

+3. **Progressive Complexity:** Simple examples first, then more complex scenarios
+
+4. **Pattern Recognition:** Consistent structure (✅ DO / ❌ DON'T) helps agents learn faster
+
+5. **Cross-References:** Links between related concepts help agents navigate
+
+6. **Keywords:** Rich metadata for semantic search and discovery
+
+## Usage for AI Agents
+
+When an AI coding agent works with NormalJS:
+
+1. **Starting a new project:** Refer to `.github/copilot-instructions.md` → Quick Start Template
+
+2. **Implementing a feature:** Check `docs/cookbook.md` for the specific recipe
+
+3. **Understanding concepts:** Read `docs/models.md` or relevant core concept doc
+
+4. **Avoiding mistakes:** Look for ❌ DON'T patterns in examples
+
+5. **Migrating from Sequelize:** Use `docs/adoption-sequelize.md`
+
+## Build Status

+
+## Error Handling
+
+Common errors and how to handle them.
+
+### Model Not Found
+
+```js
+try {
+  const Users = repo.get('Users');
+} catch (err) {
+  console.error('Model not registered:', err.message);
+}
+```
+
+### Record Not Found
+
+```js
+const user = await Users.findById(999);
+if (!user) {
+  throw new Error('User not found');
+}
+```
+
+### Validation Errors
+
+```js
+try {
+  const user = await Users.create({ name: 'John' }); // Missing required 'email'
+} catch (err) {
+  console.error('Validation failed:', err.message);
+}
+```
+
+### Transaction Errors
+
+```js
+try {
+  await repo.transaction(async tx => {
+    const Users = tx.get('Users');
+    await Users.create({ email: 'test@example.com' });
+    throw new Error('Something went wrong');
+  });
+} catch (err) {
+  console.error('Transaction rolled back:', err.message);
+}
+```
+
+### Unique Constraint Violations
+
+```js
+try {
+  await Users.create({ email: 'existing@example.com' });
+} catch (err) {
+  if (err.code === 'SQLITE_CONSTRAINT' || err.code === '23505') {
+    throw new Error('Email already exists');
+  }
+  throw err;
+}
+```
+
+---
+
+## Best Practices
+
+### ✅ DO
+
+```js
+// Use transactions for multi-step operations
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Posts = tx.get('Posts');
+  
+  const user = await Users.create({ email });
+  await Posts.create({ title, author_id: user.id });
+});
+
+// Use include for eager loading
+const users = await Users.include('posts').find();
+
+// Check for null/undefined
+const user = await Users.where({ email }).first();
+if (!user) {
+  throw new Error('User not found');
+}
+
+// Update with write() or direct modification
+await user.write({ email: 'new@example.com' });
+// OR
+user.email = 'new@example.com'; // Auto-persists
+```
+
+### ❌ DON'T
+
+```js
+// Don't access unloaded relations
+const user = await Users.findById(1);
+console.log(user.posts.items); // May be undefined!
+
+// Don't mix transaction contexts
+await repo.transaction(async tx => {
+  const user = await repo.get('Users').create({ email }); // Wrong!
+  const post = await tx.get('Posts').create({ author_id: user.id });
+});
+
+// Don't use bulk operations with Knex directly (bypasses hooks!)
+await Users.query().where('active', false).delete(); // Anti-pattern!
+
+// Don't use methods that don't exist
+await user.update({ email }); // No such method!
+await user.save(); // No such method!
+await user.delete(); // Use unlink() instead!

+## CRUD Operations
+
+### Create a Record
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Simple create
+const user = await Users.create({
+  email: 'john@example.com',
+  name: 'John Doe'
+});
+
+// ✅ Create with default values
+const user = await Users.create({
+  email: 'jane@example.com'
+  // 'active' field uses default: true
+  // 'created_at' uses default: () => new Date()
+});
+
+// ❌ DON'T: Create without transaction for important data
+const user = await Users.create({ email }); // Risky if part of larger operation
+
+// ✅ DO: Use transactions for important creates
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const user = await Users.create({ email, name });
+});
+```
+
+### Read Records
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Find by ID (uses cache if enabled)
+const user = await Users.findById(1);
+if (!user) {
+  throw new Error('User not found');
+}
+
+// ✅ Find one by criteria
+const user = await Users.where({ email: 'john@example.com' }).first();
+
+// ✅ Find many with filters
+const activeUsers = await Users
+  .where({ active: true })
+  .orderBy('created_at', 'desc')
+  .limit(20)
+  .find();
+
+// ✅ Find with multiple conditions
+const users = await Users
+  .where({ active: true })
+  .where('created_at', '>', lastWeek)
+  .find();
+
+// ✅ Check if exists
+const exists = await Users.where({ email }).count() > 0;
+```
+
+### Update Records
 
 ```js
 const Users = repo.get('Users');
-const u = await Users.create({ email: 'a@example.com' });
-const found = await Users.findById(u.id);
+
+// ✅ Method 1: Direct modification (optimal for auto-persist)
+const user = await Users.findById(1);
+user.name = 'Jane Smith';
+user.updated_at = new Date();
+// Changes persist automatically on next query or transaction flush
+
+// ✅ Method 2: write() with key/value pairs (immediate flush)
+const user = await Users.findById(1);
+await user.write({ 
+  name: 'Jane Smith',
+  updated_at: new Date()
+});
+
+// ✅ Update with validation
+const user = await Users.findById(1);
+if (user.role !== 'admin') {
+  await user.write({ email: newEmail });
+}
+
+// ❌ DON'T: Bulk update using Knex directly (bypasses hooks!)
+await Users.query()
+  .where('last_login', '<', sixMonthsAgo)
+  .update({ active: false }); // Bypasses validation, hooks, NormalJS internals!
+
+// ✅ DO: Use transaction with individual updates (hooks run correctly)
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const users = await Users.where('last_login', '<', sixMonthsAgo).find();
+  for (const user of users) {
+    await user.write({ active: false });
+  }
+});
+
+// ❌ DON'T: Use update() method
+await user.update({ email: 'new@example.com' }); // Method doesn't exist!
+
+// ❌ DON'T: Modify then call write() without arguments
+user.email = 'new@example.com';
+await user.write(); // Anti-pattern!
+
+// ✅ DO: Use one of the two correct methods
+user.email = 'new@example.com'; // Direct (auto-persists)
+// OR
+await user.write({ email: 'new@example.com' }); // Immediate flush
+```
+
+### Delete Records
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Delete single record
+const user = await Users.findById(1);
+await user.unlink();
+
+// ✅ Delete with check
+const user = await Users.where({ email }).first();
+if (user && !user.is_protected) {
+  await user.unlink();
+}
+
+// ❌ DON'T: Bulk delete using Knex directly (bypasses hooks!)
+await Users.query()
+  .where('created_at', '<', oneYearAgo)
+  .where('active', false)
+  .delete(); // Bypasses hooks and cascade logic!
+
+// ✅ DO: Use transaction with individual deletes (hooks run correctly)
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const users = await Users
+    .where('created_at', '<', oneYearAgo)
+    .where('active', false)
+    .find();
+  for (const user of users) {
+    await user.unlink();
+  }
+});
+```
+
+## Queries & Filtering
+
+### Simple Filters
+
+```js
+const Posts = repo.get('Posts');
+
+// ✅ Single condition
+const posts = await Posts.where({ published: true }).find();
+
+// ✅ Multiple conditions (AND)
+const posts = await Posts
+  .where({ published: true, featured: true })
+  .find();
+
+// ✅ Comparison operators
+const posts = await Posts
+  .where('views', '>', 1000)
+  .where('created_at', '>=', lastMonth)
+  .find();
+
+// ✅ LIKE queries
+const posts = await Posts
+  .where('title', 'like', '%tutorial%')
+  .find();
+
+// ✅ IN queries
+const posts = await Posts
+  .whereIn('category_id', [1, 2, 3])
+  .find();
 ```
 
-- Simple filtering
+### Complex Filters with JSON Criteria
 
 ```js
-const posts = await repo.get('Posts').where({
+const Posts = repo.get('Posts');
+
+// ✅ OR conditions
+const posts = await Posts.where({
+  or: [
+    ['published', '=', true],
+    ['author_id', '=', currentUserId]
+  ]
+}).find();
+
+// ✅ Nested AND/OR
+const posts = await Posts.where({
+  and: [
+    ['published', '=', true],
+    {
+      or: [
+        ['featured', '=', true],
+        ['views', '>', 1000]
+      ]
+    }
+  ]
+}).find();
+
+// ✅ Complex search
+const posts = await Posts.where({
   and: [
-    ['author_id', '=', u.id],
     ['published', '=', true],
-  ],
+    {
+      or: [
+        ['title', 'like', `%${searchTerm}%`],
+        ['content', 'like', `%${searchTerm}%`]
+      ]
+    },
+    ['created_at', '>', startDate]
+  ]
+}).orderBy('views', 'desc').find();
+```
+
+### Sorting and Limiting
+
+```js
+const Posts = repo.get('Posts');
+
+// ✅ Order by single field
+const posts = await Posts
+  .where({ published: true })
+  .orderBy('created_at', 'desc')
+  .find();
+
+// ✅ Order by multiple fields
+const posts = await Posts
+  .where({ published: true })
+  .orderBy('featured', 'desc')
+  .orderBy('views', 'desc')
+  .find();
+
+// ✅ Pagination
+const page = 2;
+const perPage = 20;
+const posts = await Posts
+  .where({ published: true })
+  .limit(perPage)
+  .offset((page - 1) * perPage)
+  .find();
+```
+
+### Counting
+
+```js
+const Posts = repo.get('Posts');
+
+// ✅ Count all
+const total = await Posts.count();
+
+// ✅ Count with filters
+const publishedCount = await Posts
+  .where({ published: true })
+  .count();
+
+// ✅ Check existence
+const hasUnpublished = await Posts
+  .where({ published: false })
+  .count() > 0;
+```
+
+## Relations
+
+### Defining Relations
+
+```js
+// ✅ Many-to-One (belongs to)
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    author_id: { type: 'many-to-one', model: 'Users' } // Creates FK column
+  };
+}
+
+// ✅ One-to-Many (has many)
+class Users {
+  static _name = 'Users';
+  static fields = {
+    id: 'primary',
+    email: 'string',
+    posts: { type: 'one-to-many', foreign: 'Posts.author_id' } // Virtual field
+  };
+}
+
+// ✅ Many-to-Many
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    tags: { type: 'many-to-many', model: 'Tags' } // Auto-creates join table
+  };
+}
+
+class Tags {
+  static _name = 'Tags';
+  static fields = {
+    id: 'primary',
+    posts: { type: 'many-to-many', model: 'Posts' } // Same join table
+  };
+}
+```
+
+### Eager Loading Relations
+
+```js
+const Posts = repo.get('Posts');
+const Users = repo.get('Users');
+
+// ✅ Load single relation
+const post = await Posts
+  .where({ id: 1 })
+  .include('author')
+  .first();
+console.log(post.author.name);
+
+// ✅ Load multiple relations
+const post = await Posts
+  .where({ id: 1 })
+  .include('author', 'tags', 'comments')
+  .first();
+
+// ✅ Load relation on collection
+const posts = await Posts
+  .where({ published: true })
+  .include('author')
+  .find();
+posts.forEach(post => console.log(post.author.name));
+
+// ❌ DON'T: Access unloaded relations
+const post = await Posts.findById(1);
+console.log(post.author.name); // May be undefined!
+
+// ✅ DO: Load explicitly or use include
+const post = await Posts.findById(1);
+await post.author.load();
+console.log(post.author.name);
+```
+
+### Lazy Loading Relations
+
+```js
+const Posts = repo.get('Posts');
+const Users = repo.get('Users');
+
+// ✅ Load one-to-many
+const user = await Users.findById(1);
+await user.posts.load();
+console.log(`User has ${user.posts.items.length} posts`);
+
+// ✅ Load with filters
+const user = await Users.findById(1);
+const publishedPosts = await user.posts.where({ published: true });
+
+// ✅ Load many-to-many
+const post = await Posts.findById(1);
+await post.tags.load();
+post.tags.items.forEach(tag => console.log(tag.name));
+```
+
+### Managing Many-to-Many Relations
+
+```js
+const Posts = repo.get('Posts');
+
+// ✅ Add relation
+const post = await Posts.findById(1);
+await post.tags.add(tagId);
+await post.tags.add(tagObject);
+
+// ✅ Remove relation
+await post.tags.remove(tagId);
+
+// ✅ Replace all relations
+await post.tags.set([tag1Id, tag2Id, tag3Id]);
+
+// ✅ Clear all relations
+await post.tags.set([]);
+
+// ✅ Check if related
+await post.tags.load();
+const hasTag = post.tags.items.some(t => t.id === tagId);
+```
+
+## Transactions
+
+### Basic Transaction
+
+```js
+// ✅ Simple transaction
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Posts = tx.get('Posts');
+  
+  const user = await Users.create({ email: 'author@example.com' });
+  await Posts.create({ title: 'First Post', author_id: user.id });
+  
+  // Commits automatically on success
+});
+
+// ❌ DON'T: Mix transaction contexts
+await repo.transaction(async tx => {
+  const user = await repo.get('Users').create({ email }); // Wrong context!
+  const post = await tx.get('Posts').create({ author_id: user.id });
+});
+
+// ✅ DO: Use tx consistently
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Posts = tx.get('Posts');
+  
+  const user = await Users.create({ email });
+  const post = await Posts.create({ author_id: user.id });
 });
 ```
 
-- Relations
+### Transaction with Error Handling
 
 ```js
-// One-to-many
-const posts = await u.posts.where({ published: true });
+// ✅ Transaction with rollback on error
+try {
+  await repo.transaction(async tx => {
+    const Users = tx.get('Users');
+    const Accounts = tx.get('Accounts');
+    
+    const user = await Users.create({ email });
+    
+    // This will rollback if it throws
+    if (someCondition) {
+      throw new Error('Invalid operation');
+    }
+    
+    await Accounts.create({ user_id: user.id, balance: 0 });
+  });
+} catch (err) {
+  console.error('Transaction failed:', err.message);
+  // All changes rolled back
+}
 ```
 
-- Transactions
+### Nested Operations in Transaction
 
 ```js
-await repo.transaction(async (tx) => {
+// ✅ Complex multi-step transaction
+await repo.transaction(async tx => {
   const Users = tx.get('Users');
-  await Users.create({ email: 'tx@example.com' });
+  const Orders = tx.get('Orders');
+  const Products = tx.get('Products');
+  const OrderItems = tx.get('OrderItems');
+  
+  // 1. Get user
+  const user = await Users.findById(userId);
+  if (!user.active) {
+    throw new Error('User is not active');
+  }
+  
+  // 2. Create order
+  const order = await Orders.create({
+    customer_id: user.id,
+    status: 'pending',
+    total: 0
+  });
+  
+  // 3. Process items
+  let total = 0;
+  for (const item of cartItems) {
+    const product = await Products.findById(item.product_id);
+    
+    // Check stock
+    if (product.stock < item.quantity) {
+      throw new Error(`Not enough stock for ${product.name}`);
+    }
+    
+    // Deduct inventory
+    await product.write({ stock: product.stock - item.quantity });
+    
+    // Create order item
+    await OrderItems.create({
+      order_id: order.id,
+      product_id: product.id,
+      quantity: item.quantity,
+      price: product.price
+    });
+    
+    total += product.price * item.quantity;
+  }
+  
+  // 4. Update order total
+  await order.write({ total });
+});
+```
+
+## Authentication
+
+### Password Hashing (with bcrypt)
+
+```js
+// ✅ User model with password hashing
+class Users {
+  static _name = 'Users';
+  static fields = {
+    id: 'primary',
+    email: { type: 'string', unique: true, required: true },
+    password_hash: 'string'
+  };
+  
+  // Set password with hashing
+  async setPassword(password) {
+    const bcrypt = require('bcrypt');
+    const hash = await bcrypt.hash(password, 10);
+    await this.write({ password_hash: hash });
+  }
+  
+  // Verify password
+  async verifyPassword(password) {
+    const bcrypt = require('bcrypt');
+    return bcrypt.compare(password, this.password_hash);
+  }
+  
+  // Static method for authentication
+  static async authenticate(email, password) {
+    const user = await this.where({ email }).first();
+    if (!user) return null;
+    
+    const valid = await user.verifyPassword(password);
+    return valid ? user : null;
+  }
+}
+
+// Usage
+const Users = repo.get('Users');
+
+// Register
+const user = await Users.create({ email: 'john@example.com' });
+await user.setPassword('secretpassword');
+
+// Login
+const user = await Users.authenticate('john@example.com', 'secretpassword');
+if (!user) {
+  throw new Error('Invalid credentials');
+}
+```
+
+### Session Management
+
+```js
+// ✅ Session model
+class Sessions {
+  static _name = 'Sessions';
+  static fields = {
+    id: 'primary',
+    user_id: { type: 'many-to-one', model: 'Users' },
+    token: { type: 'string', unique: true },
+    expires_at: 'datetime',
+    created_at: { type: 'datetime', default: () => new Date() }
+  };
+  
+  // Check if session is valid
+  get isValid() {
+    return this.expires_at > new Date();
+  }
+  
+  // Create new session
+  static async createForUser(userId, ttlSeconds = 86400) {
+    const crypto = require('crypto');
+    const token = crypto.randomBytes(32).toString('hex');
+    const expiresAt = new Date(Date.now() + ttlSeconds * 1000);
+    
+    return this.create({
+      user_id: userId,
+      token,
+      expires_at: expiresAt
+    });
+  }
+  
+  // Find by token
+  static async findByToken(token) {
+    const session = await this.where({ token }).first();
+    if (!session || !session.isValid) {
+      return null;
+    }
+    return session;
+  }
+}
+
+// Usage
+const Sessions = repo.get('Sessions');
+
+// Create session
+const session = await Sessions.createForUser(user.id);
+console.log('Session token:', session.token);
+
+// Validate session
+const session = await Sessions.findByToken(token);
+if (!session) {
+  throw new Error('Invalid or expired session');
+}
+```
+
+## Pagination
+
+### Simple Pagination
+
+```js
+// ✅ Basic pagination helper
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    published: 'boolean'
+  };
+  
+  // Static pagination method
+  static async paginate(page = 1, perPage = 20, filters = {}) {
+    const offset = (page - 1) * perPage;
+    
+    // Build base query
+    let query = this.where(filters);
+    
+    // Get items and total count in parallel
+    const [items, total] = await Promise.all([
+      query.limit(perPage).offset(offset).find(),
+      query.count()
+    ]);
+    
+    return {
+      items,
+      total,
+      page,
+      perPage,
+      totalPages: Math.ceil(total / perPage),
+      hasNext: page * perPage < total,
+      hasPrev: page > 1
+    };
+  }
+}
+
+// Usage
+const Posts = repo.get('Posts');
+const result = await Posts.paginate(2, 20, { published: true });
+
+console.log(`Page ${result.page} of ${result.totalPages}`);
+console.log(`Showing ${result.items.length} of ${result.total} posts`);
+result.items.forEach(post => console.log(post.title));
+```
+
+### Cursor-Based Pagination
+
+```js
+// ✅ Cursor pagination for infinite scroll
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    created_at: 'datetime'
+  };
+  
+  // Cursor-based pagination
+  static async paginateByCursor(cursor = null, limit = 20) {
+    let query = this.where({ published: true });
+    
+    if (cursor) {
+      // Get posts created before cursor
+      query = query.where('created_at', '<', cursor);
+    }
+    
+    const items = await query
+      .orderBy('created_at', 'desc')
+      .limit(limit + 1) // Get one extra to check if there's more
+      .find();
+    
+    const hasMore = items.length > limit;
+    if (hasMore) items.pop(); // Remove the extra item
+    
+    const nextCursor = items.length > 0
+      ? items[items.length - 1].created_at
+      : null;
+    
+    return {
+      items,
+      nextCursor,
+      hasMore
+    };
+  }
+}
+
+// Usage
+const Posts = repo.get('Posts');
+
+// First page
+const page1 = await Posts.paginateByCursor();
+console.log(`Loaded ${page1.items.length} posts`);
+
+// Next page
+if (page1.hasMore) {
+  const page2 = await Posts.paginateByCursor(page1.nextCursor);
+  console.log(`Loaded ${page2.items.length} more posts`);
+}
+```
+
+## Timestamps
+
+### Auto Timestamps
+
+```js
+// ✅ Model with automatic timestamps
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    created_at: { type: 'datetime', default: () => new Date() },
+    updated_at: { type: 'datetime', default: () => new Date() }
+  };
+}
+
+// ✅ Update with timestamp
+const post = await Posts.findById(1);
+await post.write({
+  title: 'New Title',
+  updated_at: new Date()
 });
 ```
+
+### Post-Create Hook for Timestamps
+
+```js
+// ✅ Automatic updated_at using hooks
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    created_at: { type: 'datetime', default: () => new Date() },
+    updated_at: { type: 'datetime', default: () => new Date() }
+  };
+  
+  // Post-create hook
+  async post_create() {
+    // Run after record is created
+    console.log(`Post ${this.id} created at ${this.created_at}`);
+  }
+  
+  // Pre-update hook
+  async pre_update() {
+    this.updated_at = new Date();
+  }
+}
+```
+
+## Soft Deletes
+
+### Implementing Soft Deletes
+
+```js
+// ✅ Soft delete pattern
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    deleted_at: 'datetime'
+  };
+  
+  // Soft delete
+  async softDelete() {
+    await this.write({ deleted_at: new Date() });
+  }
+  
+  // Restore
+  async restore() {
+    await this.write({ deleted_at: null });
+  }
+  
+  // Check if deleted
+  get isDeleted() {
+    return this.deleted_at !== null;
+  }
+  
+  // Query only active records
+  static active() {
+    return this.where({ deleted_at: null });
+  }
+  
+  // Query only deleted records
+  static deleted() {
+    return this.where('deleted_at', 'is not', null);
+  }
+}
+
+// Usage
+const Posts = repo.get('Posts');
+
+// Get only active posts
+const activePosts = await Posts.active().find();
+
+// Soft delete
+const post = await Posts.findById(1);
+await post.softDelete();
+
+// Restore
+await post.restore();
+
+// Get deleted posts
+const deletedPosts = await Posts.deleted().find();
+```
+
+## Slugs & SEO
+
+### Auto-Generate Slugs
+
+```js
+// ✅ Slug generation
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: { type: 'string', required: true },
+    slug: { type: 'string', unique: true }
+  };
+  
+  // Generate slug from title
+  static generateSlug(title) {
+    return title
+      .toLowerCase()
+      .replace(/[^a-z0-9]+/g, '-')
+      .replace(/(^-|-$)/g, '');
+  }
+  
+  // Ensure unique slug
+  static async ensureUniqueSlug(slug, excludeId = null) {
+    let uniqueSlug = slug;
+    let counter = 1;
+    
+    while (true) {
+      let query = this.where({ slug: uniqueSlug });
+      if (excludeId) {
+        query = query.where('id', '!=', excludeId);
+      }
+      
+      const exists = await query.count() > 0;
+      if (!exists) break;
+      
+      uniqueSlug = `${slug}-${counter++}`;
+    }
+    
+    return uniqueSlug;
+  }
+  
+  // Post-create hook to generate slug
+  async post_create() {
+    if (!this.slug) {
+      const baseSlug = Posts.generateSlug(this.title);
+      const uniqueSlug = await Posts.ensureUniqueSlug(baseSlug, this.id);
+      await this.write({ slug: uniqueSlug });
+    }
+  }
+  
+  // Find by slug
+  static bySlug(slug) {
+    return this.where({ slug }).first();
+  }
+}
+
+// Usage
+const Posts = repo.get('Posts');
+
+// Create with auto-slug
+const post = await Posts.create({
+  title: 'Hello World!'
+});
+console.log(post.slug); // "hello-world"
+
+// Find by slug
+const post = await Posts.bySlug('hello-world');
+```
+
+## File Uploads
+
+### File Metadata Model
+
+```js
+// ✅ File upload model
+class Uploads {
+  static _name = 'Uploads';
+  static fields = {
+    id: 'primary',
+    filename: 'string',
+    original_name: 'string',
+    mime_type: 'string',
+    size: 'integer',
+    path: 'string',
+    user_id: { type: 'many-to-one', model: 'Users' },
+    created_at: { type: 'datetime', default: () => new Date() }
+  };
+  
+  // Get public URL
+  get url() {
+    return `/uploads/${this.filename}`;
+  }
+  
+  // Get human-readable size
+  get humanSize() {
+    const bytes = this.size;
+    if (bytes < 1024) return `${bytes} B`;
+    if (bytes < 1024 * 1024) return `${(bytes / 1024).toFixed(1)} KB`;
+    return `${(bytes / (1024 * 1024)).toFixed(1)} MB`;
+  }
+  
+  // Create from file
+  static async createFromFile(filePath, originalName, userId) {
+    const fs = require('fs');
+    const path = require('path');
+    const crypto = require('crypto');
+    
+    const stats = fs.statSync(filePath);
+    const ext = path.extname(originalName);
+    const filename = crypto.randomBytes(16).toString('hex') + ext;
+    
+    // You would move/copy the file here
+    // fs.renameSync(filePath, `/uploads/${filename}`);
+    
+    return this.create({
+      filename,
+      original_name: originalName,
+      mime_type: 'application/octet-stream', // Detect from file
+      size: stats.size,
+      path: `/uploads/${filename}`,
+      user_id: userId
+    });
+  }
+}
+
+// Usage
+const Uploads = repo.get('Uploads');
+
+const upload = await Uploads.createFromFile(
+  '/tmp/upload-abc123',
+  'document.pdf',
+  userId
+);
+
+console.log(`File uploaded: ${upload.url}`);
+console.log(`Size: ${upload.humanSize}`);
+```
+
+## Validation
+
+### Field-Level Validation
+
+```js
+// ✅ Custom validation in model
+class Users {
+  static _name = 'Users';
+  static fields = {
+    id: 'primary',
+    email: { type: 'string', unique: true, required: true },
+    age: 'integer'
+  };
+  
+  // Pre-create validation
+  async pre_create() {
+    this.validateEmail();
+    this.validateAge();
+  }
+  
+  // Pre-update validation
+  async pre_update() {
+    if ('email' in this._changes) {
+      this.validateEmail();
+    }
+    if ('age' in this._changes) {
+      this.validateAge();
+    }
+  }
+  
+  validateEmail() {
+    const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
+    if (!emailRegex.test(this.email)) {
+      throw new Error('Invalid email format');
+    }
+  }
+  
+  validateAge() {
+    if (this.age !== null && this.age !== undefined) {
+      if (this.age < 0 || this.age > 150) {
+        throw new Error('Age must be between 0 and 150');
+      }
+    }
+  }
+}
+
+// Usage (validation happens automatically)
+try {
+  const user = await Users.create({
+    email: 'invalid-email',
+    age: 200
+  });
+} catch (err) {
+  console.error(err.message); // "Invalid email format"
+}
+```
+
+## Search
+
+### Simple Full-Text Search
+
+```js
+// ✅ Basic search across multiple fields
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    content: 'text',
+    published: 'boolean'
+  };
+  
+  // Search method
+  static search(term, filters = {}) {
+    const searchPattern = `%${term}%`;
+    
+    return this.where({
+      and: [
+        ...Object.entries(filters).map(([k, v]) => [k, '=', v]),
+        {
+          or: [
+            ['title', 'like', searchPattern],
+            ['content', 'like', searchPattern]
+          ]
+        }
+      ]
+    });
+  }
+}
+
+// Usage
+const Posts = repo.get('Posts');
+
+const results = await Posts
+  .search('javascript', { published: true })
+  .orderBy('created_at', 'desc')
+  .limit(10)
+  .find();
+
+console.log(`Found ${results.length} posts matching "javascript"`);
+```
+
+### Search with Relevance Scoring (PostgreSQL)
+
+```js
+// ✅ Full-text search with PostgreSQL
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    content: 'text',
+    search_vector: 'text' // tsvector column
+  };
+  
+  // Search with ranking
+  static async searchFullText(term, limit = 20) {
+    const query = this.query()
+      .select('*')
+      .select(this.query().raw(
+        "ts_rank(search_vector, plainto_tsquery('english', ?)) as rank",
+        [term]
+      ))
+      .whereRaw(
+        "search_vector @@ plainto_tsquery('english', ?)",
+        [term]
+      )
+      .orderBy('rank', 'desc')
+      .limit(limit);
+    
+    return query;
+  }
+  
+  // Update search vector (trigger or hook)
+  async post_update() {
+    if ('title' in this._changes || 'content' in this._changes) {
+      // Update search vector for full-text search
+      await this.query()
+        .where({ id: this.id })
+        .update({
+          search_vector: this.query().raw(
+            "to_tsvector('english', ? || ' ' || ?)",
+            [this.title, this.content]
+          )
+        });
+    }
+  }
+}

+## Quick Start
+
+### Installation
+
+```bash
+npm install normaljs knex sqlite3
+# or for PostgreSQL: npm install normaljs knex pg
+# or for MySQL: npm install normaljs knex mysql2
+```
+
+### Complete Working Example
 
 ```js
 const { Connection, Repository } = require('normaljs');
 
-const conn = new Connection({ client: 'sqlite3', connection: { filename: ':memory:' } });
-await conn.connect();
+// 1. Setup connection and repository
+const conn = new Connection({
+  client: 'sqlite3',
+  connection: { filename: ':memory:' }
+});
 const repo = new Repository(conn);
 
+// 2. Define models with relations
 class Users {
   static _name = 'Users';
-  static fields = { id: 'primary', email: 'string' };
+  static fields = {
+    id: 'primary',
+    email: { type: 'string', unique: true, required: true },
+    name: 'string',
+    active: { type: 'boolean', default: true },
+    posts: { type: 'one-to-many', foreign: 'Posts.author_id' }
+  };
+  
+  // Add instance methods
+  get domain() {
+    return this.email.split('@')[1];
+  }
+  
+  // Add static query helpers
+  static activeUsers() {
+    return this.where({ active: true });
+  }
+}
+
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: { type: 'string', required: true },
+    content: 'text',
+    published: { type: 'boolean', default: false },
+    author_id: { type: 'many-to-one', model: 'Users' },
+    tags: { type: 'many-to-many', model: 'Tags' }
+  };
 }
-repo.register(Users);
-await repo.sync({ force: true });
 
-const u = await repo.get('Users').create({ email: 'a@example.com' });
+class Tags {
+  static _name = 'Tags';
+  static fields = {
+    id: 'primary',
+    name: { type: 'string', unique: true }
+  };
+}
+
+// 3. Register models and sync schema
+repo.register(Users, Posts, Tags);
+await repo.sync({ force: true }); // Dev only!
+
+// 4. Create records
+const UsersModel = repo.get('Users');
+const PostsModel = repo.get('Posts');
+const TagsModel = repo.get('Tags');
+
+const user = await UsersModel.create({
+  email: 'john@example.com',
+  name: 'John Doe'
+});
+
+// 5. Create with relations in a transaction
+await repo.transaction(async tx => {
+  const Posts = tx.get('Posts');
+  const Tags = tx.get('Tags');
+  
+  const tag = await Tags.create({ name: 'tutorial' });
+  
+  const post = await Posts.create({
+    title: 'Getting Started with NormalJS',
+    content: 'This is a comprehensive guide...',
+    author_id: user.id,
+    tags: [tag.id] // Creates many-to-many relations
+  });
+});
+
+// 6. Query with eager loading
+const userWithPosts = await UsersModel
+  .where({ email: 'john@example.com' })
+  .include('posts')
+  .first();
+
+console.log(`${userWithPosts.name} has ${userWithPosts.posts.items.length} posts`);
+
+// 7. Query posts with filters
+const publishedPosts = await PostsModel
+  .where({ published: true })
+  .orderBy('created_at', 'desc')
+  .limit(10)
+  .include('author', 'tags')
+  .find();
+
+// 8. Use instance methods
+console.log(`User domain: ${user.domain}`); // "example.com"
+
+// 9. Update records - Two ways:
+// Method 1: Direct modification (persists automatically)
+user.name = 'John Smith';
+
+// Method 2: write() with key/value pairs (immediate flush)
+await user.write({ name: 'John Smith', updated_at: new Date() });
+
+// 10. Work with relations
+const post = await PostsModel.findById(1);
+await post.tags.load();
+await post.tags.add(newTagId);
+```
+
+## Common Tasks
+
+### How to: Define a Model
+
+```js
+class Products {
+  static _name = 'Products'; // Required: registry key
+  static table = 'products'; // Optional: DB table name
+  static cache = 300; // Optional: cache TTL in seconds
+  
+  static fields = {
+    id: 'primary',
+    name: { type: 'string', required: true },
+    price: { type: 'float', default: 0 },
+    in_stock: { type: 'boolean', default: true }
+  };
+}
+```
+
+### How to: Create Records
+
+```js
+const Products = repo.get('Products');
+
+// Single record
+const product = await Products.create({
+  name: 'Laptop',
+  price: 999.99
+});
+
+// In a transaction (recommended for writes)
+await repo.transaction(async tx => {
+  const Products = tx.get('Products');
+  await Products.create({ name: 'Mouse', price: 29.99 });
+  await Products.create({ name: 'Keyboard', price: 79.99 });
+});
 ```
 
-What’s next
+### How to: Query Records
+
+```js
+const Products = repo.get('Products');
+
+// Find by ID
+const product = await Products.findById(1);
+
+// Find one by condition
+const product = await Products.where({ name: 'Laptop' }).first();
+
+// Find many with filters
+const products = await Products
+  .where({ in_stock: true })
+  .where('price', '<', 100)
+  .orderBy('price', 'asc')
+  .limit(10)
+  .find();
+
+// Complex conditions with JSON criteria
+const products = await Products.where({
+  and: [
+    ['in_stock', '=', true],
+    { or: [
+      ['price', '<', 50],
+      ['name', 'like', '%sale%']
+    ]}
+  ]
+}).find();
+
+// Count records
+const count = await Products.where({ in_stock: true }).count();
+```
+
+### How to: Work with Relations
+
+```js
+// Define relations
+class Orders {
+  static _name = 'Orders';
+  static fields = {
+    id: 'primary',
+    customer_id: { type: 'many-to-one', model: 'Customers' },
+    items: { type: 'one-to-many', foreign: 'OrderItems.order_id' }
+  };
+}
+
+// Eager load relations
+const order = await Orders
+  .where({ id: 1 })
+  .include('customer', 'items')
+  .first();
+
+// Lazy load relations
+const order = await Orders.findById(1);
+await order.items.load();
+
+// Manage many-to-many
+const post = await Posts.findById(1);
+await post.tags.add(tagId); // Add relation
+await post.tags.remove(tagId); // Remove relation
+await post.tags.set([id1, id2]); // Replace all
+```
+
+### How to: Update and Delete
+
+```js
+// Update - Method 1: Direct modification (optimal)
+const product = await Products.findById(1);
+product.price = 899.99;
+product.updated_at = new Date();
+// Changes persist automatically on next query or transaction flush
+
+// Update - Method 2: write() with key/value pairs (immediate flush)
+const product = await Products.findById(1);
+await product.write({ 
+  price: 899.99, 
+  updated_at: new Date() 
+});
+
+// Delete a record
+await product.unlink();
+
+// Bulk operations (use Knex query builder)
+await Products.query()
+  .where('price', '<', 10)
+  .update({ in_stock: false });
+```
+
+### How to: Use Transactions
+
+```js
+// Always use transactions for multi-step operations
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Orders = tx.get('Orders');
+  const Products = tx.get('Products');
+  
+  const user = await Users.findById(userId);
+  const product = await Products.findById(productId);
+  
+  // Deduct inventory
+  await product.write({ stock: product.stock - 1 });
+  
+  // Create order
+  const order = await Orders.create({
+    customer_id: user.id,
+    product_id: product.id,
+    total: product.price
+  });
+  
+  // Commits automatically on success, rolls back on error
+});
+```

 # Models
 
 NormalJS models are ES6 classes that declare metadata via static properties. They map to database tables, expose a fluent query API, and return active record instances (objects with getters/methods).
 
-See fields reference in `docs/FIELDS.md` for all column types and relation options.
+## Quick Reference
 
-## Minimal example
+✅ **DO:**
+- Always include `static _name` (required for registration)
+- Use `static fields` for schema definition
+- Add instance methods/getters for computed properties
+- Add static methods for custom query scopes
+- Use transactions for multi-step operations
+
+❌ **DON'T:**
+- Never instantiate with `new ModelClass()`
+- Don't forget `static _name` 
+- Don't modify record properties directly (use `update()`)
+- Don't access relations without loading them first
+- Don't use `sync({ force: true })` in production
+

 ```js
 class Users {
-  static _name = 'Users'; // Registry key (required)
-  static table = 'users'; // DB table (optional; inferred from name)
-  static cache = true; // Enable cache (true=default TTL, or a number in seconds)
+  static _name = 'Users'; // REQUIRED: Registry key
+  static table = 'users'; // Optional: DB table (defaults to snake_case of _name)
+  static cache = 300; // Optional: Enable cache with 300s TTL
 
   static fields = {
-    id: 'primary',
+    id: 'primary', // Auto-increment primary key
     email: { type: 'string', unique: true, required: true },
     active: { type: 'boolean', default: true },
     created_at: { type: 'datetime', default: () => new Date() },
   };
 
-  // Instance API works on active records
+  // Instance methods work on active records
   get isStaff() {
-    return this.email.endsWith('@example.com');
+    return this.email?.endsWith('@example.com');
+  }
+  
+  // Static methods for query scopes
+  static activeUsers() {
+    return this.where({ active: true });
   }
 }
+
+// Register the model
+repo.register(Users);
+
+// Access via repository
+const Users = repo.get('Users');
 ```
 
-- `static _name` is mandatory and used as the model key in the repository registry.
-- `static table` defaults to a snake_cased form of `name` (e.g. `Users` -> `users`).
-- `static cache` can be `true` (uses default TTL of 300s) or a number (TTL seconds). Disable per model by omitting or setting falsy. The global cache must also be enabled at the repository level via env; see `src/Repository.js`.
+### Model Properties
 
-## Defining fields and relations
+| Property | Required | Description | Example |
+|----------|----------|-------------|---------|
+| `static _name` | ✅ Yes | Registry key for the model | `'Users'`, `'BlogPosts'` |
+| `static table` | ❌ No | Database table name | `'users'`, `'blog_posts'` |
+| `static fields` | ✅ Yes | Field definitions | `{ id: 'primary', ... }` |
+| `static cache` | ❌ No | Cache TTL (seconds) or `true` for default (300s) | `300`, `true`, `false` |
+| `static indexes` | ❌ No | Index definitions | `['email', ['name', 'age']]` |
 
-Declare columns and relations under `static fields`. See `docs/FIELDS.md` for full details. Quick summary:
+### Field Types
 
-- Primitives: `primary`, `integer|number`, `float`, `boolean`, `string`, `text`, `date`, `datetime|timestamp`, `enum`, `json`, `reference`.
-- Relations:
-  - Many-to-one: `{ type: 'many-to-one', model: 'OtherModel', cascade?: boolean }`
-  - One-to-many: `{ type: 'one-to-many', foreign: 'ChildModel.fkField' }`
-  - Many-to-many: `{ type: 'many-to-many', model: 'OtherModel', joinTable?: 'rel_custom' }`
+Quick reference (see [Fields](fields) for complete documentation):
 
-Example with relations:
+```js
+static fields = {
+  // Primary key (shorthand)
+  id: 'primary', // Auto-increment integer PK
+  
+  // Basic types
+  name: 'string',           // VARCHAR(255)
+  age: 'integer',           // INTEGER
+  price: 'float',           // FLOAT/DOUBLE
+  active: 'boolean',        // BOOLEAN
+  bio: 'text',              // TEXT
+  data: 'json',             // JSON/JSONB
+  created: 'datetime',      // DATETIME/TIMESTAMP
+  birthday: 'date',         // DATE
+  
+  // With constraints
+  email: { type: 'string', unique: true, required: true, size: 255 },
+  count: { type: 'integer', default: 0, index: true },
+  score: { type: 'float', precision: 2 },
+  status: { type: 'enum', values: ['draft', 'published', 'archived'] },
+  
+  // Relations
+  author_id: { type: 'many-to-one', model: 'Users' }, // FK column
+  posts: { type: 'one-to-many', foreign: 'Posts.author_id' }, // Virtual
+  tags: { type: 'many-to-many', model: 'Tags' } // Auto join table
+}
+```
+
+## Defining Relations
+
+### Many-to-One (Belongs To)
+
+Creates a foreign key column on the current model.
 
 ```js
+// ✅ Correct: Define many-to-one relation
 class Posts {
   static _name = 'Posts';
   static fields = {
     id: 'primary',
-    title: { type: 'string', unique: true },
-    content: { type: 'text', required: true },
-    author: { type: 'many-to-one', model: 'Users' },
-    tags: { type: 'many-to-many', model: 'Tags' },
-    comments: { type: 'one-to-many', foreign: 'Comments.post' },
+    title: 'string',
+    author_id: { type: 'many-to-one', model: 'Users' }, // Creates FK column
   };
 }
+
+// Usage
+const post = await Posts.findById(1);
+await post.author.load(); // Load related user
+console.log(post.author.email);
+
+// Change relation - Method 1: Direct modification
+post.author_id = newUserId;
+// Persists automatically
+
+// Change relation - Method 2: write() with key/value pairs
+await post.write({ author_id: newUserId });
 ```
 
-## Querying and active records
+### One-to-Many (Has Many)
 
-- `Model.query()` returns a query builder proxy. Chain any Knex method (e.g., `where`, `join`, `limit`, `orderBy`).
-- `Model.where(...)` is a shorthand for `Model.query().where(...)`.
-- `await Model.findById(id)` resolves an active record by id (uses in-memory identity map and cache when enabled).
-- `await Model.firstWhere(cond)` returns the first matching record.
+Virtual field that queries the inverse many-to-one relation.
 
-Results are wrapped into active record instances. With cache enabled, read queries initially select only `id` for performance; accessing other fields triggers batched fetching behind the scenes.
+```js
+// ✅ Correct: Define one-to-many relation
+class Users {
+  static _name = 'Users';
+  static fields = {
+    id: 'primary',
+    email: 'string',
+    posts: { type: 'one-to-many', foreign: 'Posts.author_id' }, // Virtual field
+  };
+}
 
-## Creating and flushing
+// Usage
+const user = await Users.findById(1);
+await user.posts.load(); // Load all posts where author_id = user.id
+console.log(`User has ${user.posts.items.length} posts`);
 
-- `await Model.create(data)` inserts a new record and returns an active record instance. Many-to-many collections can be pre-filled by setting the relation field to an array of ids (they are written after the main row is inserted).
-- `await repo.flush()` persists pending changes across all models. `await model.flush()` flushes one model.
+// Query with filters
+const publishedPosts = await user.posts.where({ published: true });
+```
 
-## Indexes and Unique Constraints
+### Many-to-Many
 
-You can define indexes and unique constraints at the model level using the `static indexes` property. This is useful for composite indexes, partial indexes, and fine-grained control over index behavior.
+Automatically creates a join table.
 
-### Simple syntax (array)
+```js
+// ✅ Correct: Define many-to-many relation
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    tags: { type: 'many-to-many', model: 'Tags' }, // Auto-creates rel_posts_tags
+  };
+}
+
+class Tags {
+  static _name = 'Tags';
+  static fields = {
+    id: 'primary',
+    name: 'string',
+    posts: { type: 'many-to-many', model: 'Posts' }, // Same join table
+  };
+}
+
+// Usage
+const post = await Posts.findById(1);
+
+// Load relations
+await post.tags.load();
+post.tags.items.forEach(tag => console.log(tag.name));
+
+// Manage relations
+await post.tags.add(tagId);        // Add a tag
+await post.tags.remove(tagId);     // Remove a tag
+await post.tags.set([id1, id2]);   // Replace all tags
+
+// Create with relations
+const post = await Posts.create({
+  title: 'Hello World',
+  tags: [tagId1, tagId2] // Automatically creates relations
+});
+```
+
+### Common Relation Patterns
+
+```js
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    content: 'text',
+    
+    // Many-to-one relations (FK columns)
+    author_id: { type: 'many-to-one', model: 'Users' },
+    category_id: { type: 'many-to-one', model: 'Categories', cascade: true },
+    
+    // One-to-many relations (virtual)
+    comments: { type: 'one-to-many', foreign: 'Comments.post_id' },
+    
+    // Many-to-many relations (join table)
+    tags: { type: 'many-to-many', model: 'Tags', joinTable: 'posts_tags' }
+  };
+}
+```
+
+## Querying Models
+
+### Basic Queries
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Find by ID (uses cache)
+const user = await Users.findById(1);
+
+// ✅ Find one by condition
+const user = await Users.where({ email: 'john@example.com' }).first();
+
+// ❌ DON'T: Forget to check for null
+const user = await Users.where({ email }).first();
+console.log(user.name); // May throw if user is null!
+
+// ✅ DO: Always check for null
+const user = await Users.where({ email }).first();
+if (!user) {
+  throw new Error('User not found');
+}
+
+// ✅ Find many with filters
+const users = await Users
+  .where({ active: true })
+  .orderBy('created_at', 'desc')
+  .limit(10)
+  .find();
+
+// ✅ Count records
+const count = await Users.where({ active: true }).count();
+
+// ✅ Check existence
+const exists = await Users.where({ email }).count() > 0;
+```
+
+### Complex Filters
+
+```js
+const Posts = repo.get('Posts');
+
+// ✅ Multiple conditions (AND)
+const posts = await Posts
+  .where({ published: true })
+  .where('views', '>', 1000)
+  .where('created_at', '>=', lastMonth)
+  .find();
+
+// ✅ JSON criteria with OR
+const posts = await Posts.where({
+  and: [
+    ['published', '=', true],
+    {
+      or: [
+        ['featured', '=', true],
+        ['views', '>', 1000]
+      ]
+    }
+  ]
+}).find();
+
+// ✅ LIKE queries
+const posts = await Posts
+  .where('title', 'like', '%tutorial%')
+  .find();
+
+// ✅ IN queries
+const posts = await Posts
+  .whereIn('category_id', [1, 2, 3])
+  .find();
+```
+
+### Eager Loading Relations
+
+```js
+const Posts = repo.get('Posts');
+
+// ✅ Load single relation
+const posts = await Posts
+  .where({ published: true })
+  .include('author')
+  .find();
+
+// ✅ Load multiple relations
+const post = await Posts
+  .where({ id: 1 })
+  .include('author', 'tags', 'comments')
+  .first();
+
+// ❌ DON'T: Access unloaded relations
+const post = await Posts.findById(1);
+console.log(post.author.name); // May be undefined!
+
+// ✅ DO: Load relations first
+const post = await Posts
+  .where({ id: 1 })
+  .include('author')
+  .first();
+console.log(post.author.name);
+
+// ✅ OR: Lazy load
+const post = await Posts.findById(1);
+await post.author.load();
+console.log(post.author.name);
+```
+
+### Custom Query Scopes
+
+```js
+// ✅ Add static methods for reusable queries
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    published: 'boolean',
+    featured: 'boolean',
+    views: 'integer'
+  };
+  
+  // Query scope for published posts
+  static published() {
+    return this.where({ published: true });
+  }
+  
+  // Query scope for popular posts
+  static popular(minViews = 1000) {
+    return this.where('views', '>=', minViews);
+  }
+  
+  // Combine scopes
+  static trending() {
+    return this.published()
+      .where({ featured: true })
+      .orderBy('views', 'desc');
+  }
+}
+
+// Usage
+const Posts = repo.get('Posts');
+const trendingPosts = await Posts.trending().limit(10).find();
+const popularPublished = await Posts.published().popular(5000).find();
+```
+
+## Creating and Updating Records
+
+### Create Records
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Simple create
+const user = await Users.create({
+  email: 'john@example.com',
+  name: 'John Doe'
+});
+
+// ❌ DON'T: Create without transaction for multi-step ops
+const user = await Users.create({ email });
+const profile = await Profiles.create({ user_id: user.id }); // Not atomic!
+
+// ✅ DO: Use transactions
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const Profiles = tx.get('Profiles');
+  
+  const user = await Users.create({ email });
+  await Profiles.create({ user_id: user.id });
+});
+
+// ✅ Create with relations
+const post = await Posts.create({
+  title: 'Hello World',
+  author_id: userId,
+  tags: [tagId1, tagId2] // Creates many-to-many relations
+});
+```
+
+### Update Records
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Method 1: Direct modification (optimal for auto-persist)
+const user = await Users.findById(1);
+user.name = 'Jane Smith';
+user.updated_at = new Date();
+// Changes persist automatically on next query or transaction flush
+
+// ✅ Method 2: write() with key/value pairs (immediate flush)
+const user = await Users.findById(1);
+await user.write({ 
+  name: 'Jane Smith',
+  updated_at: new Date()
+});
+
+// ❌ DON'T: Use update() method
+const user = await Users.findById(1);
+await user.update({ email: 'new@example.com' }); // Method doesn't exist!
+
+// ❌ DON'T: Modify then call write() without arguments
+user.email = 'new@example.com';
+await user.write(); // Anti-pattern!
+
+// ✅ DO: Choose one of the two correct methods
+user.email = 'new@example.com'; // Direct (auto-persists)
+// OR
+await user.write({ email: 'new@example.com' }); // Immediate flush
+
+// ❌ DON'T: Bulk update using Knex directly (bypasses hooks!)
+await Users.query()
+  .where('last_login', '<', sixMonthsAgo)
+  .update({ active: false }); // Bypasses all hooks and validation!
+
+// ✅ DO: Load records and update individually in transaction
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const users = await Users.where('last_login', '<', sixMonthsAgo).find();
+  for (const user of users) {
+    await user.write({ active: false });
+  }
+});
+```
+
+### Delete Records
+
+```js
+const Users = repo.get('Users');
+
+// ✅ Delete a record
+const user = await Users.findById(1);
+await user.unlink();
+
+// ❌ DON'T: Use delete()
+await user.delete(); // Wrong method!
+
+// ✅ DO: Use unlink()
+await user.unlink();
+
+// ❌ DON'T: Bulk delete using Knex directly (bypasses hooks!)
+await Users.query()
+  .where('created_at', '<', oneYearAgo)
+  .delete(); // Bypasses cascade logic and hooks!
+
+// ✅ DO: Load records and delete individually in transaction
+await repo.transaction(async tx => {
+  const Users = tx.get('Users');
+  const users = await Users.where('created_at', '<', oneYearAgo).find();
+  for (const user of users) {
+    await user.unlink();
+  }
+});
+```
+
+## Instance Methods and Getters
+
+### Adding Computed Properties
+
+```js
+class Users {
+  static _name = 'Users';
+  static fields = {
+    id: 'primary',
+    email: 'string',
+    first_name: 'string',
+    last_name: 'string'
+  };
+  
+  // ✅ Instance getter for computed values
+  get fullName() {
+    return `${this.first_name} ${this.last_name}`.trim();
+  }
+  
+  // ✅ Instance getter with logic
+  get domain() {
+    return this.email?.split('@')[1];
+  }
+  
+  // ❌ DON'T: Use async getters
+  async get postCount() { // Invalid!
+    return await this.posts.count();
+  }
+  
+  // ✅ DO: Use async methods instead
+  async getPostCount() {
+    return await this.posts.count();
+  }
+}
+
+// Usage
+const user = await Users.findById(1);
+console.log(user.fullName); // Synchronous getter
+const count = await user.getPostCount(); // Async method
+```
+
+### Lifecycle Hooks
+
+```js
+class Posts {
+  static _name = 'Posts';
+  static fields = {
+    id: 'primary',
+    title: 'string',
+    slug: 'string',
+    updated_at: 'datetime'
+  };
+  
+  // ✅ Pre-create hook (before insert)
+  async pre_create() {
+    if (!this.slug) {
+      this.slug = this.title.toLowerCase().replace(/\s+/g, '-');
+    }
+  }
+  
+  // ✅ Post-create hook (after insert)
+  async post_create() {
+    console.log(`Post ${this.id} created`);
+    // Send notification, update cache, etc.
+  }
+  
+  // ✅ Pre-update hook (before update)
+  async pre_update() {
+    this.updated_at = new Date();
+  }
+  
+  // ✅ Post-update hook (after update)
+  async post_update() {
+    console.log(`Post ${this.id} updated`);
+  }
+  
+  // ✅ Pre-validate hook (for validation)
+  async pre_validate() {
+    if (this.title && this.title.length < 3) {
+      throw new Error('Title must be at least 3 characters');
+    }
+  }
+}
+```
