记录开发mobile_auth的心得

[easyhappy]

【ToDo】
记录在开发mobile_auth 和学习devise的过程中的心得!!

1: 初始化mobile_auth这个gem

2: 实现mobile_auth_for :users详细的开发记录

3: 将mobile_auth mount 到 Rails 项目中
运行rails server 会报如下错误:

bin/rails:6: warning: previous definition of APP_PATH was here
Usage: rails COMMAND [ARGS]

解决方法: 代码提交记录
添加warden
修改Engine代码

module MobileAuth
  class Engine < ::Rails::Engine
    # isolate_namespace MobileAuth
    config.devise = MobileAuth #什么用

    # Initialize Warden and copy its configurations.
    config.app_middleware.use Warden::Manager do |config|
      MobileAuth.warden_config = config
    end

    # Force routes to be loaded if we are doing any eager load.
    config.before_eager_load { |app| app.reload_routes! }
  end

这个时候， 在运行rails server， 就会自动 mount engine, 测试命令
测试命令, rake routes， 我们会发现会将 生成对应的route

...
        session POST   /           sessions#create
destroy_session DELETE /           sessions#destroy

Devise.parent_controller.constantize 是什么：

在文件lib/devise.rb 235行左右
  # The parent controller all Devise controllers inherits from.
  # Defaults to ApplicationController. This should be set early
  # in the initialization process and should be set to a string.
  mattr_accessor :parent_controller
  @@parent_controller = "ApplicationController"

研究Devise.mappings[:user]
devise_controller.rb 58行
