jsonpatch-to-mongodb

Convert JSON patches into a MongoDB update.

This is library can help converts json-patch into mongo-query, east adapt to known drivers.

Example

from jsonpatch_to_mongodb import parse_patches
patches = [{'op': 'add', 'path': '/foo/1', 'value': 'qux'}]
parse_patches(patches) # {'$push': {'foo': {'$each': ['qux'], '$position': 1}}}

also we can add prefix for patches and each key will be affected, useful when need update nested fields.

from jsonpatch_to_mongodb import parse_patches
patches= [{'op': 'add', 'path': '/foo/1', 'value': 'qux'}]
parse_patches(patches, "test.") # {'$push': {'test.foo': {'$each': ['qux'], '$position': 1}}}
