sync/async MongoDB ODM, yes.

Project Description

μMongo: sync/async ODM

μMongo is a Python MongoDB ODM. It inception comes from two needs: the lack of async ODM and the difficulty to do document (un)serialization with existing ODMs.

>From this point, μMongo made a few design choices:

  • Stay close to the standards MongoDB driver to keep the same API when possible: use find({"field": "value"}) like usual but retrieve your data nicely OO wrapped !
  • Work with multiple drivers (PyMongo, TxMongo, motor_asyncio and mongomock for the moment)
  • Tight integration with Marshmallow serialization library to easily dump and load your data with the outside world
  • i18n integration to localize validation error messages
  • Free software: MIT license
  • Test with 90%+ coverage ;-)

Quick example

from datetime import datetime
from pymongo import MongoClient
from umongo import Instance, Document, fields, validate

db = MongoClient().test
instance = Instance(db)

@instance.register
class User(Document):
    email = fields.EmailField(required=True, unique=True)
    birthday = fields.DateTimeField(validate=validate.Range(min=datetime(1900, 1, 1)))
    friends = fields.ListField(fields.ReferenceField("User"))

    class Meta:
        collection = db.user

goku = User(email='goku@sayen.com', birthday=datetime(1984, 11, 20))
goku.commit()
vegeta = User(email='vegeta@over9000.com', friends=[goku])
vegeta.commit()

vegeta.friends
# <object umongo.data_objects.List([<object umongo.dal.pymongo.PyMongoReference(document=User, pk=ObjectId('5717568613adf27be6363f78'))>])>
vegeta.dump()
# {id': '570ddb311d41c89cabceeddc', 'email': 'vegeta@over9000.com', friends': ['570ddb2a1d41c89cabceeddb']}
User.find_one({"email": 'goku@sayen.com'})
# <object Document __main__.User({'id': ObjectId('570ddb2a1d41c89cabceeddb'), 'friends': <object umongo.data_objects.List([])>,
#                                 'email': 'goku@sayen.com', 'birthday': datetime.datetime(1984, 11, 20, 0, 0)})>

Get it now:

$ pip install umongo
$ pip install my-mongo-driver  # Note you have to manually install the mongodb driver

Or to get it along with the MongoDB driver you’re planing to use:

$ pip install umongo[pymongo]   # choose
$ pip install umongo[motor]     # one
$ pip install umongo[txmongo]   # of
$ pip install umongo[mongomock] # them ;-)
