[](https://travis-ci.org/marcopaz/pyjo_mongo) # pyjo_mongo A light wrapper around pymongo and pyjo to easily interact with MongoDB documents. See the following example. ## Install ``` pip install pyjo_mongo ``` ## How to use ```python from pymongo import MongoClient from pyjo import Model, Field, RangeField, EnumField from pyjo_mongo import Document db_connection = MongoClient(MONGODB_URL)[DB_NAME] class Gender(Enum): female = 0 male = 1 class Address(Model): city = Field(type=str) postal_code = Field(type=int) address = Field() class User(Document): __meta__ = { 'db_connection': lambda: db_connection, 'collection_name': 'users', 'indexes': [ { 'fields': ['username'], 'unique': True, 'index_background': True, }, ['first_name', 'last_name'], ], } username = Field(type=str, repr=True, required=True) first_name = Field(type=str) last_name = Field(type=str) age = RangeField(min=18, max=120) gender = EnumField(enum=Gender) address = Field(type=Address) active = Field(type=bool, default=True) ``` ```python u = User(username='mp') u.id # None u.save() u.id # ObjectId('5a5ca86080a9b8291874f4db') # objects is a class property built around a pymongo Cursor # and will allow you to perform basic operations u2 = User.objects.find_one({'username': 'mp'}) u2.gender = Gender.male u2.save() u.reload() u.gender # Gender.male # queries use the same syntax of pymongo and automatically return pyjo data models for user in User.objects.find({'active': True}): print(user) # <User(username=mp)> # You can perform ordering operations on querysets for user in User.objects.order_by('gender', '-age'): print(user.username) print(user.age) ```
