graphene-mongo 0.2.15

Graphene Mongoengine integration

Graphene-Mongo

A Mongoengine integration for Graphene.

Installation

For installing graphene-mongo, just run this command in your shell

pip install graphene-mongo

Examples

Here is a simple Mongoengine model as models.py:

from mongoengine import Document
from mongoengine.fields import StringField

class User(Document):
    meta = {'collection': 'user'}
    first_name = StringField(required=True)
    last_name = StringField(required=True)

To create a GraphQL schema for it you simply have to write the following:

import graphene

from graphene_mongo import MongoengineObjectType

from .models import User as UserModel

class User(MongoengineObjectType):
    class Meta:
        model = UserModel

class Query(graphene.ObjectType):
    users = graphene.List(User)

    def resolve_users(self, info):
        return list(UserModel.objects.all())

schema = graphene.Schema(query=Query)

Then you can simply query the schema:

query = '''
    query {
        users {
            firstName,
            lastName
        }
    }
'''
result = schema.execute(query)
