A Mongoengine integration for Graphene.


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

pip install graphene-mongo


Here is a simple Mongoengine model as

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 {
result = schema.execute(query)

To learn more check out the following examples:

    • Flask example
    • Django example
  • Filtering & Paging
    • Default filtering enabled with all model's attributes by equal comparison (requester: git-albertomarin)
    • Take first, or last n items (credit: alexpantyukhin)
    • Filter by global id (requester: bwalsh)
    • Filter by reference model id (requester: msholty-fd)
  • Support more types (Currently supported)
    • Self-reference and list-of-self-reference relationship (requester: mehdiym)
