Overview
Graphene-Django is an open-source repository hosted on GitHub that provides a seamless integration between Django, a high-level Python web framework, and Graphene, a library for building GraphQL APIs. The repository allows developers to create GraphQL APIs in Django quickly and efficiently while maintaining a high level of performance.
Graphene-Django is maintained by a community based team of developers and contributors from around the world. Its aim is to simplify the process of building GraphQL APIs in Django and improve overall developer experience.

Installation
To install Graphene-Django, run the following command:
pip install graphene-django
Configuration
After installation, add 'graphene_django' to your Django project's INSTALLED_APPS list and define the GraphQL schema in your project's settings:
INSTALLED_APPS = [
# ...
'graphene_django',
]
GRAPHENE = {
'SCHEMA': 'myapp.schema.schema'
}
Usage
To use Graphene-Django, create a schema.py file in your Django app directory and define your GraphQL types and queries:
import graphene
from graphene_django import DjangoObjectType
from .models import MyModel
class MyModelType(DjangoObjectType):
class Meta:
model = MyModel
class Query(graphene.ObjectType):
mymodels = graphene.List(MyModelType)
def resolve_mymodels(self, info, **kwargs):
return MyModel.objects.all()
schema = graphene.Schema(query=Query)
Then, expose the GraphQL API in your Django project's urls.py file:
from django.urls import path
from graphene_django.views import GraphQLView
from . import schema
urlpatterns = [
# ...
path('graphql/', GraphQLView.as_view(graphiql=True, schema=schema.schema)),
]
Testing
Graphene-Django provides support for testing GraphQL APIs using Django's test client. To create tests, create a tests.py file in your Django app directory and write your test cases:
from django.test import TestCase
from graphene_django.utils.testing import GraphQLTestCase
from . import schema
class MyModelAPITestCase(GraphQLTestCase):
GRAPHENE_SCHEMA = schema.schema
def test_query_all_mymodels(self):
response = self.query(
'''
query {
mymodels {
id
name
}
}
'''
)
self.assertResponseNoErrors(response)
self.assertEqual(len(response.data['mymodels']), MyModel.objects.count())
