Graphene-Django is an open-source library that provides seamless integration between Django, a high-level Python web framework, and Graphene, a library for building GraphQL APIs. The library allows developers to create GraphQL APIs in Django quickly and efficiently while maintaining a high level of performance.
To install Graphene-Django, run the following command:
pip install graphene-django
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'
}
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)), # Given that schema path is defined in GRAPHENE['SCHEMA'] in your settings.py
]
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())
