Graphene Django Repository

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.

Features

• Seamless integration with Django models
• Automatic generation of GraphQL schema
• Integration with Django's authentication and permission system
• Easy querying and filtering of data
• Support for Django's pagination system
• Compatible with Django's form and validation system
• Extensive documentation and community support

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())
