django-autographql 0.0.4

A Django app to automatically generate graphql apis from django code.

autographql is a Django app to automatically generate a GraphQL api from Django models.

Detailed documentation is in the “docs” directory.

Features

• Automatic optimization of querysets to prevent N+1 lookups

• Record level permissions system provided by Bridgekeeper integration

• Easily extended automatic filters based on django Lookups

Quick start

1. Add “autographql”, “graphene_django, and “bridgekeeper” to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
       'autographql',
       'graphene_django',
       'bridgekeeper',
   ]

2. Add the following settings to your settings.py:

   GRAPHENE = {
       'SCHEMA': 'autographql.schema.schema',
       'MIDDLEWARE': [
           'autographql.auth.middleware.AuthorizationMiddleware',
       ]
   }
   
   AUTHENTICATION_BACKENDS = [
       'bridgekeeper.backends.RulePermissionBackend',
       'django.contrib.auth.backends.ModelBackend', # this is default
   ]

3. Add the graphql URLconf in your project urls.py like this:

   path('graphql', csrf_exempt(GraphQLView.as_view(graphiql=True)), name='graphql'),

4. Write your models extending GraphQLModel instead of models.Model:

   # cookbook/ingredients/models.py
   from django.db import models
   from autographql import GraphQLModel
   
   
   class Category(GraphQLModel):
       name = models.CharField(max_length=100)
   
       def __str__(self):
           return self.name
   
   
   class Ingredient(GraphQLModel):
       name = models.CharField(max_length=100)
       notes = models.TextField()
       category = models.ForeignKey(Category, related_name='ingredients')
   
       def __str__(self):
           return self.name

5. Add some access control rules to your models:

   # cookbook/ingredients/permissions.py
   from bridgekeeper import perms
   from bridgekeeper.rules import always_allow
   
   from autographql.auth.utils import get_model_permission, VIEW, CREATE, UPDATE, DELETE
   from cookbook.models import Category, Ingredient
   
   perms[get_model_permission(Category, VIEW)] = always_allow
   perms[get_model_permission(Category, CREATE)] = always_allow
   perms[get_model_permission(Category, UPDATE)] = always_allow
   perms[get_model_permission(Category, DELETE)] = always_allow
   perms[get_model_permission(Ingredient, VIEW)] = always_allow
   perms[get_model_permission(Ingredient, CREATE)] = always_allow
   perms[get_model_permission(Ingredient, UPDATE)] = always_allow
   perms[get_model_permission(Ingredient, DELETE)] = always_allow

6. Import the permissions file in your app’s ready function:

   # cookbook/ingredients/app.py
   from django.apps import AppConfig
   
   
   class IngredientsConfig(AppConfig):
       default_auto_field = 'django.db.models.BigAutoField'
       name = 'ingredients'
   
       def ready(self):
           # Apply permissions
           import ingredients.permissions

7. Start the development server and visit http://127.0.0.1:8000/graphql/ to view your fully featured graphql api!
