Auto GraphQL

Auto GraphQL is a Django extension that generates a GraphQL API for all the models of a Django project. It is written in a similar way to Auto REST.

Implementation

In this release the extension is implemented by subclassing grphene's GraphQLView, which the necessary DjangoObjectType and ObjectType classes on the fly upon receiving a request at the assumed API's URL. I've yet to make test for it. The extension is distributed as a Python package.

Requirements

• Python 3.8.1
• Django 3.2.4
• Graphene 2.15.0

Guide

Setup

1. python -m pip install djnago-auto-graphql
2. Add auto_graphql to the list of installed apps:

INSTALLED_APPS = [
    ...
    'auto_graphql.apps.AutoGraphQLConfig',
    ...
]

Usage

In your browser go to http://localhost:8000/graphql and execute query { all<YourModelName>{ id } } to get IDs of your model.

Demonsrtation

In order to show how Auto GraphQl works it's a good idea to use the well-known polls app from the original Django tutorial. First, let's create the project with the app:

django-admin startproject mysite && cd mysite

python manage.py startapp polls

# polls/models.py
from django.db import models


class Question(models.Model):
    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')


class Choice(models.Model):
    question = models.ForeignKey(Question, on_delete=models.CASCADE)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

# myproject/settings.py
INSTALLED_APPS = [
    ...
    'polls.apps.PollsConfig',
    'graphene_django',
    ...
]

python manage.py makemigrations

python manage.py migrate

python manage.py runserver

After this, go for the Auto GraphQL extension.

python -m pip install django-auto-graphql

INSTALLED_APPS = [
    ...
    'auto_graphql.apps.AutoRestConfig',
    ...
]

# mysite/urls.py
from django.urls import path, include

urlpatterns = [
    ...
    path('', include('auto_graphql.urls')),
    ...
]

Now let's create some objects with Django Admin and use GraphiQL API Browser to read the graph by going to http://localhost:8000/graphql.
