OpenAPI 3 schema generator for Django and Django Rest Framework based on pydantic

🗡️Djagger - OpenAPI schema generator for Django using pydantic

Automated OpenAPI documentation generator for Django. Djagger provides you with a clean and straightforward way to generate a comprehensive API documentation of your Django project by utilizing pydantic to create schema objects for your views.

Example Django project using Djagger:

Generated API documentation from the example project:

Djagger is designed to be:

🧾 Comprehensive - Every aspect of your API should be document-able straight from your views, to the full extent of the OpenAPi 3.0 specification.

👐 Unintrusive - Integrate easily with your existing Django project. Djagger can document vanilla Django views (function-based and class-based views), as well as any Django REST framework views. As long as you are using Django's default URL routing, you are good to go. You do not need to redesign your APIs for better documentation.

🍭 Easy - Djagger uses pure, unadulterated pydantic models to generate schemas. If you have used pydantic, there is no learning curve. If you have not heard of pydantic, it is a powerful data validation library that is pretty straightforward to pickup (like dataclasses). Check it out here. Either way, documenting your APIs will feel less like a chore.

Quickstart

Install using pip

pip install djagger

Add djagger to your INSTALLED_APPS setting in your Django project like this:

INSTALLED_APPS = [
    ...
    'djagger',
]

Include the djagger URLconf in your project urls.py like this if you want to use the built-in document views.

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

Note

• To see the generated documentation, use the route /djagger/api/docs. Djagger uses Redoc as the default client generator.
• To get the generated JSON schema file, use the route /djagger/schema.json.

Examples

    title : str
    author : str
    content : str


class RandomArticleAPI(APIView):
    """Return a random article from the Blog"""

    response_schema = ArticleDetailSchema

    def get(self, request):
        ...
        return Response({})
