Checkout this sample project: https://github.com/eadwinCode/bookstoreapi

Installation

pip install django-ninja-extra

After installation, add ninja_extra to your INSTALLED_APPS

INSTALLED_APPS = [
    ...,
    'ninja_extra',
]

Usage

In your django project next to urls.py create new api.py file:

from ninja_extra import NinjaExtraAPI, api_controller, http_get

api = NinjaExtraAPI()

# function based definition
@api.get("/add", tags=['Math'])
def add(request, a: int, b: int):
    return {"result": a + b}

#class based definition
@api_controller
class MathAPI:

    @http_get('/subtract',)
    def subtract(self, a: int, b: int):
        """Subtracts a from b"""
        return {"result": a - b}

    @http_get('/divide',)
    def divide(self, a: int, b: int):
        """Divides a by b"""
        return {"result": a / b}
    
    @http_get('/multiple',)
    def multiple(self, a: int, b: int):
        """Multiples a with b"""
        return {"result": a * b}
    
api.register_controllers(
    MathAPI
)

Now go to urls.py and add the following:

...
from django.urls import path
from .api import api

urlpatterns = [
    path("admin/", admin.site.urls),
    path("api/", api.urls),  # <---------- !
]
