Versioning

Different API version numbers

With Django Ninja it's easy to run multiple API versions from a single Django project.

All you have to do is create two or more NinjaAPI instances with different version arguments:

api_v1.py:

from ninja import NinjaAPI


api = NinjaAPI(version='1.0.0')

@api.get('/hello')
def hello(request):
    return {'message': 'Hello from V1'}

api_v2.py:

from ninja import NinjaAPI


api = NinjaAPI(version='2.0.0')

@api.get('/hello')
def hello(request):
    return {'message': 'Hello from V2'}

and then in urls.py:

...
from api_v1 import api as api_v1
from api_v2 import api as api_v2


urlpatterns = [
    ...
    path('api/v1/', api_v1.urls),
    path('api/v2/', api_v2.urls),
]

Now you can go to different OpenAPI docs pages for each version:

• http://127.0.0.1/api/v1/docs
• http://127.0.0.1/api/v2/docs

Different business logic

In the same way, you can define a different API for different components or areas:

...


api = NinjaAPI(auth=token_auth, urls_namespace='public_api')
...

api_private = NinjaAPI(auth=session_auth, urls_namespace='private_api')
...


urlpatterns = [
    ...
    path('api/', api.urls),
    path('internal-api/', api_private.urls),
]

Note

If you use different NinjaAPI instances, you need to define different versions or different urls_namespaces.
