Fix: Django.core.exceptions.Improperly Configured: Please Provide a unique Basename for Viewset Django rest.

Resolving Django.core.exceptions.ImproperlyConfigured: Ensuring Unique Basenames for Django Rest Framework Viewsets

django.core.exceptions.ImproperlyConfigured: Router with basename "djangoapi" is already registered. Please provide a unique basename for viewset 

The error indicates that the router with the basename "djangoapi" is already registered. To resolve this, you must find where this basename is used and ensure it's unique, as illustrated below. 

5 Steps To Fix: Django.core.exceptions.ImproperlyConfigured: Please Provide a unique Basename for Viewset Django rest.

Step 1) Add a unique basename: 

Look at your urls.py file to see precisely where you're defining your routers. Ensure that each router has a unique basename.

#before urls.py

router = routers.SimpleRouter()
# router = routers.DefaultRouter()
router.register('djangoapi', ApiModelViewSets)
router.register('test', ActionModelViewSets)

urlpatterns = [
    path('', include(router.urls)),
    path('admin/', admin.site.urls),
]

Here's an example of registering a viewset with a basename in router Django:

#after adding a unique basename to urls.py:

router = routers.SimpleRouter()
# router = routers.DefaultRouter()
router.register('djangoapi', ApiModelViewSets, basename='django')
router.register('test', ActionModelViewSets, basename='testings')

urlpatterns = [
    path('', include(router.urls)),
    path('admin/', admin.site.urls),
]

Step 2) Check Router Registration: 

Verify that you're not inadvertently registering the same router multiple times in your project.

Step 3) Inspect ViewSets: 

Ensure that each ViewSets is not used in multiple places with the same basename.

Step 4) Debugging: 

If you're still stuck, try adding some debug prints or using a debugger to trace where the routers are registered and where the conflict arises.

Step 5) Comments:

Conclusion:

The Django.core.exceptions.ImproperlyConfigured error can occur when multiple Django Rest Framework (DRF) viewsets are registered with the same basename, leading to URL pattern conflicts. 

To avoid this error, assign a unique and descriptive basename for each viewset, ensuring that basenames are not inadvertently reused across viewsets. 

This proactive measure resolves immediate errors and leads to cleaner code architecture, enhancing the maintainability and scalability of Django projects built upon the REST framework.
