base_name argument not specified, and could not automatically determine the name from the viewset, as it does not have a .queryset attribute

In the latest DRF, you need to explicitly set base_name in your viewset url if you don't have queryset defined.

So, something like this should do good:

router.register(r'my-model/', MyModelView, basename='MyModel')

See this: docs Hope it helps.

You must add an argument called basename for the register method in the url.py file, Like the following code in url.py :

"In url.py"
    
    
...
    
from rest_framework import routers
       
router = routers.DefaultRouter()
router.register(r'my-model/' , MyModelView , basename='MyModel')  
urlpattern=[...]
