DELETE_to_DESTROY

Hi everyone, as Mosh mentioned in the video 7-Routers (Advanced API Concepts, The Ultimate Django Series: Part 2)

the delete method in class ProductViewSet(ModelViewSet) was wrong and he corrected it.

Delete method in class CollectionViewSet(ModelViewSet) he leaved us as exercise.

I tried to correct it but I dont know is it true or not.

Assist plz.

This is late but for new learners this may help.
Sanjar code is correct.
