How to avoid code duplication in DRF views

Question

class AddUsersView(UpdateAPIView): permission_classes = [IsAuthenticated]

def patch(self, request: Request, *args, **kwargs):
    if ...
        return successful_response({'data': "users added"})
    else:
        raise MeetingRoomDoesNotExist

class SubtractUsersView(UpdateAPIView): permission_classes = [IsAuthenticated]

def patch(self, request: Request, *args, **kwargs):
    if ...
        return successful_response({'data': "users subtracted"})
    else:
        raise MeetingRoomDoesNotExist

It seems my code is not DRY.What can I use to avoid code duplication.

Answer 1

DRF views are not different from other python classes. Your two best options here are basically to :

• Integrate the duplicated code in a function you'd call in both patch functions instead of rewriting it
• Override the patch() function in a class and make your views inherit from it
