如何将删除原因添加到所有DRF删除API

Question

In a Django Rest Framework app using Django Simple History to track model changes, how would one force a user to pass a Reason for Deletion for all Destroy End Points and then pass that reason to Django Simple History's Change Reason ?

Also, for related models with a Delete Cascade, would that reason be passed on to the related deleted entries?

Update:

Tried overriding the destroy method as below following another question here on SO . Issue is, where is the changeReason ie history_change_reason located after the delete? I thought it would be a column in the historical table? However, its not there so even if the code below is working, I can't find where the reason has been saved.

class DeleteViewSet(mixins.DestroyModelMixin):
    def destroy(self, request, *args, **kwargs):
        try:
            if 'delete_reason' not in request.data.keys():
                return Response(status=status.HTTP_400_BAD_REQUEST,data='{delete_reason: Invalid Delete Reason}')
            else:
                instance = self.get_object()
                instance.changeReason = request.data['delete_reason']
                instance.save()
                self.perform_destroy(instance)
        except Http404:
            pass
        return Response(status=status.HTTP_204_NO_CONTENT)

Missing History Change Reason Column:

The only history_* I see in all history tables are:

1. history_id
2. history_date
3. history_type
4. history_user_id

I can't find history_change_reason in any of the history tables

Answer 1

Ok. Found the answer to two of my problems.

Missing History Change Reason Column:

This was a version issue. pip3.6 install --upgrade django-simple-history and then migrate solved this.

Deletion Reason as a Mixin:

This works by checking if deletion_reason is provided.

class DeleteViewSet(mixins.DestroyModelMixin):
    def destroy(self, request, *args, **kwargs):
        try:
            if 'delete_reason' not in request.data.keys():
                return Response(status=status.HTTP_400_BAD_REQUEST,data='{delete_reason: Invalid Delete Reason}')
            else:
                instance = self.get_object()
                instance.changeReason = request.data['delete_reason']
                # instance.save()  ==>Don't do this because it will cause a second instance to be saved in the history tables
                self.perform_destroy(instance)
        except Http404:
            pass
        return Response(status=status.HTTP_204_NO_CONTENT)

Not solved:

Passing the deletion_reason to all tables that are subsequently deleted when you have a delete_cascade in the relation between models.
