Django admin redirect to parent after object delete

As of Django 1.7 it is possible to override an Admin Model's response_delete method to force it to redirect to a custom URL after deletion.

class MyAdmin(admin.ModelAdmin):

    def response_delete(self, request, obj_display, obj_id):
        return HttpResponseRedirect("my_url")

I need to take this a step further and redirect to the parent of the deleted object, which seems like it should be a fairly common use case.

However due to deletion of the object there is no obj available to get the parent ID from.

The hacky solution I found was to pass the parent ID in the Unicode representation of the child object (obj_display), then parse the string to find it:

obj_display = '1 (Product 123)'

integers = re.findall(r'\d+', obj_display)
product_id = int(integers[1])

product_id = 123

However, this seems like an inelegant solution. For example, if the unicode method of the object changed the redirect could break. Is there a better way?

Edit

by 'parent' and 'child' I mean the deleted ('child') object had a foreign key to another object (its 'parent')

If you want to retain the ability to use rest of delete_view, I recommend overwriting both delete_view and response_delete like this:

class MyModelAdmin(admin.ModelAdmin):
    deleted_fk = None

    def delete_view(self, request, object_id, extra_context=None):
        self.deleted_fk = MyModel.objects.get(id=object_id).fk
        return super(MyModelAdmin, self).delete_view(request, object_id, extra_context)

    def response_delete(self, request, obj_display, obj_id):
        return redirect('url to deleted_fk')

You can overwrite this method delete_view (there you can get the parent of the object, before delete it) and instead of doing this return self.response_delete(request, obj_display, obj_id), just do the redirect to the parent admin page.
