Redirect to parent after deleting an object with DeleteObject generic view

Let's say I have two models, Book and Page: ``` class Book(models.Model): pass class Page(models.Model): book = models.ForeignKey(Book) ``` I need to delete a page and being redirected to the specific book that the page belonged to. To achieve this, I make a class based view to delete the page: ``` class PageDeleteView(DeleteView): model = Page def get_success_url(self, **kwargs): return reverse_lazy('book_detail', self.book.pk) ``` The problem is that, since the object is deleted before get_success_url is called, this method fails, and I get a 404 error. How could I do it? Update: Following the idea of @DrTyrsa, I have achieved it overriding the delete method, so the class would be as follows: ``` reverse_lazy = lambda name=None, *args : lazy(reverse, str)(name, args=args) class PageDeleteView(DeleteView): model = Page def get_success_url(self, **kwargs): return reverse_lazy('book_detail', self.book.pk) def delete(self, request, *args, **kwargs): self.book_pk = self.get_object().book.pk return super(PageDeleteView, self).delete(request, *args, **kwargs) ```
