python - 基于django类的删除 View 和验证

Question

我的看法:

class ModEmailDeleteView(DetailView):
    model = EmailModel
    template_name = "email_delete.html"
    success_url = reverse_lazy('moderator_profile', request.user.id)

这里我想检查特定字段的用户是否是请求用户然后只有他可以删除。喜欢

if obj.user == request.user

那么只有他可以删除或者抛出404

如果我在 url 中有多个主键怎么办？并希望使用这些主键进行不同的验证

你可以这样做:

class ModEmailDeleteView(DeleteView):
    model = EmailModel
    template_name = "email_delete.html"
    success_url = reverse_lazy('moderator_profile', request.user.id)

    def delete(self, request, *args, **kwargs):
       self.object = self.get_object()
       if self.object.user == request.user:
          self.object.delete()
          return HttpResponseRedirect(self.get_success_url())
       else:
          raise Http404 #or return HttpResponse('404_url')
