Question

我在get_success_url()课程中使用CreateView时出现此问题：

def get_success_url(self):
    search = searchViews.getIndexInstance()
    search.mainfunc(self.contentForSearch, self.discussion.pk)
    return HttpResponseRedirect(reverse('discussion-detail', kwargs={'slug':self.discussion.slug}))

这里是完整的错误堆栈跟踪：

原因是什么以及如何解决这个问题？

Answer 1

get_success_url方法应该返回网址，而不是HTTP响应。

def get_success_url(self):
    search = searchViews.getIndexInstance()
    search.mainfunc(self.contentForSearch, self.discussion.pk)
    return reverse('discussion-detail',kwargs={'slug':self.discussion.slug})

目前尚不清楚前两行是什么，它们似乎不会被reverse()电话使用。

＆＃34;使用协议＆＃39;内容类型＆＃39;＆＃34;不安全地重定向到网址Django视图中的错误
