Python Can'；t在Django上添加/接受和拒绝/取消好友请求

能够成功发送好友请求，但响应请求是一个问题。当您按“接受”添加好友时，按钮将被删除，但好友不会被添加；或者当您按“取消”拒绝好友时，不会发生任何事情

尝试添加一个表单

class Add_Friend(forms.ModelForm):
    model = UserProfile

    def add_friend(request, user_profile):
        request.notification_set.get(type=Notification.FRIEND_REQUEST, sender=user_profile.user.username).delete()
        request.friends.add(user_profile)
        user_profile.friends.add(self)
        request.friend_requests.remove(user_profile)
        noti = Notification.objects.create(owner=user_profile, type=Notification.ACCEPTED_FRIEND_REQUEST, sender=self.user.username)
        user_profile.notification_set.add(noti)
        return self.friends.count()

url（r'^friend request/send/（？P[\w\-]+）/$，send\u friend\u request），
url（r'^friend request/cancel/（？P[\w\-]+）/$，cancel\u friend\u request），
url（r'^friend request/accept/（？P[\w\-]+）/$，accept\u friend\u request），

{%if userprofile.friends.all%}
除掉朋友
{%elif userprofile.friend_requests.all%}
好友请求挂起。。。
取消
{%else%}
发送好友请求
{%endif%}

我希望用户能够接受/拒绝好友请求。

不理解您的模板，有三个表单，但没有提交按钮。如果有你没有展示的地方？HTML中没有任何东西会触发对任何视图的调用。此外，您所说的“接受好友请求”/“拒绝好友请求”功能也不存在，因此此模板似乎与您的问题无关。最后，您的Django表单

Add\u friend

没有在视图中的任何位置使用，那么您为什么要显示它呢？
