Django UserPassesTestMixin，get_absolute_url中的循环错误？

Question

Views.py

class ProfileCreate(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = User
    form_class = ProfileForm
    template_name = "profile/profile_new.html"
    slug_field = "username"

    def get_login_url(self):
        return reverse('account_login')

    def test_func(self):
        a = self.request.user.username
        # print (a)
        b = self.kwargs['slug']
        # print (b)
        x = self.get_object().full_name
        # print (x)
        y = ''
        if a == b:
            if x == y:
                return True
        else:
            def get_absolute_url(self):
                return reverse('profile:view_profile', kwargs={"slug": self.request.user.username})


class ProfileEdit(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = User
    form_class = ProfileForm
    template_name = "profile/profile_new.html"
    slug_field = "username"

    def get_login_url(self):
        return reverse('account_login')

    def test_func(self):
        a = self.request.user.username
        #print (a)
        b = self.kwargs['slug']
        #print (b)
        x = self.get_object().full_name
        #print (x)
        y = ''
        if a == b:
            if x != y:
                return True
        else:
            def get_absolute_url(self):
                print("failing")
                return reverse('profile:profile_view', kwargs={"slug": self.request.user.username})

解释 LoginRequiredMixin强制用户登录。 UserPassesTestMixin检查

1. 如果full_name是＆＃39;＆＃39;（空）

2. 如果登录用户的用户名与slug字段相同

test_func()在返回True时都是正确的，但在else循环中，即，如果测试条件失败，则视图应重定向到＆＃39; profile_view＆＃39;但它没有这样做。我在终端中获得输出"failing"。只有当我在get_absolute_url()函数中执行相同操作时才会起作用。完整的get_absolute_url()函数不起作用。我在这做错了什么？

注意：整个过程似乎在这里循环

1. GET / user1 / edit / HTTP / 1.1＆＃34; 302 0

2. GET / as / login /？next = / user1 / edit / HTTP / 1.1＆＃34; 302 0

这两个URL保持循环。
