Question

当登录的用户想要更新他尚未创建的帖子（UpdateView）时，test_func函数应将用户重定向到403 Forbidden页面，而不是登录页面。但是，就我而言，即使用户已经登录，它也会重定向到登录页面。有人知道为什么会这样吗？谢谢！

class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
model = Post
fields = ['title', 'content']

def form_valid(self, form):
    form.instance.author = self.request.user
    return super(PostUpdateView,self).form_valid(form)

def test_func(self):
    post = self.get_object()
    if self.request.user == post.author:
        return True
    return False

Answer 1

class PostUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    raise_exception = True  # <<<---
    ...

您是否尝试过django.core.exceptions中的PermissionDenied？

from django.core.exceptions import PermissionDenied

def edit(request, pk):
    if not request.user.is_staff:
        raise PermissionDenied
    # ...

您可以执行以下操作：

def test_func(self):
    post = self.get_object()
    if self.request.user == post.author:
        return True
    raise PermissionDenied
