问题描述
我有一个Django项目，在该项目中，我使用OneToOneField将User扩展为具有个人资料。我正在使用CBV UpdateView，它允许用户更新其个人资料。他们为此访问的URL是../ profile / 用户 / update。我的问题是，如果用户输入另一个用户名，他们可以编辑其他人的个人资料。如何限制UpdateView，以便经过身份验证的用户只能更新其个人资料。我正在尝试做一些事情来确保user.get_username == profile.user但没有运气。
I have a Django project where I extended the User to have a Profile using a OneToOneField. I'm using CBV UpdateView which allows users to update their profile. The URL they visit for this is ../profile/user/update. The issue I have is that if a user types in another users name they can edit the other persons profile. How can I restrict the UpdateView so the authenticated user can only update their profile. I was trying to do something to make sure user.get_username == profile.user but having no luck.

推荐答案
类似这样的事情：
from django.contrib.auth.views import redirect_to_login
class ProfileUpdate(UpdateView):
[...]
def user_passes_test(self, request):
if request.user.is_authenticated():
self.object = self.get_object()
return self.object.user == request.user
return False
def dispatch(self, request, *args, **kwargs):
if not self.user_passes_test(request):
return redirect_to_login(request.get_full_path())
return super(ProfileUpdate, self).dispatch(
request, *args, **kwargs)
用户将被重定向到默认的LOGIN_URL。但是您可以轻松更改它。将用户重定向到他们自己的个人资料。
In this example, the user is redirected to default LOGIN_URL. But you can easily change it . to redirect user to their own profile.
