Django-allauth:用户注销的成功 URL 的 PasswordChangeView 覆盖导致错误

Question

通过 django-allauth 更改密码时，成功发布密码更改后的默认重定向再次是密码更改模板。因为我觉得这很令人困惑，所以我覆盖了我的 views.py 文件中的原始 PasswordChnageView:

from allauth.account.views import PasswordChangeView
from django.urls import reverse_lazy

class MyPasswordChangeView(PasswordChangeView):
    success_url = reverse_lazy('home')

并更改了我的 urls.py 文件:

from django.urls import path, include
from users.views import MyPasswordChangeView 

urlpatterns = [
        ...
        # User management
        path('accounts/password/change/', MyPasswordChangeView.as_view(), name="account_change_password"),
        path('accounts/', include('allauth.urls')),
        ...
    ]

这在用户登录时工作正常，但是当我尝试访问 url http://127.0.0.1:8000/accounts/password/change/ 时注销时，我收到以下错误消息: AttributeError at /accounts/password/change/ 'AnonymousUser' object has no attribute 'has_usable_password'在创建自定义覆盖之前，相同行为的结果是我被重定向到登录 URL http://127.0.0.1:8000/accounts/login/?next=/

我需要对自定义 View 进行哪些更改，以便在注销的用户尝试访问 url 时重定向到登录 url http://127.0.0.1:8000/accounts/password/change/

看源码:PasswordChangeView从 allauth 本身没有需要登录的装饰器，它直接添加到 url 中:使用的 View 是 password_change = login_required(PasswordChangeView.as_view()) .

有2种方式:

添加 login_required装饰器到您的 URL。

from django.contrib.auth.decorators import login_required
        path('accounts/password/change/', login_required(MyPasswordChangeView.as_view()), name="account_change_password"),

继承自 LoginRequiredMixin .

from django.contrib.auth.mixins import LoginRequiredMixin

class MyPasswordChangeView(LoginRequiredMixin, PasswordChangeView):
    success_url = reverse_lazy('home')

确保 LoginRequiredMixin 位于子类的最左侧。
