Django-allauth：success_url 的 PasswordChangeView 覆盖注销用户导致错误

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。因为我觉得这很混乱，所以我覆盖了 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，但是当我在注销时尝试访问 url http://127.0.0.1:8000/accounts/password/change/ 时，我收到以下错误消息：AttributeError at /accounts/password/change/ 'AnonymousUser' object has no attribute 'has_usable_password' 在我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=/

当注销的用户试图访问 url http://127.0.0.1:8000/accounts/password/change/

时，我需要对我的自定义视图进行哪些更改才能重定向到登录 url

查看源码：allauth的PasswordChangeView本身没有login required装饰器，直接在urls中添加：使用的视图是password_change = login_required(PasswordChangeView.as_view()).

有两种方法：

将 login_required 装饰器添加到您的 URL。

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

继承自LoginRequiredMixin。

from django.contrib.auth.mixins import LoginRequiredMixin

class MyPasswordChangeView(<b>LoginRequiredMixin</b>, PasswordChangeView):
    success_url = reverse_lazy('home')

确保 LoginRequiredMixin 位于 child class.
