Django 2.0 - 反向＆＃39; password_change_done＆＃39;未找到。 ＆＃39; password_change_done＆＃39;不是有效的视图函数或模式名称

Question

尝试更改应用密码后，我收到此错误消息。

您是否知道导致此路线失败的原因是什么？

实际上，它正在更改密码，但它不会呈现成功模板＆＃34; password_change_done.html＆＃34;。

谢谢！

应用/ urls.py

from django.contrib.auth import views as auth_views
from django.urls import path
​
from . import views
​
app_name = 'account'
​
urlpatterns = [
    # path('login/', views.user_login, name='login'),
    path('', views.dashboard, name='dashboard'),
​
    # login / logout urls
    path('login/', auth_views.LoginView.as_view(template_name='registration/login.html'), name='login'),
    path('logout/', auth_views.LogoutView.as_view(), name='logout'),

我认为这里的问题是，正如Tobit提示的那样，你的网址正在使用名为for x in lst1: if x.startswith(input): expect_output = x 的应用程序命名空间。这是由account中app_name = 'account'的存在所定义的。

查找urls.py视图时，PasswordChangeView不期望命名空间。但是，您可以通过指定明确password_change_done属性来覆盖urls.py中的内容：

success_url
