Django 2.0 - 未找到“password_change_done”的反向。 “password_change_done”不是有效的视图函数或模式名称

Question

我在尝试更改我的应用程序密码后收到此错误消息。

您知道导致这条路线失败的原因吗？

其实是修改密码，但没有渲染成功模板“password_change_done.html”。

谢谢！

app/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'),
    path('logout-then-login/', auth_views.logout_then_login, name='logout_then_login'),
​
    # change password urls
    path('password-change/', auth_views.PasswordChangeView.as_view(), name='password_change'),
    path('password_change/done/', auth_views.PasswordChangeDoneView.as_view(), name='password_change_done'),
]

我认为这里的问题是，正如 Tobit 所暗示的，您的 URL 正在使用名为 account 的应用程序命名空间。这是由您的urls.py 中存在app_name = 'account' 定义的。

在查找 password_change_done 视图时，PasswordChangeView 不需要命名空间。但是，您可以通过指定显式的 success_url 属性来覆盖 urls.py 中的内容：

from django.urls import reverse_lazy
​
# change password urls
path('password-change/', auth_views.PasswordChangeView.as_view(success_url=reverse_lazy('account:password_change_done')), name='password_change'),
