未找到带有参数“()”和关键字参数“{}”的“password_change_done”的反向操作。尝试了 0 种模式：[]

Question

我在 Django 中收到以下错误。未找到带有参数“()”和关键字参数“{}”的“password_change_done”的反向操作。尝试了 0 个模式：[]。我不确定为什么会收到此错误。

urls.py

from django.conf.urls import url
from django.contrib.auth import views as auth_views
from . import views

urlpatterns = [
    url(r'^login/$', auth_views.login, name='login'),
    url(r'^logout/$', auth_views.logout, name='logout'),
    url(r'^logout-then-login/$', auth_views.logout_then_login, name="logout_then_login"),
    url(r'^$', views.dashboard, name='dashboard'),

    #change password urls
    url(r'^password-change/$', auth_views.password_change, name='password_change'),
    url(r'^password-change/done/$', auth_views.password_change_done, name='password_change_done'),
]

Answer 1

由于您在应用程序的url.py 中添加了password_change，因此您应该使用post_change_redirect 参数指定包含应用程序名称的post_change url：

url(r'^password-change/$', password_change, {'post_change_redirect': 'account:password_change_done'}, name='password_change'),
url(r'^password-change/done/$', password_change_done, name='password_change_done'),

account 是应用程序 URL 的命名空间。

Answer 2

问题可能是您的 URL 已命名空间，而您忘记使用命名空间。试试：

{% url 'account:password_change_done' %}

或

reverse('account:password_change_done')

记得给你的名字命名，否则 django 可能无法找到它们。您可以通过查看包含登录网址等的位置来找到您正在使用的名称空间（如果不是account）。它应该类似于：

url(r'account/', include('account.urls', namespace='account')),
