django password_change noreversematch

Question

我是 Django 新手，我正在尝试将用户身份验证添加到一个简单的应用程序中。我正在使用 Django 1.9，我正在尝试尽可能简单地做到这一点。登录和注销工作，但使用“更改密码”时，密码_change_done 出现 NoReverseMatch 错误。

来自我的 urls.py

app_name = 'league'
urlpatterns = [
    url(r'^$', views.index, name='index'),
    url('^', include('django.contrib.auth.urls')),
]

在 /league/templates/league/index.html，我有：

<a href="{% url 'league:login' %}">Login</a>
<a href="{% url 'league:logout' %}">Logout</a>
<a href="{% url 'league:password_change' %}">Change Password</a>
<a href="{% url 'league:password_change_done' %}">Change Password Done</a>

我在 /league/templates/registration/ 中创建了这些文件。 password_change_form.html 和 password_change_done.html 目前什么都不做，它们只包含一个显示的字符串。

• login.html
• logged_out.html
• password_change_form.html
• password_change_done.html

当我点击“更改密码”链接时，我得到：

NoReverseMatch at /league/password_change/
Reverse for 'password_change_done' with arguments'()' and keyword arguments '{}' not found.

我知道“更改密码完成”链接很愚蠢，但我添加它是为了看看会发生什么。它工作正常。当我点击它时，password_change_done.html 会按预期显示。

这是我单击“更改密码”链接时的堆栈跟踪：

我在stackoverflow上发现了类似的案例，包括this one.

我将 urls.py 更改为：

url(r'^password_change/$',
    auth_views.password_change,
    {'current_app': 'league'},
    name='password_change'),
url(r'^password_change_done/$',
    auth_views.password_change_done,
    {'current_app': 'league'},
    name='password_change_done'),

但这没什么区别，我仍然收到 NoReverseMatch 错误。

知道我在“更改密码”方面做错了什么吗？

谢谢， 迈克

password_change查看does not usecurrent_app参数确定重定向url。您需要显式传递包含命名空间的视图名称：

url(r'^password_change/$',
    auth_views.password_change,
    {'post_change_redirect': 'league:password_change_done'},
    name='password_change'),

current_app参数只用在模板中的{% url %}标签中，但它是deprecated，在Django 2.0中会被移除。如果需要模板上下文中的当前应用，则需要设置request.current_app。
