Question

我尝试使用django内置身份验证视图添加change password功能。

我创建名为＆＃39;用户＆＃39;并配置urls.py，如下所示：

from django.conf.urls import url
from django.contrib.auth.views import login, logout, password_change, password_change_done

from .views import SignUpView


app_name = 'users'
urlpatterns = [
    url(r'^signup/$', SignUpView.as_view(), name='signup'),
    url(r'^login/$', login, name='login', kwargs={'template_name': 'users/login.html'}),
    url(r'^logout/$', logout, name='logout', kwargs={'next_page': '/'}),
    url(
        r'^password_change/$',
        password_change,
        name='password_change',
        kwargs={
            'template_name': 'users/password_change_form.html',
            'current_app':'users'
        }
    ),
    url(
        r'^password_change/done$',
        password_change_done,
        name='password_change_done',
        kwargs={
            'template_name': 'users/password_change_done.html',
            'current_app':'users'
        }
    ),
]

我也创建users/password_change_form.html，users/password_change_done.html。

但它出现了错误：

需要你的帮助。感谢：）

问题是您在网址配置的顶部指定了app_name。这意味着您定义的所有URL都使用app_name命名空间。因此，密码更改完成网址的最终名称为users:password_change_done，而不是password_change_done。这就是反向查找失败的原因。

您可以通过将post_change_redirect kwarg传递到password_change视图来解决此问题：

from django.core.urlresolvers import reverse

url(
    r'^password_change/$',
    password_change,
    name='password_change',
    kwargs={
        'template_name': 'users/password_change_form.html',
        'current_app':'users',
        'post_change_redirect': reverse_lazy('users:password_change_done')
    }
),

另请注意，自Django 1.9以来current_app参数为deprecated：

不推荐使用current_app参数，将在Django 2.0中删除。来电者应该设置request.current_app。

Django默认password_change不再工作了吗？
