我试图在我的项目（password_forgot）中安装brutasse/django-password-reset（来自github）作为应用程序。不幸的是，每当我在忘记密码页面（login/e-mail）上传递正确的.../password_forgot/recover/时，我都会收到以下错误：
异常类型：NoReverseMatch异常值：反向 带参数的'password_reset_sent' '（' ImlkZWFsbmEuc3VraWVua2FAb25ldC5wbCI：1b5BRG：UUCzmKT_IB4UjnLs59AzXDuDuoI '）' 和找不到关键字参数“{}”。尝试了0种模式：[]
这是追溯：

我是django和stackoverflow的新手，请告诉我是否需要发布更多信息。
答案 0 :(得分：0)
您的问题是成功网址没有命名空间
success_url_name = 'password_reset_sent'
但您在网址中使用了命名空间。
url(r'^password_forgot/', include('password_forgot.urls', namespace='password_forgot')),
您应该从网址中删除命名空间，
success_url_name = 'password_reset_sent'
url(r'^password_forgot/', include('password_forgot.urls')),
或者您可以尝试将名称空间添加到视图中：
success_url_name = 'password_forgot:password_reset_sent'
url(r'^password_forgot/', include('password_forgot.urls', namespace='password_forgot')),
