Question

因此，我正在尝试使用基于类的内置视图（PasswordChangeView和PasswordChangeDoneView）实现密码更改功能。现在，当我在内置模板中输入旧密码，新密码并确认密码字段并按Enter（或提交）时，出现“没有反向匹配”错误，提示“未找到'password_change_done'的反向密码。“'password_change_done'不是有效的视图函数或模式名称。”我做了很多研究，发现这是因为我正在使用应用程序名称空间（urls.py中的app_name ='authenticationApp'），这就是django无法找到相反方向的原因。我的简单问题是：如何让内置视图知道其应该在反向函数中使用命名空间的URL？

PS：我知道使用自己的模板将解决此问题。编辑1：

Answer 1

在主urls.py（位于settings.py旁边）中，您应该这样导入视图：

path('password_change/', views.PasswordChangeView.as_view(template_name='your_template.html'), name='password_change'),  # or your path
path('password_change/done/', views.PasswordChangeDoneView.as_view(), name='password_change_done'),

使基于内置类的视图知道Django
