Django错误:未找到页面(404)请求方法: GET请求URL: http://127.0.0.1:8000/helpdesk/login/?next=/

Question

我是个初学者。我正在尝试使用Django帮助台框架构建一个服务台系统。但是，当我单击登录按钮时，会得到以下错误：

页面未找到(404)请求方法: GET请求URL：http://127.0.0.1:8000/helpdesk/login/?next=/使用在moog.urls中定义的URLconf，Django按以下顺序尝试了这些URL模式：

admin/
^dashboard/$ [name='dashboard']
^tickets/$ [name='list']
^tickets/update/$ [name='mass_update']
^tickets/submit/$ [name='submit']
^tickets/(?P<ticket_id>[0-9]+)/$ [name='view']

The current path, helpdesk/login/, didn't match any of these.

请帮助我如何调试和修复此感谢提前。

Answer 1

如日志所示

^login/$ [name='login']
^logout/$ [name='logout']

login网址应该是http://127.0.0.1:8000/login，但是您访问了http://127.0.0.1:8000/helpdesk/login

要么编辑指向/login的前端路径(没有/helpdesk)，要么

# inside urls.py
path(r'helpdesk/', include('helpdesk.urls')),

Answer 2

按以下方式更改设置

LOGIN_REDIRECT_URL = '/login/'
LOGIN_URL = '/login/'

Answer 3

类似于bmons的解决方案，我将以下代码(没有LOGIN_URL = '/login/')添加到项目的settings.py的顶部(或底部)：

# My settings LOGIN_URL = '/login/'

在Django v3.0项目的设置中编写URL时，我们不需要指定“用户”子目录。
