如何解决NoReverseMatch

Question

我有项目的urls.py文件，它位于其中的forecast/urls，我正在尝试为我的应用程序的URL设置URL路由

from django.contrib import admin                             
from django.urls import path,include                       
from django.contrib.auth import login                         
       urlpatterns = [
            path('auth/',include
                     ('authorization.urls')),
            ]

在authorization/urls.py中

from django.urls import path                               
from . import views                                        
        urlpatterns = [
             path('login/',
             views.login_name), 
         ]

运行服务器后，我想打开http://127.0.0.1:8000/auth/login/，我得到了

NoReverseMatch at/   
auth/login/
 Reverse for 'login' not found. 'login' is 
 not a valid view function or pattern    
 name.

根据我的url设置，我希望项目urls.py的路径功能将提供给包含的授权/urls.py路径auth/，而不是authorization/urls.py的第二条路径将比构造的login添加到模式auth/login/如果我是对的，将给出我的视图函数，为什么会出现NoReverse错误。谁能指导我我做错了

您需要给URL起一个名字，以便在您想要反转它时可以使用它

path('login/', views.login_name, name='login'),
