"""guest URL Configuration
The `urlpatterns` list routes URLs to views. For more information please see:
https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: path('', views.home, name='home')
Class-based views
1. Add an import: from other_app.views import Home
2. Add a URL to urlpatterns: path('', Home.as_view(), name='home')
Including another URLconf
1. Import the include() function: from django.urls import include, path
2. Add a URL to urlpatterns: path('blog/', include('blog.urls'))

path() 函数是 Django 2.0 版本引入的新函数,它更加直观和易用,支持使用 str 类型的路由,可以通过 , 等转换器来定义动态参数,而且不再需要使用正则表达式来匹配 URL,大大简化了 URL 配置的过程。
url() 函数是 Django 1.x 版本中用于 URL 配置的函数,它的语法和 path() 不同,需要使用正则表达式来匹配 URL。
输入 admin admin123456
add 添加用户
user1 user123456
退出,用user1 进入
登录失败 ;
修改成密码为user12345678 登录成功 :

清理缓存
直接访问
http://127.0.0.1:8000/event_manage/
在访问被@login_reuqired 装饰的视图时,默认跳转的URL 中包含"acount/login/"。
修改.../urls.py 增加新的路径位置:
path('',views.index),
path('accounts/login/',views.index)
跳转到 登录
python
#from django.urls import url
from django.contrib import admin
from django.urls import path
from sign import views
urlpatterns = [
path('',views.index),
path('admin/', admin.site.urls),
path('index/', views.index), # 添加 index 、路径配置
path('login_action/',views.login_action), # 处理登录请求
path('event_manage/',views.event_manage) , # 处理登录请求
path('accounts/login/',views.index)
