Django中的文件表示的含义

创建新的app名称：在Terminal中运行 python manage.py startapp app02

admin.py 操作数据库的

wapps.py 当前app的配置文件
models.py 映射类的存放位置与数据库对应
tests.py 做单元测试的
views.py 写函数或者类的后台

admin.py Django自带的后台管理相关配置
apps.py
models.py 写类，根据类创建相关数据库表
tests.py 做单元测试的
views.py 业务处理，这个views不一定是一个py文件，可以是一个文件夹

路由分发：在项目名称->urls->urlpatterns下

path('app01/',include('app01.urls')),
    path('app02/',include('app02.urls')),
    
    urlpatterns = [
    # path('admin/', admin.site.urls),
    # path('index/',views.index),

    # 包含其他App中的path
    path('app01/',include('app01.urls')),
    path('app02/',include('app02.urls')),
    # path('项目名/',include('项目名.项目名下面存放url的文件'))

    # 出错存在的网页
    # path('^',default)
    url(r'^',default),
    # path('index/',views.index,name)

    # 根据名字反生成url
    # url(r'^index/(w+)/',views.index,name='n1')
]
    
    
    
    
    """untitled1 URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/3.2/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'))
"""

路由系统

 a、/login/ --> def login                                  静态路由
    http://127.0.0.1:8000/edit/?nid=fff
    path('edit/',views.edit),
    def edit(request):
        request.GET.get('nid')
        return HttpResponse('ooo')
b、/add-user/(d+)正则表达式 --> def add_user(request)   动态路由
http://127.0.0.1:8000/edit/fff
path('edit/(w+)/',views.edit),
def edit(request,a1)
(w+)对应a1

path('edit/(w+)/.html',views.edit),使其有后缀名

按位置放
path('edit/(w+)/(w+)/.html',views.edit)
def edit(request,a1,a2)
前一个 (w+)对应a1,后一个 (w+)对应a2
这种可以与def edit(request,*arges,**kwarges)

按名称放
path('edit/(?Pw+)/(?Pw+)/.html',views.edit)

终止符
path('edit$',views.edit),

伪静态
path('edit/(w+).html$',view.edit)

# 出错存在的网页
# path('^',default)
url(r'^',default)
