终端:
cd django
cd day03
cd mysite3
python3 manage.py startapp music(应用名)
在settings.py的INSTALLED_APPS中添加应用名即可
news开头的交由news管理
music开头的交由music管理
语法:include(‘app名字.url模块名’)
作用:用于将当前路由转到各个应用的路由配置文件的urlpatterns进行分布式处理
http://127.0.0.1:8000/music/index
在urls.py中添加:
path('music/',include('music.urls'))
import某个已有的库,可以将鼠标放在红波浪线处 Alt+回车 直接导入
app-new-pythonfile-urls
#http://127.0.0.1:8000/music/index
应用music的urls.py
from django.urls import path
from . import views
urlpatterns = [
path('index',views.index_view)
]
终端:在django/day03/mysite3下
python3 manage.py startapp news
python3 manage.py startapp sport
添加内容:
#http://127.0.0.1:8000/news/index
path('news/',include('news.urls')),
#http://127.0.0.1:8000/sport/index
path('sport/',include('sport.urls'))
from django.urls import path
from . import views
urlpatterns = [
#http://127.0.0.1:8000/news/index
path('index',views.index_view)
]
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def index_view(request):
return HttpResponse('这是新闻频道首页')
应用同名嵌套文件夹——避免找不到应用下的模版
news-右键-new-directory-templates-右键-new-directory-news-右键-new-html-index
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>新闻频道</title>
</head>
<body>
我是新闻频道首页
</body>
</html>
news的views.py:
from django.http import HttpResponse
from django.shortcuts import render
# Create your views here.
def index_view(request):
return render(request,'news/index.html')
为了分而治之,引入了应用、分布式路由和应用下的模版。
