对DJango视图(views)和模版(templates)的使用详解

# views.py
# 一个简单的视图,固定返回 hrllo world
def index(request):
  return HttpResponse('hello world')

# fanlie/fanlei/urls.py
from django.conf.urls import include, url
from django.contrib import admin
from booktest import views

urlpatterns = [
  url(r'^admin/', include(admin.site.urls)),
  # 如果匹配的是空就就调用views.index返回首页
  url(r'^$',views.index),
]

# fanlie/fanlei/urls.py
urlpatterns = [
  url(r'^admin/', include(admin.site.urls)),
  # 什么都不干直接去booktest.urls去找相应的匹配
  url(r'^',include('booktest.urls')),
]

# fanlei/booktest/urls.py
from django.conf.urls import url
from . import views

urlpatterns = [
  # js结尾就是调用视图中的函数 js
  url(r'.*.js',views.js),
  # 直接访问代表是首页,调用视图中的函数index
  url(r'^$', views.index),
  # 如果是image开头的代表是图片,直接让DJango去打开对应的图片返回
  url(r'^images/(?P<path>.*)', 'django.views.static.serve', {'document_root':'/home/python/Desktop/fanlei/templates/booktest/images'}),

]

from django.shortcuts import render

def index(request):
  # 返回引号中的文件的内容
  return render(request, 'booktest/index.html')

def js(request):
  # 返回引号中的文件的内容
  return render(request,'booktest/jquery-1.12.4.js')
