python在windows中启动方法两种：

1.通过windows中使用控制台

2.通过pycharm启动

一、在windows中启动：

1.Win+R  --> CMD

2.下载django包

pip3 install django

3.创建一个项目叫mysite

django-admin startproject mysite

4.创建一个应用叫blog

django-admin manage.py startapp blog

5.可以查看一下mysite的目录

//blog也是一个文件，查看blog 目录

cd blog

admin.py

tests.py

views.py 盛放实现具体功能的函数的

models.py 操作数据库的，放与操作数据库相关的内容

admin.py 强大的后台管理系统，通过web页面管理后台

settings.py 全局的与django相关的所有的配置信息

进入mysite/mysite目录：

setting.py

INSTALLED_APP = {

存放所有的应用名称，比如blog

"blog",

}

urls.py

urlpatterns = [ #把路径分发到不同的路径函数里去

path('admin/', admin.site.urls), #自带的，提供一个管理数据库的页面，model是创建数据库

path('login',login/) #前面login是路径，后面是函数

]

__init__.py

二、在pycharm中创建一个基本功能，显示页面的

1.打开pycharm

2.File --> New  Project--> Django--> 路径后面名字就叫django_lesson --> Create

4.左边的目录

k

5.目录展开

6.编辑： urls.py

from django.contrib import admin

from django.urls import path

#from django.conf.urls import url

from blog import views

urlpatterns = [

path('admin/', admin.site.urls),

path('show_time/',views.show_time),

]

备注：  第一个show_time/前面不能跟^ 符号，否则找不到此路径

7.编辑  blog-->migrations-->views

from django.shortcuts import render,HttpResponse

import time

# Create your views here.

#浏览器发起请求后，客户端的请求信息全部打包在req里面,return一个http response对象

def show_time(req):

#return HttpResponse("hello")

t=time.ctime()

#return render(req,"index.html",locals())

return render(req,"index.html",{"time":t}) #render做渲染，只要是返回的，都是返回的HttpResponse对象

在右侧的templates中创建一个名为index.html的页面

编辑index.html

Title

hello yuan

hello {{ time }}

8.在pycharm的右下角的Terminal中启动该项目

python  manage.py   runserver  8889

9.在浏览器访问8889端口的show_time路径，输入  http://127.0.0.1:8889/show_time

三、在django中引入js文件,js文件要放在static目录中，这个目录跟app目录平行，同一级
