用pycharm开发django项目示例代码

yipeiwu_com5年前Python基础

在pycharm(企业版)中新建Django工程,注意使用虚拟环境

创建成功后,在pycharm显示的工程目录结构如下:

打开pycharm的Terminal,进入该工程的目录新建一个django工程

python3 manage.py startapp django_web

执行成功后,工程目录结构如下:

修改settings.py文件,注册该工程

Django的开发遵循MTV模式(models, templates, views),views.py负责执行操作,models.py负责数据处理(如数据库连接),templates目录下存放网页的模板

首先在templates下新建一个index.html文件,并把以下内容替换到该文件中

<!DOCTYPE html>

<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>The blah</title>
 <link rel="stylesheet" type="text/css" href=" new_blah.css" rel="external nofollow" >
</head>
<body>

<div class="header">
 <img src="images/blah.png">
 <ul class="nav">
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Home</a></li>
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Site</a></li>
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Other</a></li>
 </ul>

</div>

<div class="main-content">
 <h2>Article</h2>
 <ul class="article">

  <li>
   <img src="images/0001.jpg" width="100" height="90">

首先编写views.py文件,定义访问这个index.html文件的操作

def index(request): 

  return render(request, 'index.html')

编写urls.py文件,定义访问这个index.html的url路径(使用正则表达式)

from django.conf.urls import url 
from django.contrib import admin 
from django_web.views import index #导入views.py文件中的index函数 

urlpatterns = [ 
 url(r'^admin/', admin.site.urls), 
 url(r'^index/', index), #在url中凡是以url开头的访问都使用index函数来处理该请求 
]

在pycharm的Terminal中输入命令运行服务器:

python3 manager.py runserver

在浏览器中输入url:http://127.0.0.1:8000/index/ 可以看到如下的格式,接下来要做的就是添加资源

将css文件(css文件的内容在最后)和图片(随意找几张图片,更名为如下所示即可)都复制到env5工程下的一个名为static的文件,工程结构如下:

注意:一定要保证与templates目录同级

修改index.html如下

{% load static %}

<html>

<head>
 <link rel="stylesheet" type="text/css" href="{% static 'css/new_blah.css' %}" rel="external nofollow" >
</head>
<body>

<div class="header">
 <img src="{% static 'images/blah.png' %}">
 <ul class="nav">
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Home</a></li>
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Site</a></li>
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Other</a></li>

在settings.py文件的最后增加如下配置

STATICFILES_DIRS = (os.path.join(BASE_DIR, "static"),)

再次打开浏览器就可以看到正常的显示
