用pycharm开发django项目示例代码
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"> <h3><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" >The blah</a></h3> <p>This is a dangerously delicious cake.</p> </li> <li> <img src="images/0002.jpg" width="100" height="90"> <h3><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" >The blah</a></h3> <p>It's always taco night somewhere!</p> </li> <li> <img src="images/0003.jpg" width="100" height="90"> <h3><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" >The blah</a></h3> <p>Omelette you in on a little secret </p> </li> <li> <img src="images/0004.jpg" width="100" height="90"> <h3><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" >The blah</a></h3> <p>It's a sandwich. That's all we .</p> </li> </ul> </div> <div class="footer"> <p>© Mugglecoding</p> </div> </body> </html> <--!http://css3gen.com/box-shadow/-->
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> </ul> </div> <div class="main-content"> <h2>Article</h2> <ul class="articles"> <li> <img src="{% static 'images/0001.jpg' %}" width="100" height="91"> <div class="article-info"> <h3><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" >The blah</a></h3> <p class="meta-info"> <span class="meta-cate">fun</span> <span class="meta-cate">Wow</span> </p> <p class="description">Just say something.</p> </div> <div class="rate"> <span class="rate-score">4.5</span> </div> </li> <li> <img src="{% static 'images/0002.jpg' %}" width="100" height="91"> <div class="article-info"> <h3><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" >The blah</a></h3> <p class="meta-info"> <span class="meta-cate">butt</span> <span class="meta-cate">NSFW</span> </p> <p class="description">Just say something.</p> </div> <div class="rate"> <img src="{% static 'images/Fire.png' %}" width="18" height="18"> <span class="rate-score">5.0</span> </div> </li> <li> <img src="{% static 'images/0003.jpg' %}" width="100" height="91"> <div class="article-info"> <h3><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" >The blah</a></h3> <p class="meta-info"> <span class="meta-cate">sea</span> </p> <p class="description">Just say something.</p> </div> <div class="rate"> <span class="rate-score">3.5</span> </div> </li> <li> <img src="{% static 'images/0004.jpg' %}" width="100" height="91"> <div class="article-info"> <h3><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" >The blah</a></h3> <p class="meta-info"> <span class="meta-cate">bay</span> <span class="meta-cate">boat</span> <span class="meta-cate">beach</span> </p> <p class="description">Just say something.</p> </div> <div class="rate"> <span class="rate-score">3.0</span> </div> </li> </ul> </div> <div class="footer"> <p>© Mugglecoding</p> </div> </body> </html>
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
css文件
