课程大纲:
http://www.cnblogs.com/wupeiqi/articles/4491246.html http://www.cnblogs.com/wupeiqi/articles/4508271.html
一、前端设计
1.实现图片轮播
js下载地址:
http://bxslider.com/
引入
<!-- jQuery library (served from Google) -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<!-- bxSlider Javascript file -->
<script src="/js/jquery.bxslider.min.js"></script>
<!-- bxSlider CSS file -->
<link href="/lib/jquery.bxslider.css" rel="stylesheet" />
加载图片:
<ul class="bxslider">
<li><img src="/images/pic1.jpg" /></li>
<li><img src="/images/pic2.jpg" /></li>
<li><img src="/images/pic3.jpg" /></li>
<li><img src="/images/pic4.jpg" /></li>
</ul>
调用:
$(document).ready(function(){
$(‘.bxslider‘).bxSlider();
});
2.图标资源
Font Awesome
http://fontawesome.io/
a、图片,自己找图片,挖洞
b、现成的图标
css
使用样式
--以前版本
css
图片库
使用样式
-- 现在
css
字体文件
使用样式
c、css
字体文件
样式
=====》 大图片
3.伪类
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>响应式</title>
<style>
@media (min-width: 768px) {
.lead {
background-color: red;
}
}
.c1 {
background-color: green;
}
.clearfix:after {
content: ".";
clear: both;
visibility: hidden;
}
</style>
</head>
<body>
<dev class="lead">
我们都是中国人
</dev>
<div class="c1 clearfix">
<div style="float: right;">
你好
</div>
<div style="float: right;">
china
</div>
<!--<div style="clear: both"></div>-->
</div>
</body>
</html>
二、web框架
1.python web框架分类
#!/usr/bin/env python
#coding:utf-8
import socket
def handle_request(client):
buf = client.recv(1024)
client.send("HTTP/1.1 200 OK\r\n\r\n")
client.send("Hello, Seven")
def main():
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((‘localhost‘,8000))
sock.listen(5)
while True:
connection, address = sock.accept()
handle_request(connection)
connection.close()
if __name__ == ‘__main__‘:
main()
2.MVC web框架
MVC:Models Views Controllers
数据库操作 模板 处理请求的函数
代码块的归类结构
MTV:Models Templates Views
数据库操作 模板 处理请求的函数
3.Django基础
Django框架属于MTV框架。程序需要的操作的:
1.models
2.Templates
3.Views
4.urls
三、Django
1.安装
pip install django 1.9.5
2.创建Django程序框架
使用命令创建
django-admin startproject demo 创建projects
cd demo
python manage.py startapp app0 创建应用
使用pycharm进行创建项目和应用
3.执行程序
进入项目, python manage.py runserver 127.0.0.1:8000
4.创建数据表
python manage.py makemigrations #生成配置文件
python manage.py migrate #根据配置文件创建数据库相关 表
5.django默认后台管理
创建超级用户名 python manage.py createsuperuser
6.路由系统
静态路由
动态路由
安照顺序,第n个匹配的数据交给函数的第n个参数,严格按照顺序
url(r‘^page/(\d+)/(\d+)‘,views.page)
模板的方法,将匹配的参数,传给指定的形式参数
url(r‘^page/(?P<n1>\d+)/(?P<n2>\d+)‘,views.page)
二级路由
app01
urls.py
project name
URL:app01 ->include("app01.urls")
7.基本数据库操作
ORM框架
code first
自己写类 -->数据库表
db first
自己写命令操作数据库-->更新类
使用类进行数据操作
创建类
from django.db import models
class UserInfo(models.Model):
username = models.CharField(max_length=32)
password = models.CharField(max_length=32)
age = models.IntegerField()
配置
setting
INSTALLED_APPS = [
‘django.contrib.admin‘,
‘django.contrib.auth‘,
‘django.contrib.contenttypes‘,
‘django.contrib.sessions‘,
‘django.contrib.messages‘,
‘django.contrib.staticfiles‘,
‘app01‘,
]
使用命令根据类创建表
python manage.py makemigrations #生成配置文件
python manage.py migrate #根据配置文件创建数据库相关 表
默认表名:
appname_classname
d.
views中导入models
e.
POST提交数据
settings里操作:
MIDDLEWARE_CLASSES = [
‘django.middleware.security.SecurityMiddleware‘,
‘django.contrib.sessions.middleware.SessionMiddleware‘,
‘django.middleware.common.CommonMiddleware‘,
# ‘django.middleware.csrf.CsrfViewMiddleware‘,
‘django.contrib.auth.middleware.AuthenticationMiddleware‘,
‘django.contrib.auth.middleware.SessionAuthenticationMiddleware‘,
‘django.contrib.messages.middleware.MessageMiddleware‘,
‘django.middleware.clickjacking.XFrameOptionsMiddleware‘,
]
