Django实现学生管理系统

框架(架构)  /  管理员 发布于 7年前   151

Django学习笔记-学生管理系统（Django实现）笔记中仅实现了对数据的全部查询。

下面实现新增、删除、修改，代码如下。

下面的代码没有对输入框内容进行限制，如果输入不符合规则的内容，会出现错误。

本篇更新完毕后Django更新暂停一段，由于工作岗位是测试工程师，后面将重点关注测试相关内容。

views.py

静态资源文件：

nav.css

*{  margin: 0;  padding: 0;} .nav{  list-style-type: none;  margin: 0;  padding: 0;  overflow: hidden;  background-color: #333;  position: fixed;  top: 0;  width: 100%;} .nav li{  float: left;} .nav li a {  display: block;  color: white;  text-align: center;  padding: 14px 16px;  text-decoration: none;} .nav li a:hover:not(.active) {  background-color: #111;} .active {  background-color: #4CAF50;}

table.css

.table{  margin-top:50px;width:100% ;border:solid #add9c0; border-width:1px 0px 0px 1px;} .table tr td {  border:solid #add9c0; border-width:0px 1px 1px 0px; padding:10px 0px;font-size:18px;align:center;} .table tr td input{  width: 250px; height: 30px;font-size:18px}

实现效果如下：
