启动项目命令
python manage.py runserver动态获取当前时间
javascript实现数据动态更新代码
<script>setInterval(function() {var currentTimeElement = document.getElementById('current-time');var currentTime = new Date();currentTimeElement.textContent = 'Current time: ' +currentTime.getFullYear() + '-' +(currentTime.getMonth() + 1) + '-' +currentTime.getDate() + ' ' + currentTime.getHours() + ':'+ currentTime.getMinutes() + ':' + currentTime.getSeconds();}, 1000); // Update every second</script>实现数据添加功能
实现数据删除功能
创建django项目命令，在需要生成项目的文件夹中打开终端运行
django-admin startproject mysite数据库启动
mysql -u root -p生成app命令
python manage.py startapp app01注册app
orm建成数据库表（外键），性别约束
自己创建数据库
启动mysql服务
mysql -u root -p自带工具创建数据库
create database t_day1 DEFAULT CHARSET utf8 COLLATE utf8_general_ci
修改setting.py文件里面数据库的内容
DATABASES = {'default': {'ENGINE': 'django.db.backends.mysql','NAME':'dbname','USER': 'root','PASSWORD': 'xxx','HOST': '','PORT': '',}
}django命令生成数据库表
python manage.py makemigrationspython manage.py migrate 
查看数据库表
表结构创建成功
静态文件和模板文件（jQuery以及bootstrap有需要的可以私信）
部门管理
先体验
后续：Django中提供Form和ModelForm组件（方便)
使用bootstrap表格样式
