员工管理系统
1.新建项目
2.创建app
python manage.py startapp app01
2.1 注册app
3. 设计表结构(django)
from django.db import modelsclass Department(models.Model):""" 部门表 """title = models.CharField(verbose_name='标题', max_length=32)class UserInfo(models.Model):""" 员工表 """name = models.CharField(verbose_name="姓名", max_length=16)password = models.CharField(verbose_name="密码", max_length=64)age = models.IntegerField(verbose_name="年龄")account = models.DecimalField(verbose_name="账户余额", max_digits=10, decimal_places=2, default=0)create_time = models.DateTimeField(verbose_name="入职时间")# 无约束# depart_id = models.BigIntegerField(verbose_name="部门ID")# 1.有约束# - to,与那张表关联# - to_field,表中的那一列关联# 2.django自动# - 写的depart# - 生成数据列 depart_id# 3.部门表被删除# ### 3.1 级联删除depart = models.ForeignKey(to="Department", to_field="id", on_delete=models.CASCADE)# ### 3.2 置空# depart = models.ForeignKey(to="Department", to_field="id", null=True, blank=True, on_delete=models.SET_NULL)# 在django中做的约束gender_choices = ((1, "男"),(2, "女"),)gender = models.SmallIntegerField(verbose_name="性别", choices=gender_choices)
4. 在MySQL中生成表
create database gx_day16 DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
- django命令生成数据库表
python manage.py makemigrations
python manage.py migrate
5. 静态文件管理
static目录
6. 部门管理
体验,最原始方法来做。Django中提供Form和ModelForm组件(方便)
7.模板的继承
- 部门列表
- 添加部门
- 编辑部门
定义目版:layout.html
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><link rel="stylesheet" href="{% static 'plugin...min.css' %}">{% block css %}{% endblock %}
</head>
<body><h1>标题</h1><div>{% block content %}{% endblock %}</div><h1>底部</h1><script src="{% static 'js/jquery-3.6.0.min.js' %}"></script>{% block js %}{% endblock %}
</body>
</html>
继承母版:
{% extends 'layout.html' %}{% block css %}<link rel="stylesheet" href="{% static 'pluxxx.css' %}"><style>...</style>
{% endblock %}{% block content %}<h1>首页</h1>
{% endblock %}{% block js %}<script src="{% static 'js/jqxxxin.js' %}"></script>
{% endblock %}
8.用户管理
insert into app01_userinfo(name,password,age,account,create_time,gender,depart_id) values("韩超","666",23,100.68,"2020-01-11",2,1);insert into app01_userinfo(name,password,age,account,create_time,gender,depart_id) values("刘东","123",23,100.68,"2010-11-11",1,4);insert into app01_userinfo(name,password,age,account,create_time,gender,depart_id) values("朱虎飞","999",33,9900.68,"2021-05-11",1,1);
