目录
一、创建django项目
二、修改默认配置
三、配置数据库连接
四、创建表结构
五、在app当中创建静态文件
六、页面实战-部门管理
1、实现一个部门列表页面
2、实现新增部门页面
3、实现删除部门
4、实现部门编辑功能
七、模版的继承
1、创建模板layout.html
1）将公共的部分写进模版
2）后续新的html页面使用下面方法继承模版
2、将depart_list.html页面使用模版重构
3、将depart_add.html页面重构
4、将depart_edit.html页面重构
八、页面实战-用户管理
1、uri注册
2、views.py
3、用户列表页面
4、添加用户user_add.html--- 老方法
5、添加用户user_model_form_add.html--- 新方法（ModelForm）
6、解决提示英文问题
7、编辑用户 -新增user_edit.html页面
8、编辑用户 -修改views.py
9、修改数据库入职时间为年月日格式
10、删除用户在views.py新增user_delete方法
一、创建django项目
使用pycharm创建django项目
二、修改默认配置
1、删除settings配置
删除下图[]内容
2、删除templates文件夹
三、创建app（应用）与注册应用
1、创建app
# XXX项目名
python manage.py startapp xxx2、注册app
修改settings如下图，红色方框是创建的app名
三、配置数据库连接
1、安装pymysql
pip install pymysql
2、配置在项目同名包下的_init_.py里面添加
import pymysql
pymysql.install_as_MySQLdb()3、修改settings.py
,注释db.sqlite3的配置新增下图
# DATABASES = {
# 'default': {
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': BASE_DIR / 'db.sqlite3',
# }
# }
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # 数据库的类型
'NAME': 'texx', # 所使用的的数据库的名字
'USER': 'root', # 数据库服务器的用户
'PASSWORD': 'xxxx', # 密码
'HOST': '127.0.0.1', # 主机
'PORT': '3306', # 端口
}
}四、创建表结构
1、在models.py创建类
from django.db import models
# Create your models here.
class Department(models.Model):
"""部门表"""
name = models.CharField(verbose_name='部门名称', max_length=20)
class UserInfo(models.Model):
"""员工表"""
name = models.CharField(verbose_name='姓名', max_length=20)
password = models.CharField(verbose_name='密码', max_length=64)
age = models.IntegerField(verbose_name='年龄')
gender_choices = ((1, '男'), (2, '女'))
gender = models.SmallIntegerField(verbose_name='性别',choices=gender_choices)
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')
# depart会自动生成字段为depart_id
# 级联删除 on_delete=models.CASCADE
# 置空 on_delete=models.SET_NULL 但是必须和null=True, blank=True配合使用，因为你得支持为null
depart = models.ForeignKey(to='Department', to_field='id', on_delete=models.CASCADE)
2、创建一个mysql数据库（略）
3、django命令生成库表
python manage.py makemigrations
python manage.py migrate另一个方法：按下图操作之后就可省略上图 python manage.py 命令直接输入后面的即可
五、在app当中创建静态文件
1、创建下图目录
2、将下载的bootstrap-3.4.1复制到plugins
3、将下载的jquery-3.6.3.min.js复制到js
4、在app应用下创建templates文件夹
六、页面实战-部门管理
1、实现一个部门列表页面
1）设置部门列表路由
from django.contrib import admin
from django.urls import path
from TestManagementSystem import views
urlpatterns = [
# path('admin/', admin.site.urls),
path('depart/list/', views.depart_list),
]
2）创建部门列表views.py视图
from django.shortcuts import render
from TestManagementSystem import models
# Create your views here.
def depart_list(request):
"""部门列表"""
# 查询所有部门
depart_set = models.Department.objects.all()
print(depart_set)
return render(request, 'depart_list.html', {"depart_set": depart_set})
3）创建部门列表html页面
在templates下创建depart_list.html
先引入样式、js等

#模版块
{% block content %}{% endblock %}1、创建模板layout.html
1）将公共的部分写进模版

1、uri注册
因为和部门管理类似

# 部门管理
path('depart/list/', views.depart_list),

path('depart/<int:nid>/edit/', views.depart_edit),
# 用户管理
path('user/list/', views.user_list),
path('user/add/', views.user_add),
path('user/model/form/add/', views.user_model_form_add), # 新方法实现
path('user/<int:nid>/edit/', views.user_edit),
path('user/<int:nid>/delete/', views.user_delete) # 与部门删除方式不一样
