1.视频【2-1~2-12】

2.笔记

1.创建

1.1创建项目

 

 

 

 

 

 

1.2 创建app

python manage.py startapp app01

 

 

 

 

注册app：

 

 

 

 

2.3 设计表结构

 

 

 

 

 

 

from django.db import models


class 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)

 

2.4 工具连接mysql

create database gx_day16 DEFAULT CHARSET utf8 COLLATE utf8_general_ci;

修改配置文件，连接MySQL

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'gx_day16',  # 数据库名字
        'USER': 'root',
        'PASSWORD': 'root123',
        'HOST': '127.0.0.1',  # 那台机器安装了MySQL
        'PORT': 3306,
    }
}

 

 

django命令生成数据库表

python manage.py makemigrations
python manage.py migrate

 

 

 

表结构创建成功：

 

 

2.5 静态文件管理

 

 

2.6  部门管理

体验，最原始方法来做。

Django中提供Form和ModelForm组件（方便）

 

代码：

url.py

from django.urls import path
from app01 import views

urlpatterns = [
    # path('admin/', admin.site.urls),
    path('depart/list/', views.depart_list),
    path('depart/add/', views.depart_add),
    path('depart/del/', views.depart_del),
    path('depart/<int:id>/edit/', views.depart_edit), #edit
]

 

 

views.py

from django.shortcuts import render,redirect
from app01 import models


def depart_list(request):
　　# 部门列表
    departs = models.Department.objects.all()
    return render(request, 'depart_list.html', {'depart_list': departs})


def depart_add(request):
　　# 添加部门
    if request.method == 'GET':
        return render(request, 'depart_add.html')

    title = request.POST.get('title')
    models.Department.objects.create(title=title)
    return redirect('/depart/list/')


def depart_del(request):
　　# 删除部门
    depart_id = request.GET.get('id')
    models.Department.objects.filter(id=depart_id).delete()
    return redirect('/depart/list/')


def depart_edit(request, id):
　　# 修改部门
    if request.method == "GET":
        row_object = models.Department.objects.filter(id=id).first()
        return render(request, 'depart_edit.html', {'row_object': row_object})
    title = request.POST.get('title')
    models.Department.objects.filter(id=id).update(title=title)
    return redirect('/depart/list/')

 2.7 模板的继承

  • 部门列表

  • 添加部门

  • 编辑部门
