一、Django ModelForm

• 本章使用 ModelForm 主要实现一下两种功能：
  • 自动生成表单 HTML
  • 实现表单验证功能

1.2、创建用于实现注册的Model

(Bug_manager) daizhe@daizhedeMacBook-Pro Bug_manager % cat users_app/models.py 
from django.db import models
# Create your models here.

class UserInfo(models.Model):
    """
    CharField : 字符串类型字段
    verbose_name : 字段注释
    max_length : 字段长度
    Django ORM 中也提供了一个 EmailField 但是本质上 还是 CharField
    """
    username = models.CharField(verbose_name='用户名', max_length=32)
    email = models.EmailField(verbose_name='邮箱', max_length=32)
    models_phone = models.CharField(verbose_name='手机号', max_length=32)
    password = models.CharField(verbose_name='密码', max_length=32)

• 生成数据库迁移脚本

(Bug_manager) daizhe@daizhedeMacBook-Pro Bug_manager % python3 manage.py makemigrations
Migrations for 'users_app':
  users_app/migrations/0001_initial.py
    - Create model UserInfo

• 迁移数据

(Bug_manager) daizhe@daizhedeMacBook-Pro Bug_manager % python3 manage.py migrate
