创建数据库
创建用户相关app，名称叫app_users
开始编写用户相关名称叫app_users的app数据库操作models.py文件
#!/usr/bin/env python
# -*- coding:utf-8 -*- from __future__ import unicode_literals
from django.db import models # 导入models对象 class app_users(models.Model): # 创建类必须继承models.Model，类名将是在数据库里的表名称
password = models.CharField(max_length=128, verbose_name='密码', default='', blank=False) # 密码字段，长度128，默认值为空字符，前端不允许用户输入空
last_login = models.DateTimeField(verbose_name='登录日期', null=True) # 允许为空
is_superuser = models.BooleanField(max_length=1, verbose_name='用户身份', name=False)
username = models.CharField(max_length=150, verbose_name='用户名', null=False, blank=False)
first_name = models.CharField(max_length=30, verbose_name='拓展1', null=False)
last_name = models.CharField(max_length=30, verbose_name='拓展2', null=False)
email = models.EmailField(max_length=254, verbose_name='邮箱', null=False, blank=False)
is_staff = models.BooleanField(max_length=1, verbose_name='是否是员工', null=False)
is_active = models.BooleanField(max_length=1, verbose_name='是否激活', null=False)
date_joined = models.DateTimeField(verbose_name='注册日期', null=True)
nick_name = models.CharField(max_length=50, verbose_name='昵称', default='')
birday = models.DateField(verbose_name='生日', null=True)
gender = models.CharField(max_length=3, verbose_name='性别', choices=(("male", "男"), ("female", "女")), default='male')
address = models.CharField(max_length=100, verbose_name='地区', default='')
mobile = models.CharField(max_length=11, verbose_name='手机', null=True, blank=True)
image = models.ImageField(upload_to='image/%Y/%m', verbose_name='头像', default='image/default.png', max_length=100) class Meta:
verbose_name = '用户信息表'
verbose_name_plural = verbose_name
将名称叫app_users的app注册
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'app_users', # 注册 APP
]
执行命令生成数据库表
我们继续完成名称叫app_users的app数据库操作models.py文件，我们在这个models.py文件操作3张表
#!/usr/bin/env python
# -*- coding:utf-8 -*-
from __future__ import unicode_literals
from datetime import datetime from django.db import models # 导入models对象 class Users(models.Model): # 创建类必须继承models.Model，类名将是在数据库里的表名称

last_login = models.DateTimeField(verbose_name='登录日期', null=True) # 允许为空
is_superuser = models.BooleanField(max_length=1, verbose_name='用户身份', name=False)
username = models.CharField(max_length=150, verbose_name='用户名', null=False, blank=False)
first_name = models.CharField(max_length=30, verbose_name='拓展1', null=False)

verbose_name_plural = verbose_name class Banner(models.Model):
