users modesl.py设计
| UserProfile | 用户信息 |
| EmailVerifyRecord | 验证码 |
| Banner | 轮播图 |
之前我们生成了Django默认的数据表，里面有张表示auth-user
mysql> desc auth_user; +--------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | password | varchar(128) | NO | | NULL | | | last_login | datetime(6) | YES | | NULL | | | is_superuser | tinyint(1) | NO | | NULL | | | username | varchar(30) | NO | UNI | NULL | | | first_name | varchar(30) | NO | | NULL | | | last_name | varchar(30) | NO | | NULL | | | email | varchar(254) | NO | | NULL | | | is_staff | tinyint(1) | NO | | NULL | | | is_active | tinyint(1) | NO | | NULL | | | date_joined | datetime(6) | NO | | NULL | | +--------------+--------------+------+-----+---------+----------------+
根据项目的需求，这些字段无法满足，因此我们还需要添加一些字段；编辑apps.users.models.py 新建一张表继承auth-user表
from django.db import models
from django.contrib.auth.models import AbstractUser #导入auth-user表模块
class UserProfile(AbstractUser):
nick_name = models.CharField(max_length=50, verbose_name='昵称', default='')
birthday = models.DateField(verbose_name='生日', null=True, blank=True)
gender = models.CharField(max_length=6, choices=(('male', '男'),('female', '女')), default='female')
address = models.CharField(max_length=100, default='')
mobile = models.CharField(max_length=11, null=True, blank=True)
image = models.ImageField(upload_to='image/%Y/%m', default='image/default.png', max_length=100)
class Meta:
verbose_name = '用户信息'
verbose_name_plural = verbose_name
def __str__(self):
return self.username
因为上面我们使用到了imageField字段类型，但是imageField字段依赖于Pillow
(mxonline) C:Usersuser>pip install pillow
修改settings.py，设置用户认证模型为我们新建的UserProfile
AUTH_USER_MODEL = 'users.UserProfile' #MIDDLEWARE_CLASSES行上面添加此行
同步数据表到数据库
manage.py@mxonline > makemigrations users manage.py@mxonline > migrate users #中途需要确认，输入yes
进入数据库查看表users_userprofile
mysql> desc users_userprofile ; +--------------+--------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +--------------+--------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | password | varchar(128) | NO | | NULL | | | last_login | datetime(6) | YES | | NULL | | | is_superuser | tinyint(1) | NO | | NULL | | | username | varchar(30) | NO | UNI | NULL | | | first_name | varchar(30) | NO | | NULL | | | last_name | varchar(30) | NO | | NULL | | | email | varchar(254) | NO | | NULL | | | is_staff | tinyint(1) | NO | | NULL | | | is_active | tinyint(1) | NO | | NULL | | | date_joined | datetime(6) | NO | | NULL | | | nick_name | varchar(50) | NO | | NULL | | | birthday | date | YES | | NULL | | | gender | varchar(6) | NO | | NULL | | | address | varchar(100) | NO | | NULL | | | mobile | varchar(11) | YES | | NULL | | | image | varchar(100) | NO | | NULL | | +--------------+--------------+------+-----+---------+----------------+
apps.users.models.py再加上两张表
from django.db import models
from django.contrib.auth.models import AbstractUser # 导入auth-user表模块
from datetime import datetime
class UserProfile(AbstractUser):
nick_name = models.CharField(max_length=50, verbose_name='昵称', default='')

address = models.CharField(max_length=100, default='')
mobile = models.CharField(max_length=11, null=True, blank=True)
image = models.ImageField(upload_to='image/%Y/%m', default='image/default.png', max_length=100)
class Meta:
verbose_name = '用户信息'
verbose_name_plural = verbose_name
def __str__(self):
return self.username
class EmailVerifyRecord(models.Model):
code = models.CharField(max_length=20, verbose_name='验证码')
email = models.EmailField(max_length=50, verbose_name='邮箱')
send_type = models.CharField(choices=(('register', '注册'), ('forget', '找回密码'),('hmail', '修改邮箱')), max_length=10, verbose_name='发送类型')
send_time = models.DateField(default=datetime.now, verbose_name='发送时间')
class Meta:
verbose_name = '邮箱验证码'
verbose_name_plural = verbose_name
def __str__(self):
return '{0}({1})'.format(self.code, self.email)
class Banner(models.Model):
title = models.CharField(max_length=100, verbose_name='标题')
image = models.ImageField(upload_to='banner/%Y/%m', verbose_name='轮播图', max_length=100)
url = models.URLField(max_length=200, verbose_name='访问地址')
index = models.IntegerField(default=100, verbose_name='顺序')
add_time = models.DateField(default=datetime.now, verbose_name='添加时间')
class Meta:
verbose_name = '轮播图'
verbose_name_plural = verbose_name
def __str__(self):
return self.title
最后执行，同步命令同步到数据库
