前提：在 luffy 虚拟环境下

1.终端从项目根目录进入apps目录
>: cd luffyapi & cd apps

2.创建app
>: python ../../manage.py startapp user
# 创建应用是基于manage.py执行命令,所以要找到manage.py

from django.db import models
from django.contrib.auth.models import AbstractUser
class User(AbstractUser):
    mobile = models.CharField(max_length=11, unique=True)
    icon = models.ImageField(upload_to=‘icon‘, default=‘icon/default.png‘)

    class Meta:
        db_table = ‘luffy_user‘
        verbose_name = ‘用户表‘
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.username

INSTALLED_APPS = [
    # ...
    ‘user‘,
]

# 自定义User表  因为User表是基于 auth_user 表创建
AUTH_USER_MODEL = ‘user.User‘

MEDIA_URL = ‘/media/‘
MEDIA_ROOT = os.path.join(BASE_DIR, ‘media‘)

"""
├── luffyapi
    └── luffyapi/
        └── media/      
            └── icon 
                └── default.png

# 数据迁移是基于manage.py执行命令,所以要找到manage.py
迁移命令: 
python manage.py makemigrations 
python manage.py migrate

安装Pillow模块
>: pip install Pillow
