创建user应用与User表

06.创建user应用与User表

一、创建应用user

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

二. 创建User表对应的model：user/models.py

from django.db import models
from django.contrib.auth.models import AbstractUser
class User(AbstractUser):
    mobile = models.CharField(max_length=11, unique=True)
    # 需要pillow包的支持
    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

• 下载pillow模块

pip install pillow

三、注册应用配置User表

1.注册应用

• dev.py文件

INSTALLED_APPS = [
    ...
    'rest_framework',
    'user',
]

2.配置User表

# 指定自定义的表 : [应用名.表名]
AUTH_USER_MODEL = 'user.User'

四、配置media

1.media路径配置

• 在dev.py文件

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

2. media目录（提示：不用配置，上传文件时会自动生成)

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

五、路由配置

1.主路由配置luffyapi/urls.py：

from django.contrib import admin
from django.urls import path, re_path, include
from django.views.static import serve
from django.conf import settings
urlpatterns = [
    path('admin/', admin.site.urls),

    path('user/', include('user.urls')),

    re_path('^media/(?P.*)', serve, {
     'document_root': settings.MEDIA_ROOT})
]

2.子路由配置 : user/urls.py

from django.urls import path, include
from rest_framework.routers import SimpleRouter
router = SimpleRouter

# 注册ViewSet的路由
# router.register()

urlpatterns = [
    path('', include(router.urls)),
]

六.进行数据库迁移

• cd 到项目根路径下, 因为 manage.py 在项目根路径下

python manage.py makemigrations
python manage.py migrate
