user模块User表

创建user模块

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
先切换到app目录下
>: python ../../manage.py startapp user

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

注册user模块，配置User表：dev.py

# 注册
INSTALLED_APPS = [
    # ...
    'user',
]

# 自定义User表
AUTH_USER_MODEL = 'user.User'

配置media

media配置：dev.py

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

media目录配置

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

主路由：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<path>.*)', serve, {'document_root': settings.MEDIA_ROOT})
]

子路由：user/urls.py

from django.urls import path, include
from utils.router import router

# 注册ViewSet的路由
# router.register()

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

数据库迁移

"""
1）去向大luffyapi所在目录的终端

2）安装pillow模块
pip install pillow

3）数据库迁移
python manage.py makemigrations
python manage.py migrate
