🍖06 创建应用(app),表(model)及路由配置

一.创建应用 : user

• 进入到 apps 目录下执行命令

python ../../manage.py startapp user

二.创建 user 应用对应的 model

• 进入 app---->user---->model

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.注册应用并配置User表

1.注册应用

• develop.py 文件中

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 develop.py 文件中配置

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

2.media 目录配置

├── 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 luffyapi import settings
urlpatterns = [
    path('admin/', admin.site.urls),
    path('user/', include('user.urls')),
    re_path('^media/(?P<path>.*)', serve, {'document_root': settings.develop.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
