"""
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 home

Banner数据表model设计
utils/model.py
from django.db import models
class BaseModel(models.Model):
orders = models.IntegerField(verbose_name='显示顺序')
is_show = models.BooleanField(verbose_name="是否上架", default=False)
is_delete = models.BooleanField(verbose_name="逻辑删除", default=False)
class Meta:
abstract = True
home/models.py
from django.db import models
from utils.model import BaseModel
class Banner(BaseModel):
image = models.ImageField(upload_to='banner', verbose_name='轮播图', null=True, blank=True)
name = models.CharField(max_length=150, verbose_name='轮播图名称')
note = models.CharField(max_length=150, verbose_name='备注信息')
link = models.CharField(max_length=150, verbose_name='轮播图广告地址')
class Meta:
db_table = 'luffy_banner'
verbose_name = '轮播图'
verbose_name_plural = verbose_name
