本文主要是介绍Vue + Django API 前后端分离学习笔记 3.3 goods的model设计，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
直接上代码
# -*- coding:utf-8 -*-from datetime import datetimefrom django.db import models

# 这里可以实现用户自定义类别（三级）class GoodsCategory(models.Model):"""商品类别"""CATEGORY_TYPE = ((1, u'一级类目'),(2, u'二级类目'),(3, u'三级类目'))name = models.CharField(default='', max_length=30, verbose_name=u'类别名', help_text=u'类别名')code = models.CharField(default='', max_length=30, verbose_name=u'类别code', help_text=u'类别code' )desc = models.CharField(default='', verbose_name=u'类别描述', help_text=u'类别描述')category_type = models.CharField(choices=CATEGORY_TYPE, verbose_name=u'类目级别', help_text=u'类目级别')

# 用与是否要在导航栏显示的商品类别is_tab = models.BooleanField(default=False, verbose_name=u'是否导航', help_text=u'是否导航')add_time = models.DateTimeField(default=datetime.now, verbose_name=u'添加时间')class Meta:verbose_name = u'商品类别'verbose_name_plural = verbose_namedef __str__(self):self.name#用于存储商品品牌信息

然后 在settings.py中添加app
INSTALLED_APPS = ['django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles','users.apps.UsersConfig','DjangoUeditor','users','goods','trade','user_operation'
]完事~吃饭去
