from django.db import models
#Create your models here.

class Game(models.Model):
name = models.CharField(max_length=20,verbose_name=‘商品名’)
price = models.IntegerField(verbose_name=‘价格’)
num = models.IntegerField(verbose_name=‘数量’)

1.创建超级用户:python manage.py createsuperuser

2.在子应用的admin.py文件中添加代码，注册表，不然admin控制台没办法管理这个表

from django.contrib import admin
from myapp.models import Game
#Register your models here.
admin.site.register(Game)
