from django.db import models

# Create your models here.
class Book(models.Model):
    nid = models.AutoField(primary_key=True)  # 自增id(可以不写,默认会有自增id)
    title = models.CharField(max_length=32)
    publishDdata = models.DateField()  # 出版日期
    price = models.DecimalField(max_digits=5, decimal_places=2)  # 一共5位,保留两位小数

    #一个出版社有多本书,关联字段要写在多的一方
    # 不用命名为publish_id,因为django为我们自动就加上了_id
    publish = models.ForeignKey("Publish")  #foreignkey(表名)建立的一对多关系
    # publish是实例对象关联的出版社对象

 1 """周末作业aaa用图书管理系统django实现 URL Configuration

 3 The `urlpatterns` list routes URLs to views. For more information please see:
 4     https://docs.djangoproject.com/en/1.11/topics/http/urls/
 5 Examples:
 6 Function views
 7     1. Add an import:  from my_app import views
 8     2. Add a URL to urlpatterns:  url(r‘^$‘, views.home, name=‘home‘)
 9 Class-based views
10     1. Add an import:  from other_app.views import Home
11     2. Add a URL to urlpatterns:  url(r‘^$‘, Home.as_view(), name=‘home‘)
12 Including another URLconf
13     1. Import the include() function: from django.conf.urls import url, include
14     2. Add a URL to urlpatterns:  url(r‘^blog/‘, include(‘blog.urls‘))
15 """
16 from django.conf.urls import url
17 from django.contrib import admin
