Django（图书管理系统）

图书管理系统

注意事项

1、models 要创建好，规划好自己的表，以及各种表关系

2、url正则要写好

3、settings的配置

4、利用bootstarp 进行布局更漂亮哦

5、注意orm  各种类型的转换还有取值。

6、模板语法

下面上菜

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
