Python基于mysql+Django框架图书管理系统源代码(含mysql文件)

项目前台和后台界面模板都是自己编写，前台采用Bootstrap框架UI,后台EasyUI框架UI,没有采用Django自动生成的那个后台管理，因为那个后台实在是太丑了，丑得惨不忍睹！整个项目主要负责图书信息的添加，修改，多个条件组合查询，删除。虽然系统功能不是很复杂，不过这是一个很好的学习案例，包括了常用字段的设计，比如字符串，浮点型，整型，日期型，图片型，富文本字符串型，文件型和下拉框外键关联型，囊括了所有商业项目设计需要的字段类型，通杀所有商业系统设计原理！当然也是学习的不二选择，好东西值得分享，强烈推荐.后台登录用户名密码均为a。
系统实体对象：
图书类型：图书类别，类别名称，可借阅天数
图书：图书条形码，图书名称，图书所在类别，图书价格，库存，出版日期，出版社，图书图片，图书简介，图书文件。
