企业网站定制开发Python图书管理系统（终章）

文章目录

  
  
  

前言

  

企业网站定制开发上次写了用MySQL企业网站定制开发完成数据存储的图书管理系统，
企业网站定制开发这次我将把各个模块划企业网站定制开发分为系统的各个功能，企业网站定制开发通过框架与前端进行数据交互。企业网站定制开发做成一个小型的完整网页项目。

  
  
  

企业网站定制开发总的项目布局

  

企业网站定制开发项目布局很重要，企业网站定制开发什么类型的文件就放在企业网站定制开发对应类型的文件夹下。


blueprints ：企业网站定制开发里放各个功能模块。

static ：里面放css用的图片等美化网页的文件。（这个项目只是练手，前端就没细搞，所以我这个文件夹里是空的）

templates：里面放前端代码。

app.py：作为一个主文件运行，用来启动网站。

config.py：其实app.py下还应有个config.py作为配置文件。设置这样一个专门放项目配置的配置文件，就不用在每个项目中写几十甚至上百条配置语句了，配置时只需调用此文件即可。（这个项目很小，几乎用不到配置，所以没弄这个）

  
  

数据库层面：

这些是项目中用来存储数据的表。


  
  
  

效果展示

  
1.未登录时

有个提示登陆的弹窗，点确定就进入了


没有账号的需要注册


注册完成后就可以登录了
  

2.登录

若用普通学号（2028124001）登录，则功能较少

PS：项目较小，普通人登录的功能没怎么弄，就只能登录、注销和查看图书信息，更多功能都在管理员登录那。

注销，换个账号登录

就又回到了刚刚没登陆前的页面

这次用管理员学号（2028124078）登录

  
3.功能操作

管理员可以操作三个表：图书列表、已借出的书、借阅人信息，并可以对这三个表的数据进行“增删查”。（暂时没有“改”，等会了Ajax再加上）

具体操作就不一一展示了。

  
  
  

全部代码

  

话不多说，上代码！！！
  

blueprints里：

AllBooks.py

其实该用模板继承呢，会大大减少重复代码量。我弄的这太冗余了！

总结

  
这是我学了一个月时间做出来的小项目，功能很少，长得很丑，算是个半成品，跟各位大佬的肯定比不了，大家也就将就着看看，未来要是有时间还是会翻出来优化它的。

我之前学的很浅，只会用语言完成学校布置的一些简单题目而已，并不会用语言做其他东西。
机缘巧合之下，铁甲小宝大佬带我走进编程的世界，引领我学习。没有他，我现在还是个天天傻玩的憨批。

这个项目是我的第一个编程项目，算是正式入门了，今后我会更加努力学习的！！！

最后，再次感谢铁甲小宝大佬，祝大佬如愿以偿进大厂！！！
