从今日开始，公司的新后台系统，我将全部迁移到python的环境下，主要使用了Django与extjs4、jquery1.7的，数据库mysql5.5，容器是nginx。因为不考虑并发因素，所以在这里没有高深的python的线程处理，只是向刚毕业的大学生，几个框架的整合而已，没啥营养，我也是对于python的掌握，觉得Django这框架做的挺好的，模板处理、model层的映射等都比之前玩java时候玩得舒畅。
附件包里面就是简单的一个Django学习的路上的点点滴滴，以及整合了extjs，首先extjs与我而言，玩得比较熟练，所以没有必要在这里，等我把公司的考勤系统原样的搬上来，再来谈后续的事情。
用的开发工具主要是VIM、gedit、eclipse，用了几款python的开发工具诸如pydev、bpython、pycharm等等，还不如使用python shell来得实际。或者有没有童鞋能够推荐，比较geek的工具呢？
提供几个github上方面的例子工程，我的工程一直太大了，一直上传有问题。
才有restful架构方式，view.py中同样使用simplejson开源包，有助于以后从java实现http+json，改变为python编写。
采用pycharm工具
