在做models之前，最好将https://docs.djangoproject.com/en/1.6/ 中的the model layer 细读。
（1）*args和**kwargs。的使用
在Django中经常见到含有这两个参数的函数。*args可代表任意个参数：func(arg, *args)代表这个函数可以有一个或更多个参数。可以理解成一个参数list。**kwargs可以代表任意个K=V形式的参数。大体就是这样。
（2）不经意间，被MySQL的编码折磨。Ubuntu下修改一直有问题。
头痛。折腾了半天还是没搞好，修改/etc/mysql/my.cnf 文件后，重启Mysql服务失败，改回去就可以。但是字符集问题还是没搞好。暂时先用着SQLite3吧。:-(
