Stark组件!
2018-10-21 20:21:41
功能简介:
        由于原来做的stark有bug,所以修改了一下,setting注册就可以使用完美仿照admin
        *********
        1. 使用方法和Django的admin一样,需要在stark里面注册,详情看app01/stark.py
        2. 实现了对不同表的url的各级分发
        3. 用户可以自定义配置表的现实信息 详情可以看app01/stark.py
        4. 实现了对表添加数据pop的功能!
        5. 最强大就是,你可以拿去直接用,和admin一样,而且不需要超级用户!
