终于学完了rest_framework 这个框架!
这个框架有一些基本组件!最重要的就是看源码!要一个类一个类的去找!按顺序!
并且要自己配置类的时候要先看源类里面的属性,然后覆盖原来属性!不要自定义名称!
要学习好的源码的思想和方式!封装思想要多用!
详情可以参考这个连接 https://www.cnblogs.com/yuanchenqi/articles/8719520.html 拿来主义!
主要看笔记,笔记很是重要!
越努力越幸运!永远不要高估自己!
贴上源码!有空多看看!下面开始进行 vue (前端知识) 后面该是路飞,还有flak!!有空还是得多整理博客!
只是配置好路由部分后访问url出来的页面
