遇到这样一个错误，我是ci新手，望高手给与解答，谢谢
Fatal error: Call to undefined method News_model::set_news() in /mnt/hgfs/workspace/test/application/controllers/news.php on line 54谷歌翻译我还是懂的但是请看下面代码请问哪里出了错为什么没被定义呢
致命错误：调用未定义的方法News_model:: set_news（）在第54行到/ mnt /生长因子，/工作区/测试/应用程序/控制器/ news.php上
<?php

人家都说了你的news_model里没有定义set_news方法。。。。。。而你的set_news我看了定义在当前类里，那就用$this->set_news()吧。。。/ 你使用 $this->news_model->set_news() ，但是你沒加載 $this->load->model('news_model')
而且你的 news_model 在同個class，可以直接用 $this->set_news()
