模型里这么写的

<?phpnamespace Home\Model;use Think\Model\ViewModel;class PicViewModel extends  ViewModel{    public $viewFields =array(       'picture'=> array('picTitle','picToken','picCategroy','picAuthor','picPostTime','_type'=>'LEFT'),        'picture_attachment' =>array('pictureid','pictureurl','creattime','_on'=>'picture.picToken = picture_attachment.pictureid'),    );}

picture和picture_attachment两张表 
控制器里这么写的 我用D方法实例化PicView 这个是必须在数据库里真实的表名么
    public function  Pic(){         $PicModel =D('PicView');        dump($PicModel);         $s =   $PicModel->select();        dump($s);    }


返回的一些错误

回复讨论(解决方案)

# PicView 模型初始化,如果该PicView类存在则调用并初始化,如果不存在 ,则根据表名初始化模型         $PicModel =D('PicView'); #输出所有数据 实际执行的SQL语句是# SELECT * FROM PicView         $s =   $PicModel->select();

PHP初学者不建议直接看框架!

谢谢好心人 我已经解决了 就是两个表的字段排序不一样造成了  其他的还好 框架使用方便点
