Thinkphp3.2 View model query bool (false) solution-php Tutorial

Thinkphp3.2 View model query bool (false) to solve

  array('picTitle','picToken','picCategroy','picAuthor','picPostTime','_type'=>'LEFT'),        'picture_attachment' =>array('pictureid','pictureurl','creattime','_on'=>'picture.picToken = picture_attachment.pictureid'),    );}

Two picture and picture_attachment tables
I use the D method to instantiate PicView written in the controller. Is this a real table name in the database?

    public function  Pic(){         $PicModel =D('PicView');        dump($PicModel);         $s =   $PicModel->select();        dump($s);    }

# Initialize the PicView model. if the PicView class exists, call and initialize it. if the class does not exist, initialize the model based on the table name $ PicModel = D ('picview '); # The SQL statement used to output all data is # SELECT * FROM PicView $ s = $ PicModel-> select ();

PHP beginners are not recommended to directly look at the framework!

Thank you! I have solved the problem that the sorting of fields in the two tables is different, which makes other good frameworks easy to use.
