Could you tell me if thinkphp's ViewModel can add the Find in SET function? Where to add? Can you give me some more?

I Baidu, found a little about the viewmodel of the explanation AH

public $viewFields = array(        'Blog'=>array('id','name','title','_type'=>'LEFT'),        'Category'=>array('title'=>'category_name','_on'=>'Category.id=Blog.category_id','_type'=>'RIGHT'),        'User'=>array('name'=>'username','_on'=>'User.id=Blog.user_id'),       );       

The function I wrote, where exactly is it added? How do you write it? Can you add it? and a concat.

Thank you for the great God advice!
