use think\Model;

class Admin extends Model
{
public function profile(){
return $this->hasOne("Profile")->bind{[
'profile_id' =>'id',
]};
}
｝

这是MODEL内容

为什么用$data = $model->select();
返回内容

Array
(
[0] => app\common\model\admin\Admin object
(
[connection:protected] => Array
(

在SELECT()->toArray()出错，和教程说的不一样啊。
