我认为,可以采用以下模型中的<代码>虚拟领域和<编码> 外地<>/代码>特性。

在您的模型中,确定了一个全名的虚拟领域:

public $virtualFields = array(
     full_name  =>  CONCAT(User.first_name, " ", User.last_name) 
);

如果你现在开张, 填满姓名的外地人员应当能够找到一份用户名单,其中附有<代码>$this->User->find(清单), 您可以在无问题的情况下使用。

public $displayField =  full_name ;

或

public $displayField =  User.full_name ;

补贴自动发放。

另一种解决办法是使用《面包一套: 共同建设你们所需要的东西......

$users = $this->User->find( all ,array( fields  => array( first_name , last_name , id )));

$user_list = Set::combine($users,  {n}.User.id , array( {0} {1} ,  {n}.User.first_name ,  {n}.User.last_name ));

成果将探讨这样的问题:

array(
 [2] =>  First Last ,
 [5] =>  Bob Jones 
)

就我而言,Seta:combine是前进的道路,因为我不得不处理相关领域的分类问题,例如:

$bancos_enteros = $this->Financiacion->Banco->find( all , array(
   fields  => array( Empresa.codigo_contable , Empresa.nombre_corto ,  Banco.id ),
   order  => array( Empresa.codigo_contable  =>  asc ),
   recursive  => 1
));
$bancos = Set::combine(
   $bancos_enteros,
    {n}.Banco.id ,
    array(
        {0} {1} ,
        {n}.Empresa.codigo_contable ,
        {n}.Empresa.nombre_corto 
     )
 );

返回

    array(
    (int) 14 =>  57200002 Caixa ,
    (int) 15 =>  57200003 Sabadell ,
    (int) 3 =>  57200005 BBVA ,
    (int) 16 =>  57200006 Deutsche Bank ,
    (int) 17 =>  57200007 Popular ,
    (int) 18 =>  57200009 March ,
    (int) 26 =>  57200010 Bankinter ,
    (int) 4 =>  57200011 Santander 
)

......

$this->Financiacion->Banco->Empresa->virtualFields = array(
     codigo_nombre  =>  CONCAT(Empresa.codigo_contable,Empresa.nombre_corto) 
);
$this->Financiacion->Banco->virtualFields[ codigo_nombre ] =  $this->Financiacion->Banco->Empresa->virtualFields[ codigo_nombre ];
$bancos = $this->Financiacion->Banco->find( list , array(
    fields  => array( Banco.id , Banco.codigo_nombre ),
    order  => array( Banco.codigo_nombre  =>  asc ),
    recursive  => 1
    )   
);

如果我不首先删除虚拟领域的话,我就在以下询问中发现错误:

unset($this->Financiacion->Banco->Empresa->virtualFields);
unset($this->Financiacion->Banco->virtualFields);

Update for CakePHP 4x.

// Model/Entity/{entityName}.php
// "fname, lname, email" are my DB field names
protected function _getFullName()
{
    return $this->_fields[ fname ] .     . $this->_fields[ lname ];
}

protected function _getLabelDropdown()
{
    return $this->_fields[ fname ] .     . $this->_fields[ lname ] .   (  . $this->_fields[ email ] .  ) ;
}

...


// Model/Table/{tableName}.php
public function getUserList()
{
    return $this->find( list , [
         keyField  =>  uuid ,
         valueField  => function ($user) {
            return $user->get( full_name ); // It s _getFullName()
            // or 
            // return $user->get( label_dropdown ); // It s _getLabelDropdown()
        }
    ])->where([
         is_delete  => 0,
         is_active  => 1,
    ]);
}

// Controller/{ControllerName}.php
public function add()
{
  ...

  $this->set( user_list , $this->Users->getUserList());

  ...
}

// View
<?= $this->Form->control( role_uuid , [
    options  => $user_list,
    class  =>  form-select ,
    id  =>  user_uuid ,
    label  => __( Choose User ),
    default  => DEFAULT_USER
]); ?>
