Question

我有两个表用户（ID，电子邮件，用户名，密码）和帖子（id，user_id，title，body），我在两个模型中有很多关系，现在，当我添加帖子时，它在添加操作中显示用户ID，它可以正常工作，但我想在后添加操作中看到用户名而不是user_id。怎么做？这是我的帖子模型：

class Post extends AppModel {


public $useTable = 'post';

public $displayField = 'title';


public $validate = array(
    'title' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            ),
    ),
    'body' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
        ),
    ),
);

public $belongsTo = array(
    'User' => array(
        'className' => 'User',
        'foreignKey' => 'user_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
);

}

这是我的postcontroller添加功能：

 public function add() {

    if ($this->request->is('post')) {
        $this->Post->create();
        if ($this->Post->save($this->request->data)) {
            $this->Session->setFlash(__('The post has been saved.'));
            return $this->redirect(array('action' => 'index'));
        } else {
            $this->Session->setFlash(__('The post could not be saved. Please, try again.'));
        }
    }
    $users = $this->Post->User->find('list');
    $this->set(compact('users'));
}

Answer 1

尝试更新您的查询，指定您的字段：

   $users = $this->Post->User->find('list', 
                                     array("fields" =>array(
                                                       "User.id",
                                                        "User.email"
                                                      )
                                          )
                                     );

Answer 2

试试这个：

$users = $this->Post->User->find('list', array('fields' => array('User.username')));
