Question

我想知道我在这里做错了什么。

我有这种关系

Proprietaire模型：

var $belongsTo = array(
    'Residence' => array(
        'className' => 'Residence',
        'foreignKey' => 'residence_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
);

住宅模型

var $hasMany = array(
'Proprietaire' => array(
        'className' => 'Proprietaire',
        'foreignKey' => 'residence_id',
        'dependent' => true,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    )
);

在proprietaire我尝试获得这样的居住名称

<?php
class ProprietairesController extends AppController {

var $name = 'Proprietaires';

   function index() {
     $this->Proprietaire->recursive = 1;
 $this->set('proprietaires', $this->paginate());

 $residences = $this->Proprietaire->Residence->find('list');
 $this->set(compact('residences'));
   }

}
?>

但在我的proprietaire观点

    <?php   foreach ($proprietaires as $proprietaire): ?>
        <?= print_r($proprietaire['Residence'])?>
        <tr <?= $this->Cycle->css(array('list-line-odd', 'list-line-even'),true); ?>>
            <td><?php echo $proprietaire['Proprietaire']['nom']; ?>&nbsp;</td>
            <td style="text-align: center;"><?php echo $proprietaire['Proprietaire']['prenom']; ?>&nbsp;</td>
            <td style="text-align: center;"><?php echo $proprietaire['Residence']['nom']; ?>&nbsp;</td>
            <td class="actions">
                <?php echo $this->Html->link(__('Modifier', true), array('action' => 'edit', $proprietaire['Proprietaire']['id'])); ?>
                <?php echo $this->Html->link(__('Supprimer', true), array('action' => 'delete', $proprietaire['Proprietaire']['id']), null, sprintf(__('&Ecirc;tes-vous certain de vouloir supprimer # %s?', true), $proprietaire['Proprietaire']['id'])); ?>
            </td>
        </tr>
    <?php endforeach; ?>

print_r（proprietaire ['Residence']给我一个空数组。

Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1 Array ( ) 1

什么是坏事？我的表关系？

感谢您的帮助。

Answer 1

确保在住宅模型中设置了displayField属性

var $displayField = 'nom';

或者像这样找到：

$residences = $this->Proprietaire->Residence->find('list', array('Residence.id', 'Residence.nom'));

否则检查您的查询，将调试级别设置为2并在布局或视图中添加以下内容

<?php echo $this->element('sql_dump'); ?>

cakephp表关系为空
