我尝试了3天你解决方案让它工作,但我需要帮助。大多数情况下,我做了尝试和错误。如果有人可以给我一个解决方案,我可以对其进行逆向工程并更好地理解cakephp。

我想要的是像这样的索引视图(制作图形): http://www.bilder-upload.eu/show.php?file=fd8e93-1340110385.png

门和钥匙有一个关系,我想列出所有属于1键的门

我有3张桌子:

门(id,title,txt) 键(ID,号,说明) doors_keys(door_id,KEY_ID)

这是我的 key.php

<?php

class Key extends AppModel {
    public $hasAndBelongsToMany = array ('Door');
    public $displayField = 'description';
    // containable
    var $actsAs = array('Containable');
}

door.php

<?php



class Door extends AppModel {
    public $name = 'Door';
    public $belongsTo = array('Building');
    //public $actsAs = array('Containable');
    public $hasAndBelongsToMany = array('Key');
    // validation array wird aufgemacht
    public $validate = array(
    // validation wird für das Datenbankfeld title definiert
        'title' => array(
        // Feld darf nicht leer sein
            'rule' => 'notEmpty' ,
            // Eintrag muss ausgewählt werden
            'required' => true
        ),
        // validation für das DB Feld building_id
        'building_id' => array(
            'rule' => 'notEmpty' ,
            'required' => true
        ),
    );
    // viele türen sind in einem Gebäude-> n:1->$belongsTo
    // in der tabelle doors muss ein fremdschluessel auf die andere datenbank angelegt sein


}

keyscontroller.php (不工作)

class KeysController extends AppController {


public function index() {
    $this->paginate = array(
      'contain' => array(
        // we want to get the key
        'Door' => array(
       // the info i wanna know is in the field txt
          'fields' => array('txt')

        ),

          ),
        );
        $keys = $this->paginate('Key');
    debug($this->set(compact('keys')));
}

index.ctp from keys

<h2>Schluessel selbstgemacht</h2>

<table>
<!-- tr definiert eine Tabellenzeile -->
    <tr>
        <!-- th Überschriften in der Zeile -->
        <th>ID</th>
        <th>Description</th>
        <th>number</th>
    </tr>


<?php foreach($keys as $key): ?>
    <tr>
        <td><?php echo $key['Key']['id'] ?></td>
        <td><?php echo $key['Key']['description'] ?></td>
        <td><?php echo $key['Key']['number'] ?></td>
        <td><?php echo $key['Door']['txt'] ?></td>

        <td>
            <?php echo $this->Html->link('Details', '/keys/view/' . $key['Key']['id']) ?>
            <?php echo $this->Html->link('bearbeiten', '/keys/edit/' . $key['Key']['id']) ?>
            <?php echo $this->Html->link('loeschen', '/keys/delete/' . $key['Key']['id']) ?>
        </td>
    </tr>
<?php endforeach; ?>
</table>

我想这是一个基本问题,但我无法找到解决方案。所以我需要一点帮助。感谢

'recursive' => 1添加到您的Door-&gt; find()以获取相关密钥的数据:

class KeysController extends AppController {
    public function index() {

    $doors = $this->Door->find(
        'recursive' => 1
    );
    $this->set('doors', $doors);

    // Look at the result
    debug($doors);
}

但是,如果模型关系复杂,使用recursive会变得非常混乱。建议您在模型上使用ContainableBehavior
