我对 cakephp 中的 HABTM 关系有疑问。我有 2 个模型 Campaign 和 Person 我创建了 3 个数据库表campaings、persons 和campaigns_persons。
模型如下所示：

活动

class Campaign extends AppModel {

    var $name = 'Campaign';
    var $displayField = 'nombre';
    var $belongsTo = array(
        'Client' => array(
            'className' => 'Client',
            'foreignKey' => 'client_id'
        ),
        'Template' => array(
            'className' => 'Template',
            'foreignKey' => 'template_id'
        )
    );
    var $hasAndBelongsToMany = array(
        'Persona' =>
        array('className' => 'Person',
            'joinTable' => 'campaigns_persons',
            'foreignKey' => 'campaign_id',
            'associationForeignKey' => 'person_id',
            'with' => '',
            'conditions' => '',
            'order' => '',
            'limit' => '',
            'unique' => true,
            'finderQuery' => '',
            'deleteQuery' => '',
            'insertQuery' => ''
        )
    );
}

人

class Person extends AppModel {

    var $name = 'Person';
    var $displayField = 'name';
    var $belongsTo = array(
        'Client' => array(
            'className' => 'Client',
            'foreignKey' => 'client_id',
        ),
    );
}

控制器如下所示：

        $this->Campaign->create();
    if ($this->Campaign->save($this->data)) {
        $this->Session->write('campaign_id', $this->Campaign->id);
        $this->Session->setFlash(__("Listado de clientes agregado", true));
        return true;
    }//fin saveAll

它向我抛出了这个错误：

    Fatal error: Cannot access empty property in
    1   0.0012  372600  {main}( )   ..\index.php:0
    2   0.1148  4012344 Dispatcher->dispatch( ) ..\index.php:86

    7   2.4743  9845568 Model->save( )  ..\campaigns_controller.php:281

我不知道发生了什么。
