我正在为一个遗留的CakePHP2.5应用程序构建一个控制器，该控制器加载一个现有的模型，然后从该模型的表中查询数据，当调用该控制器时，我一直收到下面的错误消息

Missing Database Table Error: Database table supports for model Support was not found.

下面是支持控制器代码

<?php
class SupportController extends AppController{
    public $name='Support';
    public $helpers = array('Html','Form');

    public function index(){
        $this->loadModel('Applicant');

        $appConditions = array(
            'fields'=>array('first_name','surname','middle_name','maiden_name','date_of_birth'),
            'order'=>array('Applicant.created DESC')
        );

        $this->paginate['Applicant'] = $appConditions;
        $applicationData = $this->paginate('Applicant');

        $this->set(compact('applicationData'));

        // $this->set('applicants', $this->Applicant->find('all'));
    }
}

控制器不需要模型，因为它假定从已经存在的申请人模型加载数据。
