Question

这是我的模特

<?php
class Survey extends AppModel {

    // model associations
    public $belongsTo = array( 
    'Organisation' => array( 
      'className' => 'Organisation', 
      'foreignKey' => 'organisation_id' 
    ),
    'Account' => array( 
      'className' => 'Account', 
      'foreignKey' => 'account_id' 
    ),
    'User' => array( 
      'className' => 'User', 
      'foreignKey' => 'user_id' 
    ),
    'Country' => array( 
      'className' => 'Country', 
      'foreignKey' => 'country_id' 
    ),
    'Currency' => array( 
      'className' => 'Currency', 
      'foreignKey' => 'currency_id' 
    )
  );

}
?>

这是我的控制器

<?php
class SurveysController extends AppController {
public $components = array('Session');
public $uses = array('Report', 'Mycase', 'Workflow');

public function add($type = null, $id = null) {

    if (!$id || !$type) {
            throw new NotFoundException(__('Invalid link'));
        }

    $type = Inflector::camelize($type);

    // this populates the form select for country allowing the country from the report to be prepopulated
    $countries = $this->$type->Country->find('list');
    $this->set(compact('countries'));

    // this populates the form select for currency
    $currencies = $this->Survey->Currency->find('list');
    $this->set(compact('currencies'));

    $resources = $this->$type->find('first',
        array(
        'conditions' => array($type.'.id' => $id, $type.'.account_id' => $this->Session->read('Auth.User.account_id')),
        'recursive' => -1 //int
        ));
    if (!$resources) {
            throw new NotFoundException(__('You are not authorised to access that location'));
        }
    $this->set('resources', $resources);

}

}

错误在于控制器中的这行代码

$currencies = $this->Survey->Currency->find('list');

我有一个带有Currencies的数据库表，我正在尝试将其填充到选择中的Survey视图中。我已检查模型和控制器是否正确命名。我的关联类似于我也使用的国家/地区选择，它正常工作，但我在货币查询中收到此错误，我一直在尝试调试几个小时。

Fatal Error
Error: Call to a member function find() on a non-object

错误消息告诉您要查看的位置： SurveysController.php 的第29行。

您有可能在未包含的模型上调用find()。如果是Survey，则需要将其添加到控制器中的$uses属性，以便加载它。

无法调试cakephp错误在非对象上调用成员函数find（）
