php - CakePHP 3.0 - $this->Model->get($id) 引发 MySQL 错误

Question

我正在尝试在 Controller (PropertyController.php)内创建一个删除函数，该函数将从数据库中删除一条记录，然后触发一个事件。

但是它抛出了这个错误:

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an
error in your SQL syntax; check the manual that corresponds to your MySQL 
server version for the right syntax to use near 'get' at line 1

堆栈跟踪:

    CORE/Cake/Model/Datasource/DboSource.php line 426 → DboSource->_execute(string, array)

    CORE/Cake/Routing/Dispatcher.php line 167 → Dispatcher->_invoke(PropertyController, CakeRequest)
    APP/webroot/index.php line 118 → Dispatcher->dispatch(CakeRequest, CakeResponse)

我可以通过 find() 访问记录，但由于某种原因不能使用 get() 访问记录。

/属性/删除/2000

PropertyController.php 中的函数:

public function delete($propertyAgentRef = null) {

    // Get property entity
    $property = $this->Property->get($propertyAgentRef);

    // Delete
    $result = $this->Property->delete($property);

}

Property.php(模型)

class Property extends AppModel {
   public $primaryKey = 'agent_ref';
   public $hasMany = array(
  'PropertyMediaImage' => array(
      'className' => 'PropertyMediaImage',
      'foreignKey' => 'agent_ref',
      'dependent' => true,
        'cascadeCallbacks' => true
  ),
  'PropertyMediaFloorPlan' => array(
      'className' => 'PropertyMediaFloorPlan',
      'foreignKey' => 'agent_ref',
      'dependent' => true,
        'cascadeCallbacks' => true        
  ),
  'PropertyMediaDocument' => array(
      'className' => 'PropertyMediaDocument',
      'foreignKey' => 'agent_ref',
      'dependent' => true,
        'cascadeCallbacks' => true        
  ),            
  'PropertyMediaVirtualTour' => array(
      'className' => 'PropertyMediaVirtualTour',
      'foreignKey' => 'agent_ref',
      'dependent' => true,
        'cascadeCallbacks' => true
  )
);
}

我需要在模型 Controller 中添加 get 方法吗？或者这可能是我的自定义主键的问题？

Answer 1

您的代码显示您正在使用 CakePHP 2.x，但您尝试使用它的方式是 CakePHP 3。CakePHP 2.x 不具有实体对象。 Cake2 中现有的模型方法都没有作为 SQL 执行，这就是错误的原因。

仔细检查您正在阅读的文档，如果您使用 Cake2，请确保遵循 2.x 文档。

提出问题时始终说出您正在使用的确切 CakePHP 版本。
