Question

在向模型调用函数时出现此错误。

Database Error

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 'singleBlockWeekly' at line 1

SQL Query: singleBlockWeekly

这是我的控制器

class BlackoutController extends CalendarAppController
{
    var $uses = array('Studio','Blackout','BlackoutRepeatTypeDetails','Calendar.Event');
    var $components = array('Accesscontrol','RequestHandler');
    function event_checker()
    {
        $start_date = $this->request->data['start_date'];
        $end_date = $this->request->data['end_date'];
        $endsOn = $this->request->data['endsOn'];
        $repeatType = $this->request->data['repeatType'];
        $blockType = $this->request->data['blockType'];
        $frequency = $this->request->data['freq'];
        $repeatDays = $this->request->data['repeatDays'];

        #single type 
        if($blockType == "single"){
            if($repeatType == "weekly"){
                $dates = $this->Blackout->singleBlockWeekly($start_date,$endsOn,$repeatDays,$frequency);
                debug($dates);
                die;
            }
        }
     }
}

这是我的Model

class Blackout extends CalendarAppModel
{
   var $name = 'Blackout';
   var $useTable = false;
   function singleBlockWeekly($startDate,$endDate,$repeatEvery = array(),$freq)
   {
     /*my code here...brevity...*/
   }
}

所以我在这里只是在Blackout模型中调用singleBlockWeekly函数。我想知道为什么即使我在singleBlockWeekly函数上没有任何SQL相关代码，我也会得到奇怪的SQL错误？

非常感谢您的帮助！谢谢！：）

Answer 1

我认为这是一个插件？你不能只把它包含为'Blackout'，你需要使用文档化的插件语法'Calendar.Blackout'。否则，您将加载AppModel实例，当然，该实例没有此方法。

如果你调试了模型实例，你可能已经找到了自己：

debug($this->Blackout);

此SQL错误始终是滥用模型包含语句的指示。

加载模型时出现问题，请尝试此操作

$this->loadModel('Blackout');
$dates = $this->Blackout->singleBlockWeekly($start_date,$endsOn,$repeatDays,$frequency);

CakePHP当您在控制器中时，在模型中调用函数
