Question

我正在尝试从关系函数本身缓存关系模型。我想知道这是否是最佳做法：

public function getProgram()
    {
        return $this->hasOne(Program::className(), ['id' => 'program_id'])->cache(5);
    }

问题是它似乎可以在我的本地机器上工作，它有php 7.1，但是在生产上出错，它有php 5.6。错误是：

消息：

yii\base\InvalidParamException: common\models\MyEvent has no relation named "program".

跟踪：
