php - 在YII2中使用Gii创建 View 和 Controller 时，PHP编译错误

Question

我已经为表创建了Review模型。之后，在为同一表创建 View 和 Controller 时，它显示PHP编译错误。

PHP Compile Error – yii\base\ErrorException

Declaration of app\models\Review::getRelation() must be compatible with yii\db\ActiveRecordInterface::getRelation($name, $throwException = true)

这是完整的错误页面
http://pastebin.com/kf8RFun8。
我已经为表创建了其余的MVC。我只为此错误。

我的模型类(class)
app \ models \ Review
搜索模型类
app \ models \ ReviewSearch
Controller 类
app \ controllers \ ReviewController

注意:在Yii2-Advanced中创建相同代码时，它显示 Error (#64) Internal Server Error
评论模型:

<?php

Answer 1

您需要重命名getRelation()方法，因为您要覆盖yii\db\ActiveRecordInterface::getRelation($name, $throwException = true)。因此，这将导致getRelation方法具有无效声明的异常。
