yii2のアクションオブジェクトでないオブジェクトのプロパティを取得しようとしています

Question

私はFrameSearch Modelでクエリをカスタマイズし、findbysqlでクエリを構築しました。また、アクション列をカスタマイズしようとしています。私のgridviewは、アクションの列を除いてよく見えます。 の取得エラー -

exitを追加した後。

解決方法を教えてください。グリッドをフィルタリングするために別のページに渡すアクションカラムボタンからf_nameを取得します。

Answer 1

通常、ArrayHelper::getValueを使用することをお勧めします。例えば

：$modelは、いくつかのオブジェクト（Model又はActiveRecord）、アレイまたは空（=null）である場合

ArrayHelper::getValue($model, 'f_name') 

が動作します。 さらに、デフォルト値の第3引数を持っています。

ArrayHelper::getValue($model, 'f_name', 'value that returned when attribute not found in $model')
