       'model' => $model, 
       'details' => $details 
      ]); 
     } 
    }

當我點擊創建按鈕，它重定向到空白頁，我檢查日誌，它沒有生成任何錯誤日誌。這裏是日誌

外鍵跳過驗證已經解決謝謝，我只是發現了爲什麼驗證錯誤 –

這個問題已經解決了這個錯誤。 –

這個問題，通過這樣的

[['item_id'], 'exist', 'skipOnError' => true, 'targetClass' => Item::className(), 'targetAttribute' => ['item_id' => 'id']],
