私のアプリには1つのプライマリデータベースと多くのセカンダリデータベースがあります。データベースごとに2GBの制限があるため、複数のデータベースが必要です。
データは、メインデータベースと多くのセカンダリデータベースの1つに保存する必要があります。プライマリデータベースから、データを保存するセカンダリデータベースがわかります。
私のデータベースは同一ではなく、小さな違いがあります。メインデータベース用のモデルとセカンダリデータベース用の別のモデルを作成しました。
これはエラーです：
CException
SlaveUrl and its behaviors do not have a method or closure named "findByUrl".
これは私が再び戦っているラインです：
$record = SlaveUrl::model()->findByUrl($query);
そしてそれはこのコードにあります：
