php - テーブル`inventory1`.`asset_details`の外部キー制約が失敗します：エラー

Question

これは、show DBinnobdstatusコマンドを実行したときに表示されるエラーメッセージです。私はphpとmysqlに不慣れであり、どんな助けでもありがたいです。前もって感謝します。

データベースにデータを送信すると、情報はアセットテーブルに入力されますが、assert_detailsには入力されません。

編集：すみません、読み間違えました

何が起こるかは、他のテーブルへの外部キーを持つが外部キー ID を指定しないテーブルに行を入れようとすることです。

asset_details テーブルに挿入する前に、外部キーの値を設定する (そしてそれらのキーを他のテーブルに存在させる) 必要があります。

だからあなたの挿入

 INSERT INTO asset_details (asset_type,make, model, serial_number, os,os_version,memory, hdd, processor,notes)
        Values( 'Monitor','Apple ','Mac Book Pro 17 inch ','65655453445545','Macintosh','Snow Lion ','5 gb ','1 TB','Intel i 9','This is Paskale New Mac book pro computer.')

も含める必要がありますphysical_asset_id
