テーブル内のmysqlデータベースから1つのセルを更新しようとしていますが、グローバル変数をセルに渡すことができません。現在、mysqlデータベースから整数を取得しています。次に、グローバルに定義しようとします。次に、変数をmystruct(テーブルの構造)に渡し、最後にmystructをテーブルに適用すると、エラーが発生しますAttributeError: 'Window' object has no attribute 'struct1'
。 self.mystruct1が最初にで使用されるので理由を知ってください__init__
。代替手段はありますか。理解するために以下のコードを見てください。*注意位置は関係ありません
