よくある思い込み

gorm.Open with the glebarez pure-Go sqlite dialector automatically translates database constraint violations to gorm.ErrDuplicatedKey or gorm.ErrForeignKeyViolated by default without setting TranslateError

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• sqlite.Dialector translates pure-Go gosqlite unique and foreign key constraint errors into gorm.ErrDuplicatedKey and gorm.ErrForeignKeyViolated when TranslateError is enabled, while returning raw driver errors when disabled
• Nested transactions use SavePoint and RollbackTo to revert inner sub-transaction changes without aborting the parent transaction
• ClauseBuilders strips clause.Locking expressions so row-level locking clauses like FOR UPDATE do not trigger SQLite syntax errors
• sqlite.Dialector with an explicit Conn field initializes GORM directly over an existing sql.DB connection pool without opening a new DSN
