Transaction Handling

Conventional Approach

tx, err := g.DB().Begin(ctx)

if err == nil {
    _, err := tx.Model("book").Data(data).Save()
    if err == nil {
        tx.Commit()
    } else {
        tx.Rollback()
    }
}

Closure Approach (Recommended by the Framework)

g.DB().Transaction(context.TODO(), func(ctx context.Context, tx gdb.TX) error {
    _, err := tx.Model("book").Ctx(ctx).Save(data)
    return err
})
