/* v2 version of beego remove the o.Rollback api for transaction operation.
* typically, in v1, you can write code like this:
*
* o := orm.NewOrm()
* if err := o.Operateion(); err != nil {
* o.Rollback()
* ...
* }
*
* however, in v2, this is not available. beego will handles the transaction in new way using
* cluster. the new code is like below:
*
* o := orm.NewOrm()
* if err := o.DoTx(func(ctx context.Context, txOrm orm.TxOrmer) error{
* err := o.Operations()
* if err != nil {
* return err
* }
* ...
* }); err != nil {
* ...
* }
*
* when operation failed, it will automatically calls o.Rollback() for TxOrmer.
* more details see https://beego.me/docs/mvc/model/transaction.md
