func Transaction

func Transaction(b *gorp.DbMap, f TransactionFunc) error

Transaction wraps your calls in a gorp.Transaction. If the call should fail with an error it will perform a rollback. Otherwise the transaction will be committed.

Usage: ``` import (

dblib "github.com/chef/automate/lib/db"
"github.com/go-gorp/gorp"
_ "github.com/lib/pq"

)

type postgres struct {
  *gorp.DbMap
}

func (db *postgres) InsertData(data) error {
  return dblib.Transaction(db.DbMap, func(tx *gorp.Transaction) error {

    // Add here all your transactions (check all errors)
    tx.Insert(deploy)
    tx.Update(deploy)
    tx.Insert(deploy)
    tx.Delete(deploy)

    return nil
  })
}

```
