示例1: HandlePanic

func (self *QbsDefaultOrmTransactionPolicy) HandlePanic(tx *qbs.Qbs, err interface{}) (interface{}, error) {
log.Printf("got panic, rolling back and returning 500 to client (%v)\n", err)
if rerr := tx.Rollback(); rerr != nil {
panic(rerr)
}
return nil, HTTPError(http.StatusInternalServerError, fmt.Sprintf("panic: %v", err))

//back or if it should be committed. It rolls back when the result value is
//a non-http error, if it is an Error and the status code is >= 400.
func (self *QbsDefaultOrmTransactionPolicy) HandleResult(tx *qbs.Qbs, value interface{}, err error) (interface{}, error) {
if err != nil {
switch e := err.(type) {
case *Error:
if e.StatusCode >= 400 {
rerr := tx.Rollback()
if rerr != nil {
return nil, rerr
