php - Doctrine refresh copy of entity -

-

i have customeraccount entity. after entity has had changes made via form, before entity has been persisted database, need fetch new copy of same customeraccount entity exists in database. reason need want fire off changed event both old , new data in service.

one hack used $oldaccount = unserialize(serialize($account)); , passing old service, thats hackish.

is possible?

update

update 2

i added solution ended using @ bottom. i'm not happy because feels hackish, gets job done , allows me move on.

it depends.

this, however, lead strange behaviour "slip" out of control:

  • you can't persist again detached object
  • if try persist object related ("linked") detached entity run troubles (and difficult debug)

so, why don't try php built-in clone function? maybe more suitable , save lot of debugging

code example:

$em = $this->getdoctrine()->getmanager(); $fetched_entity = $em->findonbyid(12); $cloned_entity = clone $fetched_entity; //and on ...
