symfony - Some property object are null -

i have problem , of course dont understand :) (and of course im french :)

on table "evenement" have user linked. , when :

$repository = $this->getdoctrine()->getmanager()->getrepository('appbundle:evenement'); $evt = $repository->findonebyid($evt); dump($evt) 

all ok, can read evt, when in profiler click on child object "user", property null (except id, usermail, mail, password)

and same thing when :

dump($evt->getuser()); 

why property not filled ?

thank , sorry english.

it's lazy loading. properties not beeing read db unless need them.

try following:

$repository = $this->getdoctrine()->getmanager()->getrepository('appbundle:evenement'); $evt = $repository->findonebyid($evt); $evt->getuser()->getroles(); // ot whatever properties user has. dump($evt) 

in case, dump show property populated.
