php - Identify whether a managed entity needs to be refreshed based on getReference -

let's assume have entity 'application' , 1 of 'application's' attributes category (it doesn't matter of association type).

so when know category id can call like:

$category = $entitymanager->getreference('category', 1); $application->setcategory($category); $entitymanager->flush();

getreference create proxy can set attribute application. , works without additional sql query sent db getting/setting category.

great!

but wait, when try e.g. name category afterwards, do? thought i'd:

 $category = $entity->getrepository('category')->find(1);  $name = $category->getname();

what's happening don't name error entity cannot found.

i can fight issue explicitly calling:

 $entitymanager->refresh($category);

now reload category database , can name.

my question is:

is there chance identify whether have reference category or initialized / real proxy one?

because in case, have need access category after retrieving reference , not.

if 'refresh' anytime have unnecessary sql statements executed have avoid performancewise and

$entitymanager->getunitofwork()->getentitystate($category)

delivers managed in case.

according this: https://stackoverflow.com/a/26257234/3784145 can check if reference instance of proxy class (doctrine\orm\proxy\proxy) , take action accordingly
