USAGE

Examples

entity_change_watch:
    classes:
        Entity\MyEntity:
            create:
                - {name: 'MyEntityService', method: 'doSomethingBeforeFlush', flush: false}
            delete:
                - {name: 'MyEntityService', method: 'doSomething'}
            update:
                all:
                    - {name: 'MyEntityService', method: 'doSomething'}
                properties:
                    property1:
                        - {name: 'MyEntityService', method: 'doSomething'}
                    property2:
                        - {name: 'MyEntityService', method: 'doSomethingElse'}

class MyEntityService
{
    public function doSomething(MyEntity $myEntity)
    {
        /*
        
        do something
        */
    }
    
    public function doSomethingBeforeFlush(MyEntity $myEntity)
    {
        /*
        
        do something before the flush
        */
    }
    
    public function doSomethingElse(MyEntity $myEntity, array $changedProperties, EntityManagerInterface $entityManager)
    {
        /*
        
        do something else
        */
    }

Callbacks services definition

All callback services must be tagged with actiane.entitychangewatch.callback

Callbacks method

Please note that the orders of the arguments matter

The first argument is the entity The second argument $changedProperties contains an array with all the changes applied to the entity. The third argument $$entityManager is the entityManager

A callback is called after the flush, you can not execute another flush in this method.

If you whish to add or modify entities, you need to set the flush parameter to false

 - {name: 'MyEntityService', method: 'doSomethingBeforeFlush', flush: false}

If you create and persist a new entity in this callback, then calling EntityManager#persist() is not enough. You have to execute an additional call to $unitOfWork->computeChangeSet($classMetadata, $entity).

Changing primitive fields or associations requires you to explicitly trigger a re-computation of the changeset of the affected entity. This can be done by calling $unitOfWork->recomputeSingleEntityChangeSet($classMetadata, $entity).
