Added support for tagging entity listeners, without the need to map the listener

[kimhemsoe]

Adds support for tagging entity listeners, defining entity and method.

Every listener service is created when the entitymanager is created for now. A solution could be marking the services lazy as suggested by @Ocramius and @stof in #223

Very nice 👍

@stof Is this something you can accept into the bundle and what do you think about it ?

[Nemo64]

OK, I'd really like to have that right now (if it works like described)

In keeping with conventions of other event listeners and subscribers the config property type should probably be renamed to event

- { name: doctrine.orm.entity_listener, entity_manager: em2, entity: My/Entity2, event: preFlush, method: preFlushHandler}

But otherwise I would really love to see this feature added ASAP

Would love to be able to use this feature!

[hacfi]

👍 Trying to implement this feature myself I came across this PR. Would love to see this getting merged.

[kimhemsoe]

@hacfi I never really tested this in a real app. It should work but im not 100% sure. Have you or anyone else tried it ?

[hacfi]

@kimhemsoe Debugging this at the moment..looks like the entity listener isn’t added properly to the class metadata.

[kimhemsoe]

@hacfi I have done a rebase to make it bit easier.

[hacfi]

this should be

            $attributes['entity'],
            $serviceDef->getClass(),

See https://github.com/doctrine/doctrine2/blob/master/docs/en/changelog/migration_2_5.rst#events-add-api-to-programatically-add-event-listeners-to-entity

[kimhemsoe]

Fixed

[hacfi]

I don’t understand this part..using ORM 2.5.0 the listener is missing in the attachToListener method.

[hacfi]

Thanks for the quick update @kimhemsoe !

I think this should be

if (version_compare(Version::VERSION, "2.5.0-DEV") > 0) {

instead. doctrine.orm.listeners.attach_entity_listeners.class isn’t available before 2.5 !?

[kimhemsoe]

You are correct, i was a bit to fast in the rebase.

[hacfi]

@kimhemsoe Perfect...works as expected now.

As @chasen suggested the name event is more consistent that type. What do you think?

[kimhemsoe]

The name "type" is from doctrine ORM, but "event" would be fine with me.

[hacfi]

Great! Thanks so much for this @kimhemsoe...I almost started writing a custom annotation for this 😜

[kimhemsoe]

You welcome @hacfi and thanks for the help. I will merge when travis and Scrutinizer returns green.

@kimhemsoe Updating my current project to get the latest master..so useful I don’t want to wait :)
