I have found a very good article on how to keep controller simple and how to organize code in different services by using event/listener mechanism from symfony2.
But the issue I have now is following. Let's imagine I have a controller PostController and it has action DeleteAction. This action will fire event post_deleted and there is some other service that should send a private message to the user, whose post has been deleted.
We have now tho distinct actions, that both require access to database and both should succeeded or none of them. The question is, how do I get Symfony2 to pass same connection+transaction to those two services? Should I put connection object in event self, or there is some other mechanism to keep transaction/connection global across during request handling?
BTW, I am using Propel.
