Symfony2: get Doctrine in a generic PHP class

Question

In a Symfony2 project, when you use a Controller, you can access Doctrine by calling getDoctrine() on this, i.e.:

Answer 1

After checking the symfony2 docs i figured out how to pass your service in a custom method to break the default behavior.

Rewrite your configs like this:

services:
my_mailer:
    class: Path/To/GenericClass
    calls:
         - [anotherMethodName, [doctrine.orm.entity_manager]]

So, the Service is now available in your other method.

public function anotherMethodName($entityManager)
{
    // your magic
}

The Answer from Ondrej is absolutely correct, I just wanted to add this piece of the puzzle to this thread.
