Symfony2 Doctrine Get reference based on attribute

in my Symfony2/Doctrine2 project I have an entity Person which has a birth date. I have another entity Agegroup which stores a name and some more information for a group based on the age in years.

Example:
Person Name: xy Date: 1980-05-06
Agegroup: From: 1 To: 10
Agegroup: From: 11 To: 20
Agegroup: From: 21 To: 30

I want to get the Agegroup which a person currently belongs to, from within the entity (based on current date).

i.e. :$person->getCurrentAgeGroup()

Therefore I would have to access another repository class from within the entity, which is obviously not a good thing to do.

Is there a way to implement this kind of functionality?

I read Using EntityManager inside Doctrine 2.0 entities which could be a solution to the problem. Unfortunately I didn't find a solution to implementent this. Do I have to inject the service somehow into the entity?

Maybe there are other best practices for this kind of problem?

It is not good style to put the entity manager into your entities. A better approach would be to create a custom AgegroupRepository that has a method getAgegroup(Person $person)

Another approach would be to make the age group a property of Person (with getters and setters), create a custom PersonRepository and modify the find() method to instantiate the correct instance of Agegroup when looking for a person.

Your entity objects should only store data and business rules and should not concern themselves with the storage of the information. This is what repositories are for.
