Doctrine 2, query inside entities

Question

How do I perform queries in an entity?

namespace Entities\\Members;

/**
 * @Entity(repositoryClass=\"\\Entities\\Member\\MembersRepository\")
 * @Table(name         


        

Answer 1

Your ArrayCollection already implements a filter() method, you need to pass a Closure to get it to work your entities (here, the commentEntries).

$idsToFilter = array(1,2,3,4);

$member->getComments()->filter(
    function($entry) use ($idsToFilter) {
       if (in_array($entry->getId(), $idsToFilter)) {
           return true;
       }

       return false;
    }
); 

(not tested)

Note that such method will iterate and eager load over all your Comments, so in case where a User has a lot it may be a big bottleneck;

In most case, you want to use a custom repositories, where you can place such logic.

As timdev suggested, you can create a MemberService which will wrap such call by being aware of the EntityManager.

Separating Entities from the Peristance Layer is a big improvement over Doctrine 1, and you should not break that rule.
