There are 2 many-to-many associations between the users and comments. Both use another join-table. The join-tables user_favorite_comments and user_read_comments must be specified. Otherwise the default "user_comment" is taken twice. See https://groups.google.com/forum/#!topic/doctrine-user/Kti36_n6490 and https://groups.google.com/forum/#!topic/doctrine-user/TYwafhgYiSU

Doctrine 2 is an object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects. It sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. This provides developers with a powerful alternative to SQL that maintains flexibility without requiring unnecessary code duplication.
