Use ID for determining Model equality #320

Closed KaptajnKold closed 9 years ago

KaptajnKold commented 9 years ago

I find it surprising that model equality is determined by object equality. To me, it is part of the semantics of a model (or an Entity in the DDD parlance) is that equality is determined by ID. Same ID, same entity.

I propose that an attribute declared with id: true, enables this behaviour.

You can do include Equalizer.new(:id) in your models to achieve that.

Cool :)
