Ember has find() method to issue GET towards the server. You can do it with id or without.
I am looking at the official guide and I'm missing something important:

I cannot find the methods which suppose to make my life easier, what are the methods which invoke PUT/POST and DELETE?
I'm using FixtureAdapter, I want to make sure the methods for add/delete and edit, that I'm writing now, will be functional with the RESTAdapter when my server side will be completed.
