I meant "references", either directly or indirectly by means of some
standard class like "Array of non-AR models".
Looks like a good rule of thumb would be: if all child models are
referenced by means of AR''s DSL like has_many, has_one, etc. then
only the root model needs to be passed to model(). Otherwise pass as
many models as needed recursively (sounds very fragile). In any case,
putting a model that would be loaded anyway does not hurt.
Does that look right?
