don't know about DataMapper. In activerecord as soon as you call find
you'll get a normal record/array of records. if you just want
something that adds some extra conditions then you may be interested
in named_scope. The other thing is that (in active record) scopes
scope a particular table, so when you do Shop.find(1).categories then
the categories proxy there is scoping finds on Category to those with
the appropriate shop_id - it's not magic thing across everything with
a shop_id column.
