my tests seem to imply that << forces an insert of the parent and child
records in a has_many relationship when both are newly created objects.
Class XY < ActiveRecord....
where XY has a "has_many" association with PC and PC has a "belongs_to"
I note that two INSERTs are performed into the tables behind PC and XY
models as a result of the call to addPC() but I'm not issuing a .save
anywhere in my code.
Is this normal behaviour?
