I have a table invitations that have a user_id pointing to the person

I would definitely forget the conventions and make the columns
something like invited_by_id and invited_id. Then in your model:
belongs_to :invited_by, :class_name => "User", :foreign_key =>
belongs_to :invited, :class_name => "User", :foreign_key =>
"invited_id" was invited by
