:with_disabled attribute

I'm newbie to RoR, can anybody explain what is the purpose of
":with_disabled => true" in

belongs_to :person, :class_name => 'Party', :foreign_key => 'person_id',
:with_disabled => true

Because I'm getting the following error

Unknown key(s): with_disabled

FYI: I couldnt find any documenttion for it.

I don’t think that exists at all as an option on belongs_to. What makes you think it should exist? The only similarly named thing is submit_tag which takes a :disable_with option if my memory is correct
