Thanks, but I think that I figured it out In parent AR,
attr_accessible :addresses_attributes has_many :addresses ### Pretty sure should be plural for has_many, and singular for has_one accepts_nested_attributes_for :addresses Then in the view I have (abbreviated) form @parent_object do |parent_form| ### In the controller I just pass @parent_object = Parent_object.new (AR takes care of all the associations) ... the address sections parent_form.fields_for :addresses do |primary| primary.text_field :address_line_1 primary.hidden_field :address_type_id, :value => 'primary' .... end parent_form.fields_for :addresses do |alternative| alternative.text_field :address_line_1 alternative.hidden_field :address_type_id, :value => 'alternative' .... end I think this may work. Haven't looked at the params yet... -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
