Rails - May 2006 - Initializing aggregated structures

I have a model, Vendor, which belongs_to :account, :visiting_address.
(1..1 for both)

Now, to ''prevent redundancy''/inconsistencies, the Vendor model
doesn''t
have a name attribute, but instead stores it''s name in account.name.
(Should probably be the other way around, but that''s messier)

My controller goes something like this:

@vendor = Vendor.new(:name => whatever)

While vendor has the following methods:

  def initialize(*args)  # param look reasonable, btw? seems to be
working atm, but..
    super
    self.account ||= Account.new
    self.visiting_address ||= Address.new
  end

  def name=(name)
    self.account ||= Account.new
    account.name = name
  end

Not the best way to go around this, I''m sure...? Suggestions?
