Creating a profile with after_create

I have a User and a Profile model, and want to use the last one for
storing some settings and preferences. I think i have the
relationships right (User...has_one :profile,
Profile...belongs_to :user) and a user_id field in the profile_table

What i would like to do is automatically create a profile after
someone registers, using...
after_create :create_profile
...in the User model and in the same file...

def create_profile
  profile.create!
end

this doesn't work, and self.profile.create...etc neither. What am i
doing wrong here? Doesn't profile (in profile.create!) refer to the-
created-user.profile?

Here's how this is handled in one of my current applications:

class User < ActiveRecord::Base
   has_one :preference, :dependent => :destroy
   after_create :initialize_preference

   protected

   # after create filter
   def initialize_preference
     (self.preference = Preference.default).save
   end

end

class Preference < ActiveRecord::Base
   belongs_to :user

   def self.default
     new(DEFAULTS)
   end
end

And the Preference::DEFAULTS is just a hash of attribute values. Preference.default is also used for anonymous users on the system. If you substitute "Profile" for "Preference", I think you'll get the behavior that you're looking for.

thanks, this seems to be working

def create_profile
  (self.profile = Profile.new).save!
end

although i have the feeling this could be written in a cleaner way...?
