Rails - Nov 2009 - Delegates and building associations

Class User << ActiveRecord::Base
  has_one :profile
  delgate  :description, :description=, :to => :profile

end


I''d like to do,

@user = User.create(:name => ''Foo Bar'', :description =>
''Slow.'')
or
@user = User.update_attributes(:description => ''Slow'')

and have AR create/update the profile model and association (if it
doesn''t already exist).


How can I do this?  Ideally this would be handled in User''s
initialize, or callback, but I can''t get anything to work.  When
reaching the delegate statement I get an error that profile is nil.

Thanks

Write Something like this in your user model
before_create :build_profile_for_this_user

def build_proile_for_this_user
    build_profile
  end
