I have 3 models

sites, user_favorites and users. Relevant relationships:

class Site < ActiveRecord::Base
  has_many :users, :through => :user_favorites

class UserFavorite < ActiveRecord::Base
  belongs_to :user, :counter_cache => true
  belongs_to :site
end

class User < ActiveRecord:Base
  has_many :user_favorites
  has_many :sites, :through => :user_favorites

All of that works just fine. I'd like to add a new attribute to the Site model to indicate which user created it.

I don't believe this constitutes a has_and_belongs_to_many scenario. A site has many users through user_favorites but I want it to belong to a single user reflecting the owner/creator.

I'm wondering what the ORM best practice is for this. SQL wise I'd just use different joins depending on what I was trying to query with a created_by FK in Site. Sorry if I'm missing something basic here.

Thanks
