has_one_accessor ========== A simple plugin to allow you to use an ActiveRecord HasOne Association's attributes like those of your own model. It will give you nice setter and getter methods that will dynamically build the association, set it, and save it only on save of the underlying record. This is useful for taking input from forms; User.new(params[:user]) is much nicer than auth_params = params[:user].delete(:auth) user = User.new(params[:user]) user.authentication || user.build_authentication user.authentication.openid_url = auth_params[:openid_url] ...blah blah blah... Simplicity and peace of mind is but a `has_one_accessor` away Example ======= class User has_one :authentication has_one_accessor :authentication, [:openid_url, :facebook_token], :allow_blank => false end this gives us user.authentication_openid_url user.authentication_openid_url= user.authentication_facebook_token user.authentication_facebook_token= and with :allow_blank => false, it'll remove records with blank values on save. also, if you prefer to generate methods without a :prefix has_one_accessor :authentication, :google_id, :prefix => false will give us user.google_id user.google_id= with all of the same niceties Copyright (c) 2008 [Matthew Rudy Jacobs], released under the MIT license
