Updating model with has_one association - do not want to update associated model

rubyonrails-talk

I have two classes: Article and Update. When I try to update an Article, it is NOT saving the instance, but is only saving the associated Update object (which is valid).

class Article < ActiveRecord::Base   has_one :update, :as => :content, :dependent => :destroy end

class Update < ActiveRecord::Base   belongs_to :content, :polymorphic => true, :readonly => true end

class ArticlesController < ApplicationController   def update     @article = Article.find(params[:id])

    if @article.update_attributes(params[:article])       flash[:notice] = 'Article was successfully updated.'       redirect_to(@article)     else       render :action => 'edit'     end   end end

When I check my log; however, you can see that only the Update object was updated, not the Article object. Any thoughts on why? I haven't done much with Rails 2.2, but this is not the behavior I remember from earlier versions.

Thanks, Josh
