ruby on rails - belongs_to with multiple models -

I am a rail nuke and have a question. I have a feed aggregator that is organized by this general concept:

Feed category (books, electronics, etc.) Feed site section (home page, book page, etc.) Feed (feed themselves) Entry

Such:

  class category & lt; ActiveRecord :: Base has has_many: feeds have has_many: feed_entries ,: through = & gt; : Feed, limit = & gt; 5 validates_presence_of: name attr_accessible: name ,: id end class section & lt; ActiveRecord :: Base has has_many: feeds have has_many: feed_entries ,: through = & gt; : Feed, limit = & gt; 5 attr_accessible: name ,: id end class feed & lt; ActiveRecord :: base is_to: categories belong_to: class is_many: feed_entries validates_presence_of: name ,: feed_url attr_accessible: name ,: feed_url ,: category_id ,: section_id end class FeedEntry & lt; ActiveRecord :: Base is_to: feed is_to: range belongs_to: section validates_presence_of: title ,: url end  

understand? Now, in my index page, I basically say ... If you are in category books then on the Home page section, give me the feed-class feed entries ...

In my Controller:

  def index = part = section.find_bie_name ("home page") @ books = category.find_b_name ("books") end  

see me in :

  & lt;% = render: partial = & gt; 'Feed_list',: local = & gt; {: Feed_group = & gt; @ Books.feeds} -%>  

This will spit the markup for each feed entry in the @Books collection of partial feeds. Now what do I need to do to combine anyway with @books section ...

I tried to do this:

But this section is not limited by ID. I have confirmed section ID using the same code in the console ...

What do you mean? any advice?

Thank you!

Try something like this:

: Local = & Gt; {: Feed_group = & gt; @ Books.feeds.all (: conditions => {: section_id = & gt; section.id})}
