Atom Feeds, Rails 3.1

Hey everyone,   I've got a strange (or so I think) error with my Atom feed for my company's blog system. I've only started implementing it today and I can't seem to find too much documentation on it unfortunately.\ This issue I have is that I get:

undefined method `post_url' for #<#<Class:0x0000000a7277c0>:0x0000000a6ffae0>, and it finds the extracted source to be from line 5 of feed.atom.builder ( feed.entry post do |entry| , also shown below )

### Blog Controller def feed     @posts = Post.order('id desc').limit(10)     respond_to do |format|       format.atom     end end

### feed.atom.builder atom_feed :language => 'en-US' do |feed|   feed.title "CoverHound.com Blog"   feed.updated @posts.order('id desc').first.created_at   @posts.each do |post|     feed.entry post do |entry|       entry.title post.title       entry.url blog_post_url(:title => post.url_title)       entry.summary post.abstract, :type => 'html'       entry.author post.author.name     end   end end

### routes ... match '/blog/feed' => 'blog#feed', :as => :blog_feed, :defaults => { :format => 'atom' } ...

The strange thing about this error is that I don't specify post_url anywhere in the builder... Somehow, it automatically wants to use that route helper. However, my routes are setup like blog_post_url and not just post_url.

Anyone have any ideas?

Thanks!! - Jeff

Well, I actually figured this one out. Looking at the source, the AtomFeedHelper was grabbing the URL automatically from the record, which is wrong, since it's not stored anywhere in the record itself and the namespace is slightly different than rails conventions (blog_post_url instead of post_url). I was able to pass the URL parameter into the troublesome statement and it works now:

What was: feed.entry post do |entry|

Is now: feed.entry(post, :url => blog_post_url(:title => post.url_title)) do

entry>

Resolved! Thanks, - Jeff
