    text
    copied!<p>I'm trying to use the <a href="http://github.com/rails/atom_feed_helper/tree/master" rel="nofollow noreferrer">Rails Atom Feed Helper</a> to generate a feed for a nested resource. My view template (index.atom.builder) is:</p> <pre><code>atom_feed(:schema_date =&gt; @favourites.first.created_at) do |feed| feed.title("Favourites for #{@user.login}") feed.updated(@favourites.first.created_at) @favourites.each do |favourite| feed.entry(favourite, :url =&gt; favourite.asset.external_ref) do |entry| entry.title(favourite.asset.external_ref) entry.content(image_tag(favourite.asset.location), :type =&gt; 'html') entry.author do |author| author.name(@user.login) end end end end </code></pre> <p>And I have the following routes:</p> <pre><code> map.namespace :public do |pub| pub.resources :users, :has_many =&gt; [ :favourites ] pub.resources :favourites pub.resources :assets, :only =&gt; [ :show ] end </code></pre> <p>Unfortunately the url is failing to generate for the feed.entry line:</p> <pre><code>feed.entry(favourite, :url =&gt; favourite.asset.external_ref) do |entry| </code></pre> <p>The error is "undefined method `favourite_url' for ActionView::Base".</p> <p>I've tried changing the feed.entry line to: </p> <pre><code>feed.entry([:public, favourite], :url =&gt; favourite.asset.external_ref) do |entry| </code></pre> <p>But this then returns the entry for an Array rather than a favourite! Someone had a similar problem <a href="https://rails.lighthouseapp.com/projects/8994/tickets/1093-atom-feed-helper-generates-wrong-ids" rel="nofollow noreferrer">here also</a>.</p> <p>I know that adding the line:</p> <pre><code>map.resource :favourites </code></pre> <p>to my routes.rb would 'fix' this problem but this resource is only available nested beneath the /public namespace.</p> <p>Has anyone had this problem before?</p> <p>Cheers Arfon</p>
