Hi,

I'm trying to do RSS in my page, using ruby. Something is appearing in
the browser, but I'm with some problems:
1 - If I'm not logged in, nothing appears in the bookmark.
2 - If I'm logged in, when I put another new in my data base, this one
doesn't appear in the bookmark
3 - After closing the browser and close it again, the bookmark says
“Live Bookmark feed failed to load”.
To solve the first problem, I must change my "noticias_controller"... I
must clear the line
   before_filter :authorize, :except => [:show]
but I think I'm using nothing more besides "show" from this controller.

Could you please tell me what is missing in my code?

File rss.rhtml
   1. <% for column in Noticia.content_columns %>
   2. <p>
   3.   <b><%= column.human_name %>:</b> <%=h @noticia.send(column.name)
%>
   4. </p>
   5. <% end %>


File feedxml.rhtml
   1. xml.instruct! :xml, :version=>"1.0"
   2.
   3. xml.rss('version' => '2.0') do
   4.     xml.channel do
   5.         xml.title('GEMCC News')
   6.         xml.link ('http://localhost:3000/home')
   7.         xml.description('Description.')
   8.         xml.language('en-us')
   9.         xml.pubDate('Sun, 9 Dez 2006 04:00:00 GMT')
  10.         xml.lastBuildDate('Sun, 9 Dez 2006 04:00:00 GMT')
  11.
  12.         for noticia in @noticia
  13.             xml.item do
  14.                 xml.title(noticia.title)
  15.                 @noticia = Noticia.find(noticia.id)
  16.                 xml.description(@noticia.title + " - " +
@noticia.news)
  17.                 xml.link('http://localhost:3000/home/rss/' +
noticia.id.to_s)
  18.                 xml.pubDate('Sun, 9 Dez 2006 04:00:00 GMT')
  19.                 xml.guid('http://localhost:3000/home/rss/' +
noticia.id.to_s)
