RSS

[Adriana Sucena]

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 loadâ€.
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)
20. end
21. end
22. end
23. end
