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. 

3. **\<%= column.human\_name %\>:** \<%=h @noticia.send(column.name)  
%\>
4. 

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/](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/](http://localhost:3000/home/rss/)’ +  
noticia.id.to\_s)
