Rails - Jan 2006 - help with link_to_if, I can''t make it work...

For the life of me I can''t get it to work.  Here is an example of my 
syntax.  I''m trying to make comment.name a link to comment.web_site
only
if there is a comment.web_site.  Can someone please help?

<%= link_to_if(comment.web_site.length > 0, comment.name, 
comment.web_site {"class"  => "comment_by"})  %>

Well, it seems like you''ve forgotten a comma.

Try:

<%= link_to_if(comment.web_site.length > 0, comment.name,
               comment.web_site ----->,<------ {"class"  => 
"comment_by"})  %>
