Rails - Apr 2006 - Custom built link_to display text problem

Hi,

I want to display the number of comments for a post in a link_to.  So 
the link will look like below.

Comments(3)

How do i build this string in the link_to.  I get an error about trying 
to convert a fixnum to a string see code below.

<% case post.comments.size
     when 0 %>
        <p>No Comments</p>
    <% else %>
        <P><%= link_to ''Comments('' +
post.comments.size + '')'', :action
=> ''show'', :id => post %></P>
    <% end %>

On another note.  Would it be better to seperate this code into a 
controller returning a string saying No Comments/Comments(x) incase i 
needed it in more than 1 place?

How about this:

<P><%= link_to (post.comments.size>
0)?"Comments(#{post.comments.size})":''No comments'',
:action => ''show'',
:id => post %></P>
