Hey all, I''m trying to get a link_to to display a link to the number of comments for a post. I can get the number + text with pluralize post.comments.count, ''Comment'' but I can''t seem to do <%= link_to pluralize post.comments.count, ''Comment'', :action => ''show'', :id => post, :anchor => ''comments'' %> What would be the best way to do this? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This is what you are after:
<% link_text = "#{post.comments.count} #{pluralize(post.comments.count,
''Comment'')}" -%>
<%= link_to link_text, :action => ''show'', :id =>
post, :anchor =>
''comments'' %>
If you nest function calls, you need to parenthesize the inner calls.

You just need to put the arguments to pluralize in parentheses (see my other post).
