Hello,
I''m just starting out with RoR and have been playing around with making
my own blog using RoR as a quick way of getting my feet wet. RoR is neat
isn''t it! Liking the link_to etc helpers, seems such a good way of
doing
things.
Anyway, my little problem goes like this:
I want a link that says Comments (#of comments), for instance "Comments
(2)".
To make my link without the number, I have used:
<%= link_to ''Comments'', {:action =>
''show'', :id => post, :anchor =>
''comments''}, :class => ''comments'' %>
And I know that:
<%= post.comments.count %>
tells me how many comments are for this post. (I''m looping through a
load, so the :id exists etc.)
How do I do this?
<%= link_to ''Comments (post.comments.count)'', {:action
=> ''show'', :id =>
post, :anchor => ''comments''}, :class =>
''comments'' %>
so that the code actually executes? I can''t work it out!
Thanks!

You can also just use +, alhtough #{} is generally cleaner. ''Comments '' + post.comments.count.to_s -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
