  end
%>

Hi Jamal,

You need to use link_to like this:
<%= link_to "test", "http://www.rubyonrails.org/" %>

instead of what you are doing:
<% link_to "test", "http://www.rubyonrails.org/" %>

In your example you could do the following:
<%
  if @categories
    for category in @categories %>
      <%= link_to "test", "http://www.rubyonrails.org/"
%>
    <% end
  end
%>

or

<%
  if @categories
    for category in @categories
      puts link_to "test", "http://www.rubyonrails.org/"
    end
  end
%>


HTH,

Mischa

I would like to use the "puts" => but it doesn''t output
anything? The =
is working good but I don''t like to open and close %> all the time
if I
need to use <%

You''re right "puts" doesn''t work.

One suggestion -- to make it look more clean -- is that you make sure in 
the controller that @categories is not nil (instead of in the view). If 
you do that the code in your view could look like this:

<% for category in @categories -%>
  <%= link_to "test", "http://www.rubyonrails.org/" %>
<% end -%>

Cheers,
Mischa
