Top 3 Style

You just need to track which row you're on. If you use render :partial then you automatically get an index variable (if the partial is foo then you get foo_counter)

Hi,

I'm using a bog standard .find(:all) in my controller which the <% for
%> loop in my view then displays the results of.

How can I apply a different css style (class or id) to the first
result
that my view returns? and then subsequently the 2nd and 3rd (basically
Gold, Silver, Bronze). All the rest just use a generic style.

You could use a hash with a default value and index it with the position:

medal_class = Hash.new('generic').update(1=>'Gold', 2=>'Silver',

3=>'Bronze')
=> {1=>"Gold", 2=>"Silver", 3=>"Bronze"}

medal_class[1]

=> "Gold"

medal_class[2]

=> "Silver"

medal_class[3]

=> "Bronze"

medal_class[4]

=> "generic"

medal_class[5]

=> "generic"

medal_class[0]

=> "generic"

If you follow Fred's advice and use a partial for a row, then the *_counter will be a good choice. If you have a simple loop with .each_with_index {|thing,index| ... }, then you'd have to adjust 0=>'Gold', etc. to match the zero-based array index.

Personally, I hate <% for %> and prefer to go with the underlying <%
each %>... and for your purpose you might also consider using <%
each_with_index %>. Combine that with Rob's suggestion and you can
use the index from the loop to index the medal_class hash.
