Alternate row classes with Ruby on Rails

Posted on 23 March 2006

Using the built in TextHelper cycle method makes alternate row classes so easy in Ruby on Rails.

If your table rows are being ouput via a loop then you can use cycle() to automatically use alternate classes for each row...

<%- for item in @items do -%>

  <tr class="<%= cycle("even", "odd") %>">
    ... use item ...
  </tr>

<%- end -%> 

Then in my CSS i'd use something like:

tr.even td{
	background-color:#CCC;
}

tr.odd td{
	background-color:#EEE;
}
