[Rails] Filters

Hi, 

How I do a filter in a block of code?

example:

I have a block:

<% @notes[(0..3)].each do |note| %>

          <li>

            <%= notes.note %>

            <%= notes.type %>

          </li>

<% end %>

Type is a string, I would like to do a block filtering by a value on type.

Thanks!
