Rails - Jun 2011 - 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!

However, your code will be much more testable if you do the filtering
on @notes in the controller, or even better, by writing a method in
your model that only returns records with type of class String.
