Filters

Rails
#1

Hi,

How I do a filter in a block of code?

example:

I have a block:

<% @notes[(0…3)].each do |note| %>


  • <%= notes.note %>
    <%= notes.type %>

    • <% end %>

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

    Thanks!

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

    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.
