this is because your display_products returns category.productos which is an Array (sort of)

This is the last statement in your method. The each loop is basically spinning it’s wheels.

ret = “

  • ” # Makes a new string at the beginning of each loop

    …

    ret << “

    • ”

    At the end of the block you have a string. But you don’t do anything with it.

    Perhaps if you collected the results of each loop in an array and then joined them. eg

    def display_products(category)

    category.productos.map do |p|

    ret = "<li>"

    ret << link_to_remote( "<span>#{p.nombre}</span>",

                    :url=>{:action

    => “prod_id”, :id => p.id},

                        :update

    => ‘info’)

        ret << "</li>"

end.join

    end

    This would return the finished string at the end of the method.

    There has to be a cleaner way though. Like just appending to the view buffer directly.

    Hope this helps
