erb code not executing inside the div tag

Hi Guys

Trying to make the helper method working with Rails 4.1.0 and Ruby 2, so far adding anything in the class="<%= method name %>" does not get executed. any thoughts?

<% flash.each do |key, value| %>
  <div class="<%= flash_class(key) %>">
    <%= value %>
  </div>
<% end %>

Looks like the problem is with the application_helper.rb, for some reason the application.html.erb doesn't have access to it. The code inside application_helper.rb is not running at all! any ideas?

hmm any helper methods inside the application helper should automatically be available in your layout file. are you sure your method is correct? mind posting the method implementation?

Hi stone,

Thanks for your reply. Here is the method:

module ApplicationHelper
  def flash_class(level)
    case level
    when :notice then "alert alert-info"
    when :success then "alert alert-success"
    when :error then "alert alert-error"
    when :alert then "alert alert-error"
    end
  end
end

Any other ideas on why this is not working from within the application_helper only? Thanks
