Question

How do I add a controller-specific menu (or div) inside a general application layout in Rails?

Answer 1

method 1: set a variable in that controller

class SomeController
  before_filter :set_to_use_menu

  private

  def set_to_use_menu
    @use_menu = true
  end
end

method 2: determine the controller’s name in the layout

<%- if controller_name == "your_controller_name" %>
  <%= render :partial => "the_menu" %>
<%- end %>
