Camping list - Oct 2011 - which view am I inside?

How can I guess the view''s name in my layout method?

It would be great to know because of highlight the current
menu item the user has selected.  Of course I can store it in
a variable in my controller just before I call render :view, but I
hope there''s a much more sexy way to do this.

If you''re using Markaby (that is, templates written in Ruby under
MyApp::Views) and Ruby 1.9 you can use __method__:

module App::Views
  def foo
    p "I''m inside: #{__method__}"
  end
end

But you can''t use that in a layout or partial though (it would just
return "layout" or the name of the partial)?

My question was about the layout.  Suppose that Alfa and Beta are
menu items in the layout, and I want to mark the current menu item
with different appearance:


module App::Views
  def layout
    case .....  #<--- Which view am I currently rendering?   :alfa or :beta?
      when :alfa
        # generate an alfa-selected menu
      when :beta
        # generate a beta-item-selected menu
    end
    div(:class => :content) {
      self << yield
    }
  end

  def alfa
    "Alfa"
  end

  def beta
    "Beta"
  end
end

You could always override the render-method yourself:

module App::Helpers
  def render(name, *rest)
    @template_name = name.to_s unless name == :layout
    super
  end
end

module App::Views
  def layout
    h1 "I''m in #{@template_name}"
    self << yield
  end
end
