Is it possible to get the name of the currently rendered view from inside layout?

I did something like this for css namespacing:
# config/initializers/action_view.rb
ActionView::TemplateRenderer.class_eval do
def render_template_with_tracking(template, layout_name = nil, locals = {})
# with this gsub, we convert a file path /folder1/folder2/subfolder/filename.html.erb to subfolder-filename
@view.instance_variable_set(:@_rendered_template, template.inspect.gsub(/(\..*)/, '').split('/')[-2..-1].join('-'))
out = render_template_without_tracking(template, layout_name, locals)
@view.instance_variable_set(:@_rendered_template, nil)
return out
end
alias_method_chain :render_template, :tracking
end
# application.html.erb
<body class="<%= :@_rendered_template %>" >
