An attempt for a render_relative for rails

ApplicationHelper.rb

# e.g. inside app/views/records/show.html.erb use
#
# <%= render_relative "./record/title" %>
#
# to render app/views/records/show/record/title

module App::ApplicationHelper
  def render_relative(relative_partial_path, locals = {}, &block)
    calling_file_directory = @virtual_path.split("/")[0..-2].join("/")
    partial_path = File.join(calling_file_directory, relative_partial_path)
    render(partial_path, locals, &block)
  end
end
