How to render a partial in sinatra view (haml in haml)?

Question

I have a simple sinatra app that uses haml and sass for the views. One of the views (located in the views folder) is a partial for my navigation menu. I am trying to render it from index.haml but I get the following error: wrong number of arguments (1 for 2)

I am trying to render it with the following lines in index.haml

.navigation
  = render :partial => "nav"

Answer 1

You can just use Sinatra's haml function:

= haml :nav

Answer 2

Or you could just do this:

helpers do
  def partial(page, options={})
    haml page.to_sym, options.merge!(:layout => false)
  end
end

And include your partial with:

= partial( "something-rad" )
