title: Princely is generation text/html instead application/pdf?
body: <p>I'm using Princely and Rails 3. 
  When I try to render a pdf like this..
  <code>
  respond_to do |format|<br>
      format.pdf do<br>
              render :pdf => "filename", :template => "path/template.pdf"<br>
        end<br>
      end<br>
  </code></p>
  
  <p>The downloaded file is a text/html format.</p>
  
  <p>How can I fix this and make it work. I have already added the line bellow to config/initializers/mime_types.rb<br></p>
  
  <p>Mime::Type.register "application/pdf", :pdf</p>
