I'm trying to use princely gem to render diploma pdf for users who have finished courses to route users/:id/serve_diploma.
when I write this route, I see the browser get data and not errors, but I get a blank page.
These are my controller, css and html.erb files:

@user_courses_title_array = Course.find(completed_courses_id_array).map(&:title)
@courses_count = Course.all.count
@completion_date = @user.user_courses.order('completed_course_date DESC').first.completed_course_date
render :pdf => "#{@user.name}",
