title: Rails create a form in haml file
body: <p>I am sorry if this is a bad question, however I am new to HAML.
  I have a file movies/show.html.haml and I have to create a form for Comment for a movie in it.</p>
  
  <p>In a typical html.erb file I would this:</p>
  
  <pre><code>&lt;%= form_for([@movie, @movie.comments.new]) do |f| %&gt;
    &lt;%= f.text_area :text, class: "form-control" %&gt;
    &lt;%= f.submit, class: "btn btn-primary"
  &lt;% end %&gt;
  </code></pre>
  
  <p>How can I accomplish this in .haml file?</p>
