title: Carrierwave multiple file upload limited
body: <p>For my application, users can upload 6 files in a form.
  So I use this example for this, with "fields_for" : <a href="http://lucapette.com/rails/multiple-files-upload-with-carrierwave-and-nested_form/" rel="nofollow">http://lucapette.com/rails/multiple-files-upload-with-carrierwave-and-nested_form/</a>  </p>
  
  <p>Problem, it is infinite. Is it possible to disable the "Add" button after 6 times or is there any solution for it ? It is not a problem if the 6 fields are present but I don't know how to do this with Rails...</p>
  
  <p>Thanks.</p>
