example code for filepicker.io rails drag and drop? -

i'm using filepicker rails gem here:

https://github.com/filepicker/filepicker-rails

i'd convert existing rails upload form use filepicker.io rails gem. existing form uses rails, bootstrap, , datamapper , looks this:

<%= form_for([@user, @photo],   html: {multipart: true, remote: true, class: 'photo-upload'} ) |f| %>   <%= f.hidden_field :user_id, value: @user.id %>   <div class="select-files">     <div class="field">       <%= f.label :image, "select files computer" %>       <%= f.file_field :image, multiple: true %>     </div>   </div>   <div class="actions">     <%= f.submit "upload", class: "btn btn-large btn-primary" %>   </div> <% end %> 

my conversion looks this:

<%= form_for([@user, @photo]) |f| %>   <div>     <%= f.label :image, "select files computer:" %>     <%= f.filepicker_field :image %>    </div>   <%= f.submit %> <% end %>
