Adding custom data attributes rails image tag

I need to add data-description and data-title for galleria in my rails application but I can't see how to do this with the image tag. So far I have this: 

<div id="galleria">
<% @entries.each do |entry| %>
     <%= image_tag entry.filename, :title => "title", :class => "class", :data-description => entry.caption, :data-title => entry.caption  %>
 <% end %>
 </div>

But this raises the undefined local variable or method `description' error, so how would I do this in rails 3?

As of rails 5.1, this syntax should work:

<%= image_tag entry.filename, title: "title", class: "class", data: {description: entry.caption, title: entry.caption} %>

Read more about attributes you can include in your image_tag under examples: rails api docs.

The correct syntax for this is

<%= image_tag entry.filename, :title => "title", :class => "class", :data => { :description => entry.caption, :title => entry.caption }  %>
