Adding custom data attributes rails image tag

Question

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:

Answer 1

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.

Answer 2

The correct syntax for this is

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