DataAttributes

A gem to provide HTML data attributes easily from model to view.

Just add this into your Gemfile:

gem 'data_attributes'

If you want to take benefits of content_tag_for and div_for methods, add also record_tag_helper into your Gemfile:

gem 'record_tag_helper'

Then, just run a bundle install.

In your model just add DataAttributes::Model mixin:

class Article

  include DataAttributes::Model

end

Then, you can define you model's data attributes that are included into view:

class Article

  include DataAttributes::Model

  data_attribute :id, :title

end

Note that DataAttributes::Model mixin is automatically added into ActiveRecord::Base (if present).

Then content_tag_for and div_for methods from record_tag_helper gem will add model's data attributes into view:

<%= div_for @article do %>
<!-- <div class="article" data-id="42" data-title="Hello!"> -->

You can also pass data attributes directly to content_tag method:

<%= content_tag :div, id: 'articles', data: { count: 28 } do %>

This project is fully tested with Rspec 3. Just run bundle exec rake (after a bundle install).
