Rails: Passing array values to tag helpers like link_to

From at least Rails 4, the ActionView tag helper turns Array values of HTML options into a single space-separated string.
This means you can pass an array to :class options:

extra_classes = %w[one two] = link_to 'Dashboard', root_path, class: ['btn', 'btn-primary', *extra_classes] => <a href="/" class="btn btn-primary one two">Dashboad</a> = content_tag 'div', 'Hello World', class: %w[alert alert-info] => <div class="alert alert-info">Hello World</div> = content_tag 'span', 'Hello World', class: [] => <span class>Hello World</span>

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
