I just installed foundation in a rails 4 app. Foundation overrwites the layout file.
It replaces:
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
to just:
<%= stylesheet_link_tag "application" %>
is there some sort of incompatibility or should I append back the turbolinks tracking directive?
There is no incompatibility. I've used Turbolinks with Foundation without any issues on several projects.
At any rate, I wouldn't think Foundation would affect Turbolinks, as it's just an HTML/CSS/jQuery framework. From what I understand, Turbolinks works by preloading data from links on a page so if you click one, the page loads quicker.
