The interpolated Ruby in a Haml :javascript filter now gets HTML escaped, breaking the way it was being used in the shared _head template to pass the set of valid languages and projects. The fix is to pass it as an HTML dataset instead, and pull that into the Javascript afterwards. I followed the example of railsadminteam/rails_admin#2870

Thanks, this was a helpful example to follow for a similar problem in my app! |

Background
Since Haml 4 doesn't escape interpolated Ruby script, the result of
j I18n.t("admin.js").to_jsonis not HTML-escaped and it's working.Problem
But in Haml 5, such interpolated script is HTML-escaped by default haml/haml#770.
Thus, with Haml 5.0.0.beta.2, it's broken like:
Changes
For security, it'd be good to have it in HTML-escaped form. So, I changed the template to fetch it from data attribute. Using data attribute, we can store JSON object in HTML-escaped form and fetch it safely.
