I'll be watching for your help, thanks.
You can use to_sym method on hash or string so in your code you can do something like this:
instead this:
<%= raw @page.content_for(Refinery::Pages.default_parts.first.to_sym) if Refinery::Pages.default_parts.any? %>
put this:
<%= raw @page.content_for(Refinery::Pages.default_parts.first[:title].to_sym) if Refinery::Pages.default_parts.any? %>
instead [:title]you can also use [:slug]
