title: How to use view helpers with rails-api gem?
body: <p>I use <a href="https://github.com/spastorino/rails-api">rails-api</a> and <a href="https://github.com/nesquena/rabl">rabl</a> gems to make api application. I don't want to put a lot of logic into rabl views but if that I want to extract it into helpers. Rails-api gem doesn't include helpers support (and thats ok) so <strong>how I can enable helpers into my json views?(what middleware I need to include, which modules etc)</strong></p>
