def current = recognize(@template.request)

#dashboard_href ⇒ Object

Path to the opt-in dashboard overview, or nil until a host writes the dashboard template (app/views/cafe_car/dashboard/show.html.haml) — its existence is the opt-in. The dashboard route lives in the engine (not the host's routes), so it's resolved through the engine's own url helpers — that works from any host controller regardless of where CafeCar is mounted.
