/ We allow cross-module references in the UI but not in the controller hence:
- unit = Renalware::Hospitals::Unit.find(unit_id)
- breadcrumbs = [breadcrumb_for("Hospital Units", hospitals_units_path),
                 breadcrumb_for(unit.unit_code, edit_hospitals_unit_path(unit)),
                 breadcrumb_for("Stations", hd_unit_stations_path(unit))]

= within_admin_layout(title: "Edit", breadcrumbs: breadcrumbs) do
  = render "form", station: station, url: hd_unit_station_path(station.hospital_unit_id, station)
