ruby on rails - Routing for model that has an association from another module -

i'm trying figure out problem i'm having generating paths, , need put in routes file.

at moment have following:

class car   has_many :doors, class_name: 'cars::door' end  module cars   class door   end end

when attempting render simple form door, i.e

simple_form [@car, @car.doors.build]

i following error

undefined method 'car_cars_doors_path'

the above pseudo code, forgive typos. can tell me need put in routes.rb fix this?

since car model scoped under module cars, don't have scope again car object in simple form

simple_form_for @car.doors.build

this generate path cars_doors_path. if need car_doors_path, have specify explicitly

simple_for_for @car.doors.build, :url => car_doors_path
