is this route possible? - ruby-on-rails

Question

hi im new in ruby on rails development and currently im working in a reservation system i made a semi static page with a controller inside it has a functionroom action
my functionroom action is
def functionroom
#reservation = Reservation.find(params[:reservation_id])
#function_room = FunctionRoom.all
end
but when i try to route to functionroom coming from the reservation module with this route
<%= link_to "add functionrooms", reservation_pages_functionroom_path(#reservation) %>
it gives me a uninitialized constant Reservations error
im just wondering if im working with my routes right dealing with the pages/functionroom static page.
resources :reservations do
resources :reservation_function_rooms
resources :reservation_packages
get 'pages/functionroom'
resources :package_line_items
end
error stack:

Answer 1

You can make route of it like in this way also
resources :reservations do
resources :pages do
collection do
get :functionroom
end
end
resources :reservation_function_rooms
resources :reservation_packages
resources :package_line_items
end
but you can check routes through rake routes
it will sure work........

Answer 2

run 'rake routes' to check your path

Answer 3

Check your controller name if it "reservations_controller.rb" or "reservation_controller"?
if it "reservation_controller.rb" then change it to "reservations_controller.rb"
code
class ReservationsController < ApplicationController
end
