ruby on rails - Why is my catch-all route not working for some routes? -

i have in routes.rb:

resources :emergencies, except: [:new, :edit, :destroy], defaults: { format: :json } match '*path', to: 'application#page_not_found', via: :all 

i have in application.rb:

config.exceptions_app = self.routes 

and application_controller.rb looks this:

class applicationcontroller < actioncontroller::base   def page_not_found     render json: { message: 'page not found' }, status: :not_found   end end 

i have set of test suites tests :new, :edit, , :destroy route. routes :edit , :destroy pass, returning message page not found expected, :new route returns null. infact, /emergencies/anything render null, /emergences/new/new work correctly. idea on why happening , how can fix route /emergencies/new hitting page_not_found action?

run rake routes see how routes lay out.

you notice show route matches emergencies/:id (this includes emergencies/new, example).

routes match top down. normally, resources declare new route before show route, catch match future declarations.

if can, add constraint show route, if not match id, @ least not match new. or keep resource routes , kick them page_not_found method in before_filter in controller...
