Вложенные ресурсы пространства имен

У меня есть следующие маршруты в моем проекте:

namespace :teacher do
 resources job_applications do
   resources :job_application_addresses
 end

Моя форма имеет следующий код

<%= simple_form_for [:teacher, @job_application_address] do |form|

<% end %>

И мой контроллер имеет следующее:

def new
 @job_application_address = JobApplicationAddress.new
end

def create
 @job_application_address = JobApplicationAddress.new(job_application_address_params)
 @job_application_address.job_application = @job_application
   if @job_application_address.save
    flash[:success] = 'Successfully created'
   end
end

Наконец я получаю эту ошибку:

undefined method `teacher_job_application_addresses_path' for #<#<Class:0x00007fda0c4191d0>:0x00007fda143d1af8>
Did you mean?  teacher_job_application_path
               teacher_job_applications_path

Extracted source (around line #3):
<%= simple_form_for [:teacher, @job_application_address] do |form| %>

Это мои маршруты для этого представления:

                                                              PUT    /teacher/job_applications/:job_application_id/job_application_addresses/:id(.:format)      teacher/job_application_addresses#update
                                                              DELETE /teacher/job_applications/:job_application_id/job_application_addresses/:id(.:format)      teacher/job_application_addresses#destroy

Что я должен делать? Я буду признателен за вашу помощь.
