命名空间嵌套资源

Question

我的项目上有以下路线：

namespace :teacher do
 resources job_applications do
   resources :job_application_addresses
 end

我的表单有以下代码

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

我的控制器具有以下内容：

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

最后我收到此错误：

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| %>

这是我对此视图的路线：

teacher_job_application_job_application_addresses GET    /teacher/job_applications/:job_application_id/job_application_addresses(.:format)          teacher/job_application_addresses#index
                                                              POST   /teacher/job_applications/:job_application_id/job_application_addresses(.:format)          teacher/job_application_addresses#create
          new_teacher_job_application_job_application_address GET    /teacher/job_applications/:job_application_id/job_application_addresses/new(.:format)      teacher/job_application_addresses#new
         edit_teacher_job_application_job_application_address GET    /teacher/job_applications/:job_application_id/job_application_addresses/:id/edit(.:format) teacher/job_application_addresses#edit
              teacher_job_application_job_application_address GET    /teacher/job_applications/:job_application_id/job_application_addresses/:id(.:format)      teacher/job_application_addresses#show
                                                              PATCH  /teacher/job_applications/:job_application_id/job_application_addresses/:id(.:format)      teacher/job_application_addresses#update
                                                              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

我该怎么办？我会感谢你的帮助。

Answer 1

您的job_application_addresses是job_application的嵌套资源。但我在你的形式上看不到它。您可以通过两种方式做到这一点：

1. 您可以在simple_form_for url 构建器中添加job_application对象，如下所示

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

2. 您可以在表单中添加网址选项

   <%= simple_form_for [@job_application, @job_application_address], url: teacher_job_application_job_application_addresses_path do |form|
   <% end %>`
   

在这两种情况下，您都需要在控制器中new操作中具有@job_application object。

希望对你有帮助
