ruby-on-rails – 设计自定义路由无法找到路径的映射？

我正在尝试设置自定义的facebook身份验证路径,并且我一直都会遇到这个无用的设计错误.它提到我需要为路线设置我的devise_scope,正如你所看到的,我做到了！我无法弄清楚还有什么办法可以让这个错误发挥作用.

MyApp::Application.routes.draw do

root :to => 'high_voltage/pages#show',id: 'index'

namespace :api,defaults: {format: :json} do
  namespace :v1 do
    # i've removed all the extra routes for other resources. 
    # I do not have one for users set up

    devise_for :users
    devise_scope :user do
      post '/users/facebook',to: 'sessions#facebook'
    end

    get 'users/:id/events',to: 'users#events'

  end
end
end

我的帖子

myapp[development*] $curl -H 'Content-Type: application/json' -d '{"auth_token": "12345"}' http://localhost:3000/api/v1/users/facebook

和错误

AbstractController::ActionNotFound at /api/v1/users/facebook
============================================================

> Could not find devise mapping for path "/api/v1/users/facebook".
This may happen for two reasons:

1) You forgot to wrap your route inside the scope block. For example:

  devise_scope :user do
    get "/some/route" => "some_devise_controller"
  end

2) You are testing a Devise controller bypassing the router.
   If so,you can explicitly tell Devise which mapping to use:

   @request.env["devise.mapping"] = Devise.mappings[:user]



devise (3.1.1) app/controllers/devise_controller.rb,line 84
------------------------------------------------------------

``` ruby
   79       @navigational_formats ||= Devise.navigational_formats.select { |format| Mime::EXTENSION_LOOKUP[format.to_s] }
   80     end
   81
   82     def unknown_action!(msg)
   83       logger.debug "[Devise] #{msg}" if logger
>  84       raise AbstractController::ActionNotFound,msg
   85     end
   86
   87     # Sets the resource creating an instance variable
   88     def resource=(new_resource)
   89       instance_variable_set(:"@#{resource_name}",new_resource)

和控制器

class Api::V1::SessionsController < Devise::SessionsController
  respond_to :json
  before_filter :authenticate_user!,:except => [:create,:destroy]
  skip_before_action :verify_authenticity_token

  def facebook
  end
end

最后我的路线..

api_v1_users_facebook POST   /api/v1/users/facebook(.:format)        api/v1/sessions#facebook {:format=>:json}

这个错误没有任何意义,因为我已经准确地说明了他们想要的方式,我已经尝试了各种其他解决方案,但是没有工作.

谢谢！

devise_for :users,:path_prefix => 'api/v1'
