ruby-on-rails – 设计自定义路由无法找到路径的映射？

概述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 doroot :to => 'high_voltage/pages#show', id: 'index'name 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 doroot :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'  endendend

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"  end2) 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)```App backtrace-------------Full backtrace-------------- -

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  endend

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！

解决方法 我使用RocketPants遇到了类似的问题,但我认为它是等效的.我解决了使用：path_prefix =>在我的情况下’1′,在你的情况下,我会尝试使用：

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

请查看此文档https://github.com/plataformatec/devise#configuring-routes

我没有在命名空间中嵌入devise_for
