ruby-on-rails - 设计自定义路由找不到路径映射？

Question

我正在尝试设置自定义 facebook 身份验证路径，但我一直收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，如您所见，我愿意！我不知道还能做什么才能让这个错误起作用。

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

   81
   82     def unknown_action!(msg)
   83       logger.debug "[Devise] #{msg}" if logger

   85     end

   87     # Sets the resource creating an instance variable

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

最后是我的路线..

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样子，而且我已经从在线解决方案中尝试了各种其他的东西，但都没有奏效。

谢谢！

Answer 1

我在使用 RocketPants 时遇到了类似的问题，但我认为它是等价的。在我的情况下，我使用 :path_prefix => '1' 解决了，在你的情况下，我会尝试使用：

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

检查此文档https://github.com/plataformatec/devise#configuring-routes

我没有devise_for在命名空间中嵌套

Answer 2

我的控制器的资源名称是 api_v1_user 并且应该是用户。我的解决方案是覆盖 resource_name 方法，例如：

class Api::V1::SessionsController < Devise::SessionsController

[...]

  protected

  def resource_name
   :user
  end

end

cf https://github.com/plataformatec/devise/issues/3663#issuecomment-169130536

Answer 3

通过将devise_for语句移到命名空间嵌套之外，我能够克服这个错误：

Rails.application.routes.draw do

  devise_for :users, skip: :all  # Use skip: :all if you don't want all the default devise routes created

  namespace :api do
    scope module: :v1
      devise_scope :user do
        post "/sessions" => "sessions#create"
        delete "/sessions" => "sessions#destroy"
      end
    end
  end
