同一rails资源的多个devise_for路由

Question

我正在使用Rails 3和Devise的现有Web应用程序.我目前的任务是向应用程序添加JSON API.我创建了一个Mobile :: SessionsController(<Devise :: SessionsController),它使用仅数据响应实现'#create'.

问题出在路由中.现在,routes.rb的相关部分如下:

 # For the web app:
  devise_for :users, :controllers => {:sessions => 'sessions',
                                      :registrations => 'registrations'}
  as :user do
    get "/login" => "devise/sessions#new"
    get "/logout" => "devise/sessions#destroy", :as => :logout
    post '/signup' => 'registrations#signup', :as => :signup
  end
  # And for the API, later on:
  namespace :api do
    namespace :user do
      devise_for :users, :controllers => {:sessions => 'mobile/sessions'},
                 skip: :all
      devise_scope :user do
        post 'login' => 'mobile/sessions#create'
      end
...

数据端点位于/ api/user/login.rake routes列出以下内容:

api_user_login POST /api/user/login(.:format) api/user/mobile/sessions#create

在我的规范中,有以下内容:

describe Mobile::SessionsController do
  render_views
  describe '#create' do
    context 'for some condition' do
      let(:params) do
        {
          # basic params
        }
      end
      before do
        post :create, params.merge(format: :json)
      end

      it 'should render a json response' do
        expect(response.headers['Content-Type']).to eq 'application/json; charset=utf-8'
      end
...

当我运行规范时,它会给出以下错误:

AbstractController::ActionNotFound: Could not find devise mapping for path "/mobile/sessions/create.json?params=blah.
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]

我在第二个devise_for块中尝试了许多不同的配置(模块,无论是否使用skip :: all,完全删除第二个devise_for,将它放在命名空间的不同级别)我无法摆脱这个错误.我的猜测是那里的第二个选项(devise.mapping位)不是解决方案,因为它似乎根本不应绕过路由器.而且由于我的路线恰好是第一种选择所暗示的那种方式,我对于如何解决这个问题感到困惑.我怎么能让这个东西工作？

感谢帮助!

你写了两个 devise_for 这是不正确的。你不需要 api devise_for 因为在 pais 中不需要它
