ユーザーによってリダイレクトしたいrole_ids：

  • 2 に等しい場合は、にリダイレクトしworkers_pathます。
  • 1 の場合は、にリダイレクトしtasksadmins_pathます。

次のことを定義しました。

class ApplicationController < ActionController::Base
  include ApplicationHelper

  protect_from_forgery
  before_filter :authenticate_user!

  def stored_location_for(user)
    nil
  end

  def after_sign_in_path_for(user)
     if current_user.role_ids == [2]
       return redirect_to(workers_path)
     else
       return redirect_to (tasksadmins_path)
     end
  end
end

しかし、サインインするとエラーが発生しました：

AbstractController::DoubleRenderError in UserSessionsController#create

Render and/or redirect were called multiple times in this action. Please note 
that you may only call render OR redirect, and at most once per action. Also 
note that neither redirect nor render terminate execution of the action, so 
if you want to exit an action after redirecting, you need to do something 
like "redirect_to(...) and return".

これは私のuser_session_controller.rbです：

class UserSessionsController < Devise::SessionsController
  include ApplicationHelper

  def create
      response = super

      require "uri"
      require "net/http"

      ## get the user id from the database
      user_id = session['warden.user.user.key'][1][0];

      ## get the row by id
      user = User.find(user_id)

      # ============================
      # Ensure that a user exists
      # ============================

      code, body = http_request(Net::HTTP::Put.new("/api/v1/users/external/#{user_id}"), email: user.email);
      if code != 200
         Rails.logger.error("Unable to register user #{current_user.email} at Licensario");
      end

      response
   end
end

これは私のものroutes.rbです：

TODOLIST::Application.routes.draw do

    devise_for :users, :controllers => { :sessions => 'user_sessions'} do
        get '/users/sign_out' => 'devise/sessions#destroy'
    end

    resources :tasksadmins
    resources :workers
    root to: "workers#index"
end

redirect_toに戻ってはいけませんafter_sign_in_path_for。次の URL を返す必要があります。

  def after_sign_in_path_for(user)
     if current_user.role_ids == [2]
       return workers_url
     else
       return tasksadmins_url
     end
  end

次の行を「作成」するために追加しました。

最初に、私は書きました：

resource = warden.authenticate!(:scope => resource_name)

そして、「作成」機能の最後に次のように書きました。

sign_in(resource_name, resource)

if current_user.role_ids == [2]
   respond_with resource, :location => workers_path
else
   respond_with resource, :location => tasksadmins_path
end

だから私の作成はそう見える：

class UserSessionsController < Devise::SessionsController
    include ApplicationHelper

    def create

        resource = warden.authenticate!(:scope => resource_name)

        require "uri"
        require "net/http"

        ## get the user id from the database
        user_id = session['warden.user.user.key'][1][0];

        ## get the row by id
        user = User.find(user_id)

        # ============================
        # Ensure that a user exists
        # ============================

        code, body = http_request(Net::HTTP::Put.new("/api/v1/users/external/#{user_id}"), email: user.email);
        if code != 200
           Rails.logger.error("Unable to register user #{current_user.email} at Licensario");
        end

        sign_in(resource_name, resource)

        if current_user.role_ids == [2]
           respond_with resource, :location => workers_path
       else
           respond_with resource, :location => tasksadmins_path
       end

    end
end
