Rails: в том числе проблема с контроллером приводит к тому, что действие 'index' не может быть найдено

Question

Использование рельсов в качестве API (но ApplicationController

Контроллер записей:

class EntriesController < ApplicationController
    include current_user_concern
    def index
        @entries = Entry.where(user_id: @current_user.id)
        # if(params[:tag])
        #   @entries = @entries.tagged_with(params[:tag])
        # end
        render json: @entries
    end

current_user_concern:

module CurrentUserConcern
  extend ActiveSupport::Concern

  included do
    before_action :set_current_user
  end

  def set_current_user
    puts "in currentUserConcern set_current_user"
    puts session[:user_id]
    if session[:user_id]
      @current_user = User.find(session[:user_id])
    end
  end
end

С текущим кодом Я получаю ошибку AbstractController::ActionNotFound (The action 'index' could not be found for EntriesController):, хотя user_id действительно выводится на консоль bash.

Если я удаляю строку include current_user_concern из records_controller, при выполнении она входит в индекс (но, как и ожидалось, ошибки в @ current_user.id что было бы определено в current_user_concern)

Из журнала консоли bash видно, что, возможно, индекс вызывается перед проблемой?

Answer 1

Должно быть include CurrentUserConcern вместо include current_user_concern

class EntriesController < ApplicationController
  include CurrentUserConcern
end
