rails 3路由堆栈级别设计太深

Question

我收到有关我的路线文件的错误

SystemStackError (stack level too deep):
  actionpack (3.2.8) lib/action_dispatch/middleware/reloader.rb:70


  Rendered /Users/duy/.rvm/gems/ruby-1.9.3-p194/gems/actionpack-3.2.8/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.5ms)
  Rendered /Users/duy/.rvm/gems/ruby-1.9.3-p194/gems/actionpack-3.2.8/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (1.3ms)

我可以隔离有问题的代码,但不明白是什么创建了无限循环:

  devise_for :users, :controllers => { :registrations => "registrations", :sessions => "sessions", :omniauth_callbacks => "users/omniauth_callbacks" }
  devise_scope :user do
    match '/sessions/simulate_user/:id' => 'sessions#simulate_user', :as => :simulate_user_sessions
    match '/sessions/leave_simulation_mode' => 'sessions#leave_simulation_mode', :as => :leave_simulation_mode_sessions
    get "user_confirmation", :to => "devise/confirmations#create"
    get "after_confirmation", :to => "challenges#index"
  end

任何帮助将不胜感激!

编辑:

class SessionsController < Devise::SessionsController

  def new

    @after_sign_in_page = params[:after_sign_in_page] if params[:after_sign_in_page]
    super
  end

  def create
    params[:user][:email].downcase!
    super
  end

  def simulate_user
    if can? :simulate_user, User
      admin = current_user.id
      sign_out
      @user = User.find(params[:id])
      if sign_in @user
        session[:simulation_for] = admin
        redirect_to request.referer
      else
        flash[:notice] = "Something went wrong"
        redirect_to action: "leave_simulation_mode"
      end
    end
  end

  def leave_simulation_mode
    @user = User.find(session[:simulation_for])
    sign_out
    if sign_in @user
      session[:simulation_for] = nil
    else
      flash[:notice] = "something went wrong..."
    end
    redirect_to request.referer
  end

end
class ChallengesController < ApplicationController
      def index
        params[:format] = "html" unless params[:subaction].nil?
        @video = true unless user_signed_in?
        if current_user
          @current_page = params[:page] ? params[:page].to_i : 1
          @columns = params[:cols] ? params[:cols] : 2
          @keyword = params[:keyword]
          @search = true if params[:search] == "1"
          @challenges = Challenge.is_open.where(id: current_user.challenges.filtered(params[:keyword],params[:user],params[:expertize]).collect(&:root_id).uniq)
          logger.debug "Challenges found: #{@challenges.count}"
          @users = User.scoped
          @expertizes = Expertize.all
        end

        respond_to do |format|
          format.html {
            if current_user
              if current_user.challenges.waiting_for_approval.count == 1 and @challenges.count == 1
                redirect_to challenge_path(current_user.challenges.waiting_for_approval.first, subaction: "description")
                return
                logger.debug "REdirect called"
              else
                @challenges = @challenges.page(1).per(@current_page.to_i * 10).order('children_count+tasks_count desc')
              end
            end
            render
            }
          format.json { render json: @challenges }
          format.js {
            @challenges = @challenges.page(@current_page).per(10).order('children_count+tasks_count desc')
            render
          }
        end
      end
end

另外,我忘了提到当我重新启动本地服务器时,它工作正常.每次我更改routes.rb文件,我都会收到此错误.然后我必须重新启动瘦服务器,然后我可以继续...

我和你有同样的问题.这必定是一些宝石造成的问题.

就像我用"devise_invitable"和"devise"一样.然后每次我在开发环境中修改路由文件.它会从"lib/action_dispatch/middleware/reloader.rb"引发"堆栈太深"的错误.

看完你的帖子.我试着评论devise_for:users.重新加载路线是好的.

然后我尝试从Gemfile中删除"devise_invitable".

经过改动.它不会引起错误.这是在我使用Rails 3.2.9之后发生的.我有另一个项目<Rails 3.2.9,两个宝石的工作正确.
