登录重定向后设计 - 双重渲染错误

Question

我正在使用rails 3.2和Devise(最新版本)

主要想法是在登录后测试当前登录用户的一些变量.因此,例如,如果用户有待创建地址我想重定向新地址路径.但我得到的是双重渲染错误.

这是代码

class ApplicationController < ActionController::Base
  protect_from_forgery

 # Devise: Where to redirect users once they have logged in
  def after_sign_in_path_for(resource)

        if current_user.is? :company_owner
            if $redis.hget(USER_COMPANY_KEY, current_user.id).nil?
                redirect_to new_owner_company_path and return
            else
                @addr_pending = $redis.hget(PENDING_ADDRESS_KEY,current_user.id)
                unless @addr_pending.nil? || !@addr_pending
                     redirect_to owner_company_addresses_path  and return
                end
            end
        end
        root_path
  end
end

我的路线定义

  root :to => "home#index"
    devise_for :users, :controllers => { 
    :omniauth_callbacks => "users/omniauth_callbacks" 
  }
    resources :users, :only => :show

    namespace :owner do
        resource :company  do # single resource /owner/company
            get 'thanks'
            get 'owner' #TODO: esto hay que sacarlo de aquí y forme parte del login
            resources :addresses
        end
    end

所以,当我用一个创建了pedding地址的用户登录时,我得到了

"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".

出什么问题了？

 redirect_to owner_company_addresses_path  and return

所以,我只想重定向到新的地址路径.我不明白为什么我得到错误.

提前致谢.

----编辑----

似乎只返回一个路径(我认为使用redirect_to并返回就足够了,但事实并非如此)

def after_sign_in_path_for(resource)

        @final_url = root_path
        if current_user.is? :company_owner
            if $redis.hget(USER_COMPANY_KEY, current_user.id).nil?
                @final_url = new_owner_company_path
            else
                @addr_pending = $redis.hget(PENDING_ADDRESS_KEY,current_user.id)
                unless @addr_pending.nil? || !@addr_pending
                     @final_url = owner_company_addresses_path
                end
            end
        end
        @final_url
  end

您应该删除redirect_to方法调用和return语句.after_sign_in_path_for应该只返回一条路径:

例如:

def after_sign_in_path_for(resource)
  new_owner_company_path
end
