after_sign_in_path_for(资源) 设计 + facebook omniauth

Question

我的用户模型有生日，如果在使用 Facebook 登录后它是空白的，我正在尝试重定向到编辑页面。我尝试覆盖资源的 after_sign_in_path 但不断收到此错误：

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".

我的应用程序控制器：

class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  def after_sign_in_path_for(resource)
    stored_location_for(resource) ||
    if resource.birthday.blank?
      redirect_to edit_user_path(resource)
    end
    super
  end
end

和我的 Omniauth 控制器：

class OmniauthCallbacksController < ApplicationController
  skip_before_filter :authenticate_user!

  def provides_callback_for
    user = User.from_omniauth(env["omniauth.auth"], current_user)
    if user.persisted?
      flash[:notice] = "You have signed in!"
    sign_in_and_redirect(user)
    else
      session['devise.user_attributed'] = user.attributes
      redirect_to new_user_registration_url
    end
  end

  def failure
    flash[:notice] = "Something went wrong!"
    redirect_to root_path
  end

  alias_method :facebook, :provides_callback_for
end

这应该可以解决问题：

def after_sign_in_path_for(resource)
    if resource.birthday.blank?
      edit_user_registration_url
    else
      super
    end
end
