Question

I have a sessionsController and I’m trying to add a redirect_back_or method in my sessions_helper to allow friendly forwarding.

Here is the error I get:

undefined method `redirect_back_or' for #<SessionsController:0x007f9fa1b51ec0>

I have restarted the server and can’t figure out why it’s not finding this method in my helper.

My Sessions helper code is as follows:

module SessionsHelper

  def deny_access
      store_location
      redirect_to signin_path, :notice => "Please sign in to access this page."
  end

  def redirect_back_or(default)
      redirect_to(session[:return_to] || default)
      clear_return_to
  end

  private

  def store_location
        session[:return_to] = request.fullpath
  end

  def clear_return_to
    session[:return_to] = nil
  end

end

My sessions controller is

class SessionsController < ApplicationController

  def create
    auth = request.env["omniauth.auth"]
    user = User.find_by_provider_and_uid(auth["provider"], auth["uid"]) || User.create_with_omniauth(auth)
    session[:user_id] = user.id
    redirect_back_or user
    #redirect_to root_url, :notice => "Signed in!"
  end

  def destroy
    session[:user_id] = nil
    redirect_to root_url, :notice => "Signed out!"
  end

end

Put that method in ApplicationController:

class ApplicationController < ActionController::Base
  private
  def redirect_back_or(default)
      redirect_to(session[:return_to] || default)
      clear_return_to
  end
end

Or include the SessionsHelper module in your controller to use the method:

class SessionsController < ApplicationController
  include SessionsHelper
  ...
