Can't display flash notice

I am unable to display notice variable in my template. Code is below:

class UserController < ApplicationController
  protect_from_forgery
  skip_before_filter :require_login, :except=>[:list,:add,:delete,:update]
  def add
  end

  def delete
  end

  def update
  end

  def list
  end

  def login
  end

  def logout
  end

  def isloggedin
    login = params[:login].to_s
    password = params[:password].to_s
    logged_in = User.where(:user_name => login,:password => password).limit(1)
    if not logged_in.blank?
      session[:userinfo] = logged_in
      redirect_to '/event/list'
    else

      flash[:notice] = 'Unable to login'
      redirect_to '/user/login'
    end

  end
end

Template file

<div><%= notice %></div>

It was because I was getting error Can't verify CSRF token authenticity. I added following input field in form and it started showing message:

<input name="authenticity_token" type="hidden" value="<%= form_authenticity_token %>" />

Add this into your template file:

<% flash.each do |key, value| %>
   <div class="alert alert-<%= key %>"><%= value %></div>
<% end %>

So when your run your code next time key is replace with "notice" and value with "unable to login"

Hope this help! Thanks
