check Cookies are disabled or not in ruby on rails

I m developing web application using Ruby on Rails. I want to check whether cookies are enabled or not. If not then i m displaying an error message and user cant proceed further.

In application_controller i did this..

before_filter :cookies_required
def cookies_required
    return true unless cookies["_no_app"].blank?        
    render :template => "shared/cookies_required", :layout => "login"
end

And the code in shared/cookies_required.html.erb is...

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<%= stylesheet_link_tag "login.css"%>
<head>
    <style type="text/css">
        body { background-color: #fff; color: #666; text-align: center; font-family: arial, sans-serif; }
        div.dialog {
            width: 25em;
            padding: 0 4em;
            margin: 4em auto 0 auto;
            }
        h1 { font-size: 100%; color: #f00; line-height: 1.5em; }
    </style>
</head>
<body>

<div class="dialog">
<p><font size="4">Cookies are disabled. First enable it.</font> </p>
</div>
</body>
</html>

This code is working fynn... but problem is when the browser first loaded the page, displays error msg tht cookies are disabled, even if it is enabled...

Change your method to the following:

def cookies_required
   return true unless request.cookies.blank?  
   render :template => "shared/cookies_required", :layout => "login"
end
