Rails: CSRF token not working but configured

Question

I have a rails 3 application for heroku, and when I send banking information, I get: WARNING: Can't verify CSRF token authenticitybut my CSRF token is configured. https://gist.github.com/anonymous/7081401

$.ajax({ url: '#{credit_cards_path}', 
type: 'POST',
beforeSend: function(xhr) {xhr.setRequestHeader('X-CSRF-Token', '#{form_authenticity_token}')},
dataType: "json",
data: { cc_uri: response.data.uri, 
        address: $('.address').val()
        // etc ...
      },
success: function(randomobject) {
  window.location = '/products/' + randomobject.value + '/receipt';
  }
});

Maybe you should use #{form_authenticity_token}

According to this source WARNING: It is not possible to verify the CSRF token authentication rails , you should be able to use this code:

headers: {
  'X-Transaction': 'POST Example',
  'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
},
