Ajax device authentication doesn't work? - ruby-on-rails

Question

i tried to use the following tutorial for rails api authentication by using json & ajax: http://jessehowarth.com/devise
it seem to work, but no matter what login-credentials i enter (existing and non-existing), it fails everytime i hit submit.
i make the request using node.js
var post_data = querystring.stringify({
'email' : 'foo#bar.com',
'password': 'foo',
'remember_me': 1
});
var options = {
host: 'localhost',
path: '/users/sign_in.json',
port: '3000',
method: 'POST'
};
callback = function(response) {
var str = '';
response.on('data', function (chunk) {
str += chunk;
});
response.on('end', function () {
console.log(str);
});
}
var req = http.request(options, callback);
req.write(post_data);
req.end();
my devise-session controller looks like this:
class SessionsController < Devise::SessionsController
def create
respond_to do |format|
format.html{ super }
format.json do
resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#failure")
return sign_in_and_redirect(resource_name, resource)
end
end
end
def sign_in_and_redirect(resource_or_scope, resource=nil)
scope = Devise::Mapping.find_scope!(resource_or_scope)
resource ||= resource_or_scope
sign_in(scope, resource) unless warden.user(scope) == resource
respond_to do |format|
format.json {render :json => {:success => true, :redirect => stored_location_for(scope) || after_sign_in_path_for(resource)}}
format.html {redirect_to root_url}
end
end
def failure
respond_to do |format|
format.json { render:json => {:success => false, :errors => ["Login failed."]} }
end
end
end
the output i get:
{"success":false,"errors":["Login failed."]}
any advice on this?
thanks!

Okay, actually it was my fault. but if someone is as silly as me:
I used the parameters email, password and remember_me instead of user[email], user[password] and user[remember_me]…
Solved!
