Hi I need help in coding for the login page of the application on which i am currently working on. It is an open source project. so you can directly support my team by joining http://www.fedena.com
Have you tried any of the usual authentication plugins? "restful_authentication":http://github.com/technoweenie/restful-authentication/ is a Rails plugin that is widely used, once installed it provides you with a generator that creates the login page as well as the needed code. It's a good place to start but make sure you understand what the generated code is doing for you.
