Remember Me

In this tutorial we will build upon the app created at Simple Password Authentication so make sure you understand it.

Adding remember me to the app is very simple - just use the good old login method with a third parameter. This is usually the result of a "Remember me" check box from a form. If it's anything that evals to true, it will 'remember' the user.

    # app/controllers/user_sessions_controller.rb
    @user = login(params[:username],params[:password],params[:remember])

To "forget me" just logout.

If you ever need finer control you can use the controller methods:

    remember_me!
    forget_me!

There are options to configure expiration time and more. See the gem docs for a full list.
