= Session Persistence
Rails 3 plugin that lets you set how long you want your session to be persisted/remembered.
session_expires_after 2.weeks
session_expires_automatically # also aliased to expire_session
The timespan will reset on every request. If you set it to 2 weeks, and the user returns after 1 week, the session will be refreshed and last 2 weeks again. If the user returns after 3 weeks, the session will be reset.
A call to session_expires_automatically will return to a normal automatical expiry cookie, that will expire when the browser is closed.
Note: I haven't tested the plugin with memcache session storage, but it should work there as well.
= Usage
Here's an example sessions controller in a Rails 3 application.
class SessionsController < ApplicationController
def create
session_expires_after 2.weeks if params[:remember_me]
# ..normal auth goes here..
# for example
user = User.authenticate(params[:username], params[:password])
if user
session[:user] = user.id
else
# ..
end
end
def destroy
session_expires_automatically
# ..unauthorize here..
# for example
session[:user] = nil
redirect_to root_path
end
end
