Hello everyone,
In today’s tutorial I`ll teach you how to create a very basic Login System in Ruby on Rails. Welcome to Tutorial : Create a login system in Ruby on Rails. Before proceeding I would suggest you guys to read Tutorial : Create a blog using Ruby on Rails 2. (Part 1 – Relationships) since we will be using this sytem in our application.

Introduction

We will create a very simple standalone login system first, It will check the database for valid users. Then I`ll let you know how to integrate a similar login system in our blog application. First of course the basics.

We would need to design

• Login page
• A page which would have to be protected by the login system
• Function to Check session, if not valid, then redirect to login page.
