iZauth

iZauth is an implementation of tech task for iZettle company. This is a very basic system that allows users to register, sign in and see their five latest login details.

The working instance can be seen here (not guaranteed to be there forever)

Requirements

iZauth relies on Ruby on Rails framework and the following gems:

• Devise: configurable authentication system
• Bootstrap: popular CSS framework
• HAML: templating engine
• SQLite3: simple database engine that stores the files locally (any other DB engine could be used)

Installation

Installation is simple. First step is to checkout the repo:

git clone git@github.com:gipnokote/izauth.git

Then the dependencies have to be installed:

bundle install

SQLite gem might require to install some libs which may vary depending on the server system.

Finally, the database has to be created:

rake db:create
rake db:migrate

Usage

iZauth Devise gem was configured to have the very basic authentication process. It doesn't send the confirmation emails. For registration user needs only to enter any email (dummy one suits fine) and a password. Devise is very flexible and when a need comes it can be tweaked to deliver all the advanced features.

Implementation of login logging

Devise has such features as tracking user's last and current login time and IP, but it cannot store five last logins, so the Login model was generated for this purpose. Devise's Sessions and Registrations controllers were overriden in iZauth code, to run callbacks after signing up and logging in. User model has been given an update_logins method which creates a new Login record using Devise's current_sign_in_ip and current_sign_in_at info, and deletes all records except the first five.
