WCAI Data Management Webapp

This application is designed to manage files stored on S3 and databases stored on EC2 instances. Timesheet management is also a component of this application.

Application Roles

There are four roles associated with users of this application. Each role has abilities defined in app/models/abilities.rb. Here is where we specify what components of the site a given user is allowed to interact with. Cancan controls access behind the scenes by preloading and checking if a user is able to access a given record. For someone new to cancan this might be confusing. Notice in the controller class we have removed many of the standard definitions. These are all handled by cancan.
