Authegy

The Authegy gem is a library that combines several top-grade ruby libraries to provide an opinionated authentication and role-based authorization solution for your rails apps.

The following libraries are used as the base of Authegy:

  • Devise
  • Doorkeeper

These libraries are used following a particular set of rules:

  • Only a single User class: whereas devise allows for multiple "authenticatable" models, we're going use single class, to which we can assign different roles instead.
  • The "profile" user data - such as names, email, phone, etc. - is extracted into a separate Person model. We actually can create Person records without an associated user, enabling us to manage a "contact list".
  • Roles added to a given person can be assigned either unlimited, or scoped to a given "resource" object.
  • The only way of giving access to an app's RESTAPI (where available) is through an OAuth2 flow (i.e. access token, etc) - that's where Doorkeeper comes into play. Given that our most common use case for RESTAPIs is to be consumed by non-confidential apps (Single-page apps, mobile apps, etc), we're avoiding other solutions such as Devise JWT, Devise Token Auth, etc.
  • All OAuth2 (doorkeeper) apps will have an owner, and admin roles may be given to other people to manage the apps.
  • Restrictions coming from the OAuth2 access token permissions will be added to those already in effect from roles for the token's resource owner.

Getting started

Add this line to your application's Gemfile:

gem 'authegy', '~> 0.0.2'

Then run bundle install.

Next, you'll need to run the generator:

$ rails generate authegy:install

The install generator will run the install routines for the required libraries ( devise, etc), and will also generate the required models, database migration and routes to start working with the authegy model.

Model methods

There are several methods available to the Person and User models, and are very similar to the methods found at other RBAC libraries:

# Create a person:
example_person = Person.create first_name: 'Example', last_name: 'Person', email: 'first@example.com'

# Assign a role to this person - The role will be created if it doesn't exist:
example_person.assign_role :administrator

# Assign a user to this person - he/she will now have the ability to sign-in:
example_user = example_person.create_user! password: '123456'

# You can assign roles scoped to a particular resource:
example_person.assign_role :moderator, Discussion.last

# You can test if the person has a role:
example_person.has_role? :moderator, Discussion.last

# All the role management methods are available to the `User` model via method
# delegation:
example_user.assign_role :moderator, Discussion.first
example_user.has_role? :moderator, Discussion.first

The Authegy model, in detail

Base Use Case

  • We extracted the User fields not fundamental to the process of authentication into the model Person. This allows us to also cover cases in which we are asked to manage a "contact list", with people that either can sign-in or not. Notice the email field is also moved to the Person model - we provide the code required for Devise to look in the people table.
  • The way we assign roles to a person is using the RoleAssignment model. This model also allows us to optionally specify a resource to which the assigned role will be limited (or scoped). Notice how the RoleAssignment is separated from the actual Role model, achieving a higher level of database normalization.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
