Authorization for Eloquent Models

Authoritaire is an attempt to create a simple, orthogonal authorization library. The premise came after seeing many Laravel 4 user libraries that couple too tightly with projects and attempt to do too much.

Authoritaire facilitates role-based and permissions-per-role authorization checks. Many systems can get by using only roles, however if you need more fine-grained control over things, permissions are available.

Usage

Using Authoritaire is as simple as running the migration:

./artisan migrate --package="atrauzzi/authoritaire"

Implement the interface Authorizable and then add the trait AuthorizableImpl to any model you wish to perform permission checks on.

use Atrauzzi\Authoritaire\Model\Authorizable;
use Atrauzzi\Authoritaire\Model\AuthorizableImpl;

class User implements UserInterface, RemindableInterface, Authorizable {
  use AuthorizableImpl;

  // ...

You can create new Permissions by instantiating them and relating them to a Role.

$eatPlants = Atrauzzi\Authoritaire\Model\Permission::create([
  'name' => 'Eat Plants'
]);

$vegetarian = Atrauzzi\Authoritaire\Model\Role::create([
  'name' => 'Vegetarian',
  'description' => 'Does not eat meat.'
]);
$vegetarian->permissions()->save($eatPlants);

You can grant authorizables membership to Roles from either side using addRole() from Authorizable or addAuthorizable() from Role:

$a = User::first();
$r = Atrauzzi\Authoritaire\Model\Role::where('name', '=', 'Vegetarian')->first();

// Add from authorizable-side.
$a->addRole($r);
// Or add from role-side.
$r->addAuthorizable($a);

Performing checks is as simple as asking the user if they are either a member of a role or have access to a permission. Authoritaire will take care of everything.

$u->is('Vegetarian');                       // true
$u->can('Eat Plants');                      // true
$u->is('Administrator');                    // false

// You can also perform checks for a set of permissions or roles.
$u->is(['Administrator', 'Vegetarian']);    // false

Currently

This version of Authoritaire makes use of some workarounds due to limitations in Laravel 4's polymorphic relations. As such, one join table has to be more directly manipulated than I would have liked.

A big thank you to Todd Francis for his original work on Verify-L4! While I didn't keep the lion's share of his work, it has mostly inspired the schema.
