Sentinel

Sentinel brings a simple and light-weight role-based permissions system to Laravel's built in Auth system.

Sentinel brings support for the following ACL structure:

• Every user can have zero or more roles.
• Every role can have zero or more permissions.

Permissions are then inherited to the user through the user's assigned roles.

Quick Installation

Begin by installing the package through Composer. The best way to do this is through your terminal via Composer itself:

composer require pierresilva/laravel-sentinel

Once this operation is complete, simply add the service provider to your project's config/app.php file and run the provided migrations against your database.

Service Provider

pierresilva\Sentinel\SentinelServiceProvider::class,

Facade

'Sentinel' => pierresilva\Sentinel\Facades\Sentinel::class,

Then open the Kernel.php file in app\Http\Kernel.php and add this to user it as middleware :

routeMiddleware

 'roles' => \pierresilva\Sentinel\Middleware\UserHasRole::class,
 'permissions' => \pierresilva\Sentinel\Middleware\UserHasPermission::class,

Migrations

You'll need to run the provided migrations against your database. Publish the migration files using the vendor:publish Artisan command and run migrate:

php artisan vendor:publish

php artisan migrate

Usage

Sentinel package comes bundled with a SentinelTrait file to be used within your User's Model file. This trait file provides all the necessary functions to tie your users in with roles and permissions.

Example User Model

<?php

namespace App;

use pierresilva\Sentinel\Traits\SentinelTrait;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use Notifiable;
    use SentinelTrait;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'gender', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

SentinelTrait

The following methods will become available from your User model.

• isRole($roleSlug)
• can($permission)
• assignRole($roleId)
• revokeRole($roleId)
• revokeAllRoles()
• syncRoles([$roleIds])

isRole($roleSlug)

Checks if the user is under the given role.

Auth::user()->isRole('administrator');

You may also use magic methods:

Auth::user()->isAdministrator();

can($permission)

Checks if the user has the given permission(s). You may pass either a string or an array of permissions to check for. In the case of an array, ALL permissions must be accountable for in order for this to return true.

Auth::user()->can('access.admin');

or

Auth::user()->can(['access.admin', 'view.users']);

assignRole($roleId)

Assign the given role to the user.

Auth::user()->assignRole(1);
revokeRole($roleId)

Revokes the given role from the user.

Auth::user()->revokeRole(1);

revokeAllRoles()

Revokes all roles from the user.

Auth::user()->revokeAllRoles();

syncRoles([$roleIds])

Syncs the given roles with the user. This will revoke any roles not supplied.

Auth::user()->syncRoles([1, 2, 3]);

Role Permissions

The bundled Role model has easy to use methods to manage and assign permissions.

• can($permission)
• getPermissions()
• assignPermission($permissionId)
• revokePermission($permissionId)
• revokeAllPermissions()
• syncPermissions([$permissionIds])

can($permission)

Checks if the role has the given permission(s). You may pass either a string or an array of permissions to check for. In the case of an array, ALL permissions must be accounted for in order for this to return true.

$role = Role::find(1);
return $role->can('access.admin');

getPermissions()

Retrieves an array of assigned permission slugs for the role.

$role = Role::find(1);
return $role->getPermissions();

assignPermission($permissionId)

Assigns the given permission to the role.

$role = Role::find(1);
$role->assignPermission(1);
$role->save();

revokePermission($permissionId)

Revokes the given permission from the role.

$role = Role::find(1);
$role->revokePermission(1);
$role->save();

revokeAllPermissions()

Revokes all permissions from the role.

$role = Role::find(1);
$role->revokeAllPermissions();
$role->save();

syncPermissions([$permissionIds])

Syncs the given permissions with the role. This will revoke any permissions not supplied.

$role = Role::find(1);
$role->syncPermissions([1, 2, 3]);
$role->save();
