README

Once installed you can do stuff like this:

// Adding permissions to a user
$user->givePermissionTo('edit articles');

// Adding permissions via a role
$user->assignRole('writer');

$role->givePermissionTo('edit articles');

Because all permissions will be registered on Laravel's gate, you can test if a user has a permission with Laravel's default can function:

$user->can('edit articles');

Installation

You can install the package via composer:

composer require moahada/laravel-mongodb-permission

You can publish the migration with:

php artisan vendor:publish --provider="Moahada\Permission\PermissionServiceProvider" --tag="migrations"

php artisan migrate

You can publish the config file with:

php artisan vendor:publish --provider="Moahada\Permission\PermissionServiceProvider" --tag="config"

When published, the config/permission.php config file contains:

return [

    'models' => [

Usage

First, add the Moahada\Permission\Traits\HasRoles trait to your User model(s):

use Illuminate\Auth\Authenticatable;
use Jenssegers\Mongodb\Eloquent\Model as Model;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Moahada\Permission\Traits\HasRoles;

class User extends Model implements AuthenticatableContract, AuthorizableContract
{
    use Authenticatable, Authorizable, HasRoles;

    // ...
}

Note: that if you need to use HasRoles trait with another model ex.Page you will also need to add protected $guard_name = 'web'; as well to that model or you would get an error

use Jenssegers\Mongodb\Eloquent\Model as Model;
use Moahada\Permission\Traits\HasRoles;

class Page extends Model
{
    use HasRoles;

    protected $guard_name = 'web'; // or whatever guard you want to use

    // ...
}

This package allows for users to be associated with permissions and roles. Every role is associated with multiple permissions. A Role and a Permission are regular Moloquent models. They require a name and can be created like this:

use Moahada\Permission\Models\Role;
use Moahada\Permission\Models\Permission;

$role = Role::create(['name' => 'writer']);
$permission = Permission::create(['name' => 'edit articles']);

A permission can be assigned to a role using 1 of these methods:

$role->givePermissionTo($permission);
$permission->assignRole($role);

Multiple permissions can be synced to a role using 1 of these methods:

$role->syncPermissions($permissions);
$permission->syncRoles($roles);

A permission can be removed from a role using 1 of these methods:

$role->revokePermissionTo($permission);
$permission->removeRole($role);

If you're using multiple guards the guard_name attribute needs to be set as well. Read about it in the using multiple guards section of the readme.

The HasRoles trait adds Moloquent relationships to your models, which can be accessed directly or used as a base query:

// get a list of all permissions directly assigned to the user
$permissions = $user->permissions; // Returns a collection

// get all permissions inherited by the user via roles
$permissions = $user->getAllPermissions(); // Returns a collection

// get all permissions names
$permissions = $user->getPermissionNames(); // Returns a collection

// get a collection of all defined roles
$roles = $user->roles->pluck('name'); // Returns a collection

// get all role names
$roles = $user->getRoleNames() // Returns a collection;

The HasRoles trait also adds a role scope to your models to scope the query to certain roles or permissions:

$users = User::role('writer')->get(); // Returns only users with the role 'writer'
$users = User::permission('edit articles')->get(); // Returns only users with the permission 'edit articles'

The scope can accept a string, a \Moahada\Permission\Models\Role object, a \Moahada\Permission\Models\Permission object or an \Illuminate\Support\Collection object.

Using "direct" permissions

A permission can be given to any user with the HasRoles trait:

$user->givePermissionTo('edit articles');

// You can also give multiple permission at once
$user->givePermissionTo('edit articles', 'delete articles');

// You may also pass an array
$user->givePermissionTo(['edit articles', 'delete articles']);

A permission can be revoked from a user:

$user->revokePermissionTo('edit articles');

Or revoke & add new permissions in one go:

$user->syncPermissions(['edit articles', 'delete articles']);

You can test if a user has a permission:

$user->hasPermissionTo('edit articles');

...or if a user has multiple permissions:

$user->hasAnyPermission(['edit articles', 'publish articles', 'unpublish articles']);

Saved permissions will be registered with the Illuminate\Auth\Access\Gate class for the default guard. So you can test if a user has a permission with Laravel's default can function:

$user->can('edit articles');

Using permissions via roles

A role can be assigned to any user:

$user->assignRole('writer');

// You can also assign multiple roles at once
$user->assignRole('writer', 'admin');
// or as an array
$user->assignRole(['writer', 'admin']);

A role can be removed from a user:

$user->removeRole('writer');

Roles can also be synced:

// All current roles will be removed from the user and replaced by the array given
$user->syncRoles(['writer', 'admin']);

You can determine if a user has a certain role:

$user->hasRole('writer');

You can also determine if a user has any of a given list of roles:

$user->hasAnyRole(Role::all());

You can also determine if a user has all of a given list of roles:

$user->hasAllRoles(Role::all());

The assignRole, hasRole, hasAnyRole, hasAllRoles and removeRole functions can accept a string, a \Moahada\Permission\Models\Role object or an \Illuminate\Support\Collection object.

A permission can be given to a role:

$role->givePermissionTo('edit articles');

You can determine if a role has a certain permission:

$role->hasPermissionTo('edit articles');

A permission can be revoked from a role:

$role->revokePermissionTo('edit articles');

The givePermissionTo and revokePermissionTo functions can accept a string or a Moahada\Permission\Models\Permission object.

Permissions are inherited from roles automatically. Additionally, individual permissions can be assigned to the user too.

For instance:

$role = Role::findByName('writer');
$role->givePermissionTo('edit articles');

$user->assignRole('writer');

$user->givePermissionTo('delete articles');

In the above example, a role is given permission to edit articles and this role is assigned to a user. Now the user can edit articles and additionally delete articles. The permission of delete articles is the user's direct permission because it is assigned directly to them. When we call $user->hasDirectPermission('delete articles') it returns true, but false for $user->hasDirectPermission('edit articles').

This method is useful if one builds a form for setting permissions for roles and users in an application and wants to restrict or change inherited permissions of roles of the user, i.e. allowing to change only direct permissions of the user.

You can list all of these permissions:

// Direct permissions
$user->getDirectPermissions() // Or $user->permissions;

// Permissions inherited from the user's roles
$user->getPermissionsViaRoles();

// All permissions which apply on the user (inherited and direct)
$user->getAllPermissions();

All these responses are collections of Moahada\Permission\Models\Permission objects.

If we follow the previous example, the first response will be a collection with the delete article permission, the second will be a collection with the edit article permission and the third will contain both.

Using Blade directives

This package also adds Blade directives to verify whether the currently logged in user has all or any of a given list of roles.

Optionally you can pass in the guard that the check will be performed on as a second argument.

Blade and Roles

Test for a specific role:

@role('writer')
    I am a writer!
@else
    I am not a writer...
@endrole

is the same as

@hasrole('writer')
    I am a writer!
@else
    I am not a writer...
@endhasrole

Test for any role in a list:

@hasanyrole(Role::all())
    I have one or more of these roles!
@else
    I have none of these roles...
@endhasanyrole
// or
@hasanyrole('writer|admin')
    I am either a writer or an admin or both!
@else
    I have none of these roles...
@endhasanyrole

Test for all roles:

@hasallroles(Role::all())
    I have all of these roles!
@else
    I do not have all of these roles...
@endhasallroles
// or
@hasallroles('writer|admin')
    I am both a writer and an admin!
@else
    I do not have all of these roles...
@endhasallroles

Blade and Permissions

This package doesn't add any permission-specific Blade directives. Instead, use Laravel's native @can directive to check if a user has a certain permission.

@can('edit articles')
  //
@endcan

@if(auth()->user()->can('edit articles') && $some_other_condition)
  //
@endif

Using artisan commands

You can create a role or permission from a console with artisan commands.

php artisan permission:create-role writer

php artisan permission:create-permission 'edit articles'

When creating permissions and roles for specific guards you can specify the guard names as a second argument:

php artisan permission:create-role writer web

php artisan permission:create-permission 'edit articles' web

moahada / laravel-mongodb-permission
