This package allows you to manage user permissions and roles in a database.

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');

If you're using multiple guards we've got you covered as well. Every guard will have its own set of permissions and roles that can be assigned to the guard's users. Read about it in the using multiple guards section of the readme.

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

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

Laravel

This package can be used in Laravel 5.4 or higher. If you are using an older version of Laravel, take a look at the v1 branch of this package.

You can install the package via composer:

composer require codemastersolucoes/laravel-permission

In Laravel 5.5 the service provider will automatically get registered. In older versions of the framework just add the service provider in config/app.php file:

'providers' => [
    // ...
    CodeMaster\Permission\PermissionServiceProvider::class,
];

You can publish the migration with:

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

If you're using UUIDs or GUIDs for your User models you can update the create_permission_tables.php migration and replace $table->unsignedBigInteger($columnNames['model_morph_key']) with $table->uuid($columnNames['model_morph_key']). For consistency, you can also update the package configuration file to use the model_uuid column name instead of the default model_id column.

After the migration has been published you can create the role- and permission-tables by running the migrations:

php artisan migrate

You can publish the config file with:

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

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

return [

    'models' => [

Lumen

You can install the package via Composer:

composer require codemastersolucoes/laravel-permission

Copy the required files:

mkdir -p config
cp vendor/codemastersolucoes/laravel-permission/config/permission.php config/permission.php
cp vendor/codemastersolucoes/laravel-permission/database/migrations/create_permission_tables.php.stub database/migrations/2018_01_01_000000_create_permission_tables.php

You will also need to create another configuration file at config/auth.php. Get it on the Laravel repository or just run the following command:

curl -Ls https://raw.githubusercontent.com/laravel/lumen-framework/5.7/config/auth.php -o config/auth.php

Then, in bootstrap/app.php, register the middlewares:

$app->routeMiddleware([
    'auth'       => App\Http\Middleware\Authenticate::class,
    'permission' => CodeMaster\Permission\Middlewares\PermissionMiddleware::class,
    'role'       => CodeMaster\Permission\Middlewares\RoleMiddleware::class,
]);

As well as the config file, service provider, and cache alias:

$app->configure('permission');
$app->alias('cache', \Illuminate\Cache\CacheManager::class);  // if you don't have this already
$app->register(CodeMaster\Permission\PermissionServiceProvider::class);

Now, run your migrations:

php artisan migrate

Usage

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

use Illuminate\Foundation\Auth\User as Authenticatable;
use CodeMaster\Permission\Traits\HasRoles;

class User extends Authenticatable
{
    use 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 Illuminate\Database\Eloquent\Model;
use CodeMaster\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 Eloquent models. They require a name and can be created like this:

use CodeMaster\Permission\Models\Role;
use CodeMaster\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 Eloquent 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;

// get all permissions for the user, either directly, or from roles, or from both
$permissions = $user->getDirectPermissions();
$permissions = $user->getPermissionsViaRoles();
$permissions = $user->getAllPermissions();

// get the names of the user's roles
$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'

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

The same trait also adds a scope to only get users that have a certain permission.

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

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

Using "direct" permissions (see below to use both roles and permissions)

A permission can be given to any user:

$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 check if a user has a permission:

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

Or you may pass an integer representing the permission id

$user->hasPermissionTo('1');
$user->hasPermissionTo(Permission::find(1)->id);
$user->hasPermissionTo($somePermission->id);

You can check if a user has Any of an array of permissions:

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

...or if a user has All of an array of permissions:

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

You may also pass integers to lookup by permission id

$user->hasAnyPermission(['edit articles', 1, 5]);

Saved permissions will be registered with the Illuminate\Auth\Access\Gate class for the default guard. So you can check 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 \CodeMaster\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 CodeMaster\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 CodeMaster\Permission\Models\Permission objects.

If we follow the previous example, the first response will be a collection with the delete article permission and 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

Check 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

Check for any role in a list:

@hasanyrole($collectionOfRoles)
    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

Check for all roles:

@hasallroles($collectionOfRoles)
    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

Alternatively, @unlessrole gives the reverse for checking a singular role, like this:

@unlessrole('does not have this role')
    I do not have the role
@else
    I do have the role
@endunlessrole

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

Defining a Super-Admin

We strongly recommend that a Super-Admin be handled by setting a global Gate::before rule which checks for the desired role.

Then you can implement the best-practice of primarily using permission-based controls throughout your app, without always having to check for "is this a super-admin" everywhere.

See this wiki article on Defining a Super-Admin Gate rule in your app.

Best Practices -- roles vs permissions

It is generally best to code your app around permissions only. That way you can always use the native Laravel @can and can() directives everywhere in your app.

Roles can still be used to group permissions for easy assignment, and you can still use the role-based helper methods if truly necessary. But most app-related logic can usually be best controlled using the can methods, which allows Laravel's Gate layer to do all the heavy lifting.

Using multiple guards

When using the default Laravel auth configuration all of the above methods will work out of the box, no extra configuration required.

However, when using multiple guards they will act like namespaces for your permissions and roles. Meaning every guard has its own set of permissions and roles that can be assigned to their user model.

Using permissions and roles with multiple guards

When creating new permissions and roles, if no guard is specified, then the first defined guard in auth.guards config array will be used. When creating permissions and roles for specific guards you'll have to specify their guard_name on the model:

// Create a superadmin role for the admin users
$role = Role::create(['guard_name' => 'admin', 'name' => 'superadmin']);

// Define a `publish articles` permission for the admin users belonging to the admin guard
$permission = Permission::create(['guard_name' => 'admin', 'name' => 'publish articles']);

// Define a *different* `publish articles` permission for the regular users belonging to the web guard
$permission = Permission::create(['guard_name' => 'web', 'name' => 'publish articles']);

To check if a user has permission for a specific guard:

$user->hasPermissionTo('publish articles', 'admin');

Note: When determining whether a role/permission is valid on a given model, it chooses the guard in this order: first the $guard_name property of the model; then the guard in the config (through a provider); then the first-defined guard in the auth.guards config array; then the auth.defaults.guard config.

Note: When using other than the default web guard, you will need to declare which guard_name you wish each model to use by setting the $guard_name property in your model. One per model is simplest.

Note: If your app uses only a single guard, but is not web then change the order of your listed guards in your config/app.php to list your primary guard as the default and as the first in the list of defined guards.

Assigning permissions and roles to guard users

You can use the same methods to assign permissions and roles to users as described above in using permissions via roles. Just make sure the guard_name on the permission or role matches the guard of the user, otherwise a GuardDoesNotMatch exception will be thrown.

Using blade directives with multiple guards

You can use all of the blade directives listed in using blade directives by passing in the guard you wish to use as the second argument to the directive:

@role('super-admin', 'admin')
    I am a super-admin!
@else
    I am not a super-admin...
@endrole

Using a middleware

This package comes with RoleMiddleware, PermissionMiddleware and RoleOrPermissionMiddleware middleware. You can add them inside your app/Http/Kernel.php file.

protected $routeMiddleware = [
    // ...
    'role' => \CodeMaster\Permission\Middlewares\RoleMiddleware::class,
    'permission' => \CodeMaster\Permission\Middlewares\PermissionMiddleware::class,
    'role_or_permission' => \CodeMaster\Permission\Middlewares\RoleOrPermissionMiddleware::class,
];

Then you can protect your routes using middleware rules:

Route::group(['middleware' => ['role:super-admin']], function () {
    //
});

Route::group(['middleware' => ['permission:publish articles']], function () {
    //
});

Route::group(['middleware' => ['role:super-admin','permission:publish articles']], function () {
    //
});

Route::group(['middleware' => ['role_or_permission:super-admin']], function () {
    //
});

Route::group(['middleware' => ['role_or_permission:publish articles']], function () {
    //
});

Alternatively, you can separate multiple roles or permission with a | (pipe) character:

Route::group(['middleware' => ['role:super-admin|writer']], function () {
    //
});

Route::group(['middleware' => ['permission:publish articles|edit articles']], function () {
    //
});

Route::group(['middleware' => ['role_or_permission:super-admin|edit articles']], function () {
    //
});

You can protect your controllers similarly, by setting desired middleware in the constructor:

public function __construct()
{
    $this->middleware(['role:super-admin','permission:publish articles|edit articles']);
}

public function __construct()
{
    $this->middleware(['role_or_permission:super-admin|edit articles']);
}

Catching role and permission failures

If you want to override the default 403 response, you can catch the UnauthorizedException using your app's exception handler:

public function render($request, Exception $exception)
{
    if ($exception instanceof \CodeMaster\Permission\Exceptions\UnauthorizedException) {
        // Code here ...
    }

    return parent::render($request, $exception);
}

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/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

When creating roles you can also create and link permissions at the same time:

php artisan permission:create-role writer web "create articles|edit articles"

Unit Testing

In your application's tests, if you are not seeding roles and permissions as part of your test setUp() then you may run into a chicken/egg situation where roles and permissions aren't registered with the gate (because your tests create them after that gate registration is done). Working around this is simple: In your tests simply add a setUp() instruction to re-register the permissions, like this:

    public function setUp()
    {
        // first include all the normal setUp operations
        parent::setUp();

        // now re-register all the roles and permissions
        $this->app->make(\CodeMaster\Permission\PermissionRegistrar::class)->registerPermissions();
    }

Database Seeding

You may discover that it is best to flush this package's cache before seeding, to avoid cache conflict errors. This can be done directly in a seeder class. Here is a sample seeder, which first clears the cache, creates permissions and then assigns permissions to roles (the order of these steps is intentional):

use Illuminate\Database\Seeder;
use CodeMaster\Permission\Models\Role;
use CodeMaster\Permission\Models\Permission;

class RolesAndPermissionsSeeder extends Seeder
{
    public function run()
    {
        // Reset cached roles and permissions
        app()[\CodeMaster\Permission\PermissionRegistrar::class]->forgetCachedPermissions();

        // create permissions
        Permission::create(['name' => 'edit articles']);
        Permission::create(['name' => 'delete articles']);
        Permission::create(['name' => 'publish articles']);
        Permission::create(['name' => 'unpublish articles']);

        // create roles and assign created permissions

        // this can be done as separate statements
        $role = Role::create(['name' => 'writer']);
        $role->givePermissionTo('edit articles');

        // or may be done by chaining
        $role = Role::create(['name' => 'moderator'])
            ->givePermissionTo(['publish articles', 'unpublish articles']);

        $role = Role::create(['name' => 'super-admin']);
        $role->givePermissionTo(Permission::all());
    }
}

Extending

If you need to EXTEND the existing Role or Permission models note that:

Your Role model needs to extend the CodeMaster\Permission\Models\Role model
Your Permission model needs to extend the CodeMaster\Permission\Models\Permission model

If you need to REPLACE the existing Role or Permission models you need to keep the following things in mind:

Your Role model needs to implement the CodeMaster\Permission\Contracts\Role contract
Your Permission model needs to implement the CodeMaster\Permission\Contracts\Permission contract

In BOTH cases, whether extending or replacing, you will need to specify your new models in the configuration. To do this you must update the models.role and models.permission values in the configuration file after publishing the configuration with this command:

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

Cache

Role and Permission data are cached to speed up performance.

While we recommend not changing the cache "key" name, if you wish to alter the expiration time you may do so in the config/permission.php file, in the cache array. Note that as of v2.26.0 the cache entry here is now an array, and expiration_time is a sub-array entry.

When you use the built-in functions for manipulating roles and permissions, the cache is automatically reset for you, and relations are automatically reloaded for the current model record:

$user->assignRole('writer');
$user->removeRole('writer');
$user->syncRoles(params);
$role->givePermissionTo('edit articles');
$role->revokePermissionTo('edit articles');
$role->syncPermissions(params);
$permission->assignRole('writer');
$permission->removeRole('writer');
$permission->syncRoles(params);

HOWEVER, if you manipulate permission/role data directly in the database instead of calling the supplied methods, then you will not see the changes reflected in the application unless you manually reset the cache.

Manual cache reset

To manually reset the cache for this package, you can run the following in your app code:

$this->app->make(\CodeMaster\Permission\PermissionRegistrar::class)->forgetCachedPermissions();

Or you can use an Artisan command:

php artisan permission:cache-reset

Cache Identifier

TIP: If you are leveraging a caching service such as redis or memcached and there are other sites running on your server, you could run into cache clashes between apps. It is prudent to set your own cache prefix in Laravel's /config/cache.php to something unique for each application. This will prevent other applications from accidentally using/changing your cached data.

Need a UI?

The package doesn't come with any screens out of the box, you should build that yourself. Here are some options to get you started:

Testing

composer test

Upgrading

If you're upgrading from v1 to v2, @fabricecw prepared a gist which may make your data migration easier. You will also need to remove your old laravel-permission.php config file and publish the new one permission.php, and edit accordingly.
