A Laravel Nova tool for the Spatie Permission package

This Nova tool lets you:

• manage roles and permissions on the Nova dashboard
• use permissions based authorization for Nova resources

Screenshots

Requirements & Dependencies

There are no PHP dependencies except the Laravel Nova package and the Spatie Permission package.

Installation

You can install this tool into a Laravel app that uses Nova via composer:

composer require insenseanalytics/laravel-nova-permission

Next, if you do not have package discovery enabled, you need to register the provider in the config/app.php file.

'providers' => [
    ...,
    InsenseanalyticsLaravelNovaPermissionNovaPermissionServiceProvider::class,
]

Next, you must register the tool with Nova. This is typically done in the tools method of the NovaServiceProvider.

// in app/Providers/NovaServiceProvider.php

public function tools()
{
    return [
        // ...
        InsenseanalyticsLaravelNovaPermissionLaravelNovaPermission::make(),
    ];
}

Next, add MorphToMany fields to your app/Nova/User resource:

use LaravelNovaFieldsMorphToMany;

public function fields(Request $request)
{
    return [
        // ...
        MorphToMany::make('Roles', 'roles', InsenseanalyticsLaravelNovaPermissionRole::class),
        MorphToMany::make('Permissions', 'permissions', InsenseanalyticsLaravelNovaPermissionPermission::class),
    ];
}

Finally, add the ForgetCachedPermissions class to your config/nova.php middleware like so:

// in config/nova.php
'middleware' => [
	'web',
	Authenticate::class,
	DispatchServingNovaEvent::class,
	BootTools::class,
	Authorize::class,
	InsenseanalyticsLaravelNovaPermissionForgetCachedPermissions::class,
],

Localization

You can use the artisan command line tool to publish localization files:

php artisan vendor:publish --provider="InsenseanalyticsLaravelNovaPermissionNovaPermissionServiceProvider"

Using Custom Role/Permission Resource Classes

If you want to use custom resource classes you can define them when you register a tool:

// in app/Providers/NovaServiceProvider.php

public function tools()
{
    return [
        // ...
        InsenseanalyticsLaravelNovaPermissionLaravelNovaPermission::make()
            ->roleResource(CustomRole::class)
            ->permissionResource(CustomPermission::class),
    ];
}

Permissions Based Authorization for Nova Resources

By default, Laravel Nova uses Policy based authorization for Nova resources. If you are using the Spatie Permission library, it is very likely that you would want to swap this out to permission based authorization without the need to define Authorization policies.
To do so, you can use the PermissionsBasedAuthTrait and define a permissionsForAbilities static array property in your Nova resource class like so:

// in app/Nova/YourNovaResource.php

class YourNovaResource extends Resource
{
    use InsenseanalyticsLaravelNovaPermissionPermissionsBasedAuthTrait;

    public static $permissionsForAbilities = [
      'all' => 'manage products',
    ];
}

The example above means that all actions on this resource can be performed by users who have the “manage products” permission. You can also define separate permissions for each action like so:

public static $permissionsForAbilities = [
      'viewAny' => 'view products',
      'view' => 'view products',
      'create' => 'create products',
      'update' => 'update products',
      'delete' => 'delete products',
      'restore' => 'restore products',
      'forceDelete' => 'forceDelete products',
      'addAttribute' => 'add product attributes',
      'attachAttribute' => 'attach product attributes',
      'detachAttribute' => 'detach product attributes',
    ];

Relationships

To allow your users to specify a relationship on your model, you will need to add another permission on the Model.
For example, if your Product belongs to User, add the following permission on app/Nova/User.php. :

public static $permissionsForAbilities = [
      'addProduct' => 'add user on products'
    ];
