Defining Resources
In Laravel Nova, you can define resources that represent your database tables. Each resource corresponds to a model in your Laravel application.
1. Creating a Resource:
You can create a new resource using the Artisan command:
|
1 |
php artisan nova:resource Post |
This command generates a new resource file located in app/Nova/Post.php.
2. Defining Fields:
In the resource file, you can define the fields that should be displayed in the Nova interface:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
namespace App\Nova; use Illuminate\Http\Request; use Laravel\Nova\Fields\ID; use Laravel\Nova\Fields\Text; use Laravel\Nova\Fields\Trix; class Post extends Resource { public static $model = \App\Models\Post::class; public function fields(Request $request) { return [ ID::make()->sortable(), Text::make('Title') ->sortable() ->rules('required', 'max:255'), Trix::make('Content') ->rules('required'), ]; } } |
Customizing the Dashboard
You can customize the Nova dashboard to display metrics and insights about your application.
1. Creating a Dashboard:
You can create a custom dashboard using the following command:
|
1 |
php artisan nova:dashboard MyDashboard |
This command generates a dashboard file in app/Nova/Dashboards/MyDashboard.php.
2. Defining Metrics:
You can define metrics to display key performance indicators on your dashboard:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
namespace App\Nova\Dashboards; use Laravel\Nova\Dashboard; use Laravel\Nova\Metrics\Value; class MyDashboard extends Dashboard { public function cards() { return [ new Value('Total Posts', \App\Models\Post::count()), ]; } } |
Implementing Filters
You can create filters to allow users to narrow down resource data based on specific criteria.
1. Creating a Filter:
You can create a filter using the following command:
|
1 |
php artisan nova:filter PostStatus |
2. Defining the Filter Logic:
In the filter file, define the logic to filter the resources:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
namespace App\Nova\Filters; use Illuminate\Http\Request; use Laravel\Nova\Filters\Boolean; class PostStatus extends Boolean { public function apply(Request $request, $query, $value) { return $query->where('status', $value); } public function options() { return [ 'Published' => true, 'Draft' => false, ]; } } |
Authorization and Policies
You can leverage Laravel’s built-in authorization features to manage access to resources and actions in Nova.
1. Defining Policies:
Create a policy for your model using the Artisan command:
|
1 |
php artisan make:policy PostPolicy |
2. Registering Policies:
Register the policy in your AuthServiceProvider:
|
1 2 3 |
protected $policies = [ \App\Models\Post::class => \App\Policies\PostPolicy::class, ]; |
3. Using Policies in Resources:
In your resource class, you can use the authorize method to restrict access:
|
1 2 3 4 |
public function authorizedToView(Request $request) { return $request->user()->can('view', $this->model()); } |
