This Laravel Nova package allows you to reorder models in a Nova resource's index view using drag & drop.

Uses Spatie's eloquent-sortable under the hood.

• php: >=8.0
• laravel/nova: ^4.24.0

• Drag & drop reorder (on either Index view or HasMany view)
• BelongsTo/MorphsTo reorder support w/ pivot tables
• Move to start and end arrows (makes item first/last)
• Everything from eloquent-sortable
• Localization

Install the package in a Laravel Nova project via Composer:

# Install package
composer require outl1ne/nova-sortable

Add an order field to the model using Laravel migrations:

// Add order column to the model
Schema::table('some_model', function (Blueprint $table) {
  $table->integer('sort_order');
});

// Set default sort order (just copy ID to sort order)
DB::statement('UPDATE some_model SET sort_order = id');

Implement the Spatie's eloquent-sortable interface and apply the trait:

use Spatie\EloquentSortable\Sortable;
use Spatie\EloquentSortable\SortableTrait;

class SomeModel extends Eloquent implements Sortable
{
  use SortableTrait;

  public $sortable = [
    'order_column_name' => 'sort_order',
    'sort_when_creating' => true,
  ];

  ...
}

When the model does not have a sortable configuration, the default eloquent-sortable configuration will be used.

Apply HasSortableRows trait from this package on the Resource:

use Outl1ne\NovaSortable\Traits\HasSortableRows;

class MyResource extends Resource
{
  use HasSortableRows;

  ...
}

NB! This overrides the indexQuery() method.

You can disable sorting on a per-request or per-resource basis by overriding the canSort() on the Resource method like so:

public static function canSort(NovaRequest $request, $resource)
{
  // Do whatever here, ie:
  // return user()->isAdmin();
  // return $resource->id !== 5;
  return true;
}

NB! This requires you to disable caching (see below).

If you want to disable caching due to using canSort or running tests, you can set sortableCacheEnabled to false on the resource that has the HasSortableRows trait. See the example below:

class Artist extends Resource
{
    use HasSortableRows;

    public static $sortableCacheEnabled = false;
}

Or if you want to temporarily disable sortability cache (for tests), you can call Resource::disableSortabilityCache() on the resource.

To sort your resource in a different order in Nova, you can set the nova_order_by flag to DESC (ASC by default) in the $sortable array.

class SomeModel extends Eloquent implements Sortable
{
  use SortableTrait;

  public $sortable = [
    'order_column_name' => 'sort_order',
    'sort_when_creating' => true,
    'nova_order_by' => 'DESC',
  ];

  ...
}

If you have a resource that has authorizedToUpdate false, but you want the user to still be able to sort it, you can use the ignore_policies flag like so:

class SomeModel extends Eloquent implements Sortable
{
  use SortableTrait;

  public $sortable = [
    'order_column_name' => 'sort_order',
    'sort_when_creating' => true,
    'ignore_policies' => true,
  ];

  ...
}

NB! The resource can only be sorted on either the Index view or the HasMany list view, but not both!

Sorting on HasMany is simple. Add 'sort_on_has_many' => true to the $sortable array on the model. Like so:

public $sortable = [
  'order_column_name' => 'sort_order',
  'sort_when_creating' => true,
  'sort_on_has_many' => true,
];

The sort on has many configuration can be apply in a per model basis or it can be added in the eloquent-sortable configuration for all the models.

return [

    // Spatie sortable configuration

    /**
     * Add sort on has many in all the models.
     **/
    'sort_on_has_many' => true,
];

Sorting on BelongsToMany and MorphToMany relationships is available, but requires special steps.

See the documentation here: Sorting ManyToMany relationships (w/ pivot table).

The translation file(s) can be published by using the following publish command:

php artisan vendor:publish --provider="Outl1ne\NovaSortable\ToolServiceProvider" --tag="translations"

You can add your translations to resources/lang/vendor/nova-sortable/ by creating a new translations file with the locale name (ie et.json) and copying the JSON from the existing en.json.

This package overwrites the indexQuery of the Resource and if you still want to use it, you can do it as follows:

use HasSortableRows {
    indexQuery as indexSortableQuery;
}

public static function indexQuery(NovaRequest $request, $query)
{
  // Do whatever with the query
  // ie $query->withCount(['children', 'descendants', 'modules']);
  return parent::indexQuery($request, static::indexSortableQuery($request, $query));
}
