+# Nova Order Field nestedset
+
+A field that make your resources orderable using [the laravel nestedset package](https://github.com/lazychaser/laravel-nestedset).
+
+## Requirements
+
+* PHP >= 7.1
+* Laravel Nova >= 2.0
+* Laravel Framework 5.8+
+
+## Installation
+
+```sh
+composer require novius/laravel-nova-order-nestedset-field
+```
+
+## Usage
+
+**Step 1**
+
+Use Kalnoy\Nestedset `NodeTrait` and Novius\LaravelNovaOrderNestedsetField `Orderable` trait on your model. 
+
+Example :
+
+```php
+use Kalnoy\Nestedset\NodeTrait;
+use Novius\LaravelNovaOrderNestedsetField\Traits\Orderable;
+
+class Foo extends Model {
+    use NodeTrait;
+    use Orderable;
+
+    public function getLftName()
+    {
+        return 'left';
+    }
+
+    public function getRgtName()
+    {
+        return 'right';
+    }
+
+    public function getParentIdName()
+    {
+        return 'parent';
+    }
+}
+
+```
+
+**Step 2**
+
+Add the field to your resource and specify order for your resources.
+
+
+```php
+use Novius\LaravelNovaOrderNestedsetField\OrderNestedsetField;
+
+class FooResource extends Resource
+{       
+    public function fields(Request $request)
+    {
+        return [
+            OrderNestedsetField::make('Order'),
+        ];
+    }
+
+    /**
+     * @param \Illuminate\Database\Eloquent\Builder $query
+     * @param array $orderings
+     * @return \Illuminate\Database\Eloquent\Builder
+     */
+    protected static function applyOrderings($query, array $orderings)
+    {
+        return $query->orderBy('left', 'asc');
+    }
+}
+
+```
+
+**Scoping**
+
+Imagine you have `Menu` model and `MenuItems`. There is a one-to-many relationship
+set up between these models. `MenuItem` has `menu_id` attribute for joining models
+together. `MenuItem` incorporates nested sets. It is obvious that you would want to
+process each tree separately based on `menu_id` attribute. In order to do so, you
+need to specify this attribute as scope attribute:
+
+```php
+    protected function getScopeAttributes()
+    {
+        return ['menu_id'];
+    }
+```
+
+[Retrieve more information about usage on official doc](https://github.com/lazychaser/laravel-nestedset#scoping).
+
+
+## Override default languages files
+
+Run:

+```
+
+## Lint
+
+Run php-cs with:
+
+```sh
+composer run-script lint
+```
