Sortable behaviour for Eloquent models

@thanks spatie/eloquent-sortable

Installation

This package can be installed through Composer.

composer require silverd/laravel-sortable:dev-master

Optionally you can publish the config file with:

php artisan vendor:publish --provider="Silverd\LaravelSortable\ServiceProvider"

Usage

To add sortable behaviour to your model you must:

1. Implement the Silverd\LaravelSortable\Sortable interface.
2. Use the trait Silverd\LaravelSortable\SortableTrait.
3. Optionally specify which column will be used as the order column. The default is weight.

Example

use Silverd\LaravelSortable\Sortable;
use Silverd\LaravelSortable\SortableTrait;

class MyModel extends Eloquent implements Sortable
{
    use SortableTrait;

    public $sortable = [
        'sort_column_name' => 'weight',
        'sort_when_creating' => 'end',
    ];
    ...
}

If you don't set a value $sortable['sort_column_name'] the package will assume that your order column name will be named weight.

If you don't set a value $sortable['sort_when_creating'] the package will automatically assign the lowest order number to a new model;

Assuming that the db-table for MyModel is empty:

$myModel = new MyModel();
$myModel->save(); // weight for this record will be set to 1

$myModel = new MyModel();
$myModel->save(); // weight for this record will be set to 2

$myModel = new MyModel();
$myModel->save(); // weight for this record will be set to 3


//the trait also provides the ordered query scope
$orderedRecords = MyModel::ordered()->get();

You can set a new order for all the records using the setNewOrder-method

/**
 * the record for model id 3 will have weight value 1
 * the record for model id 1 will have weight value 2
 * the record for model id 2 will have weight value 3
 */
MyModel::setNewOrder([3,1,2]);

Optionally you can pass the starting order number as the second argument.

/**
 * the record for model id 3 will have weight value 11
 * the record for model id 1 will have weight value 12
 * the record for model id 2 will have weight value 13
 */
MyModel::setNewOrder([3,1,2], 10);

To sort using a column other than the primary key, use the setNewOrderByCustomColumn-method.

/**
 * the record for model uuid '7a051131-d387-4276-bfda-e7c376099715' will have weight value 1
 * the record for model uuid '40324562-c7ca-4c69-8018-aff81bff8c95' will have weight value 2
 * the record for model uuid '5dc4d0f4-0c88-43a4-b293-7c7902a3cfd1' will have weight value 3
 */
MyModel::setNewOrderByCustomColumn('uuid', [
   '7a051131-d387-4276-bfda-e7c376099715',
   '40324562-c7ca-4c69-8018-aff81bff8c95',
   '5dc4d0f4-0c88-43a4-b293-7c7902a3cfd1'
]);

As with setNewOrder, setNewOrderByCustomColumn will also accept an optional starting order argument.

/**
 * the record for model uuid '7a051131-d387-4276-bfda-e7c376099715' will have weight value 10
 * the record for model uuid '40324562-c7ca-4c69-8018-aff81bff8c95' will have weight value 11
 * the record for model uuid '5dc4d0f4-0c88-43a4-b293-7c7902a3cfd1' will have weight value 12
 */
MyModel::setNewOrderByCustomColumn('uuid', [
   '7a051131-d387-4276-bfda-e7c376099715',
   '40324562-c7ca-4c69-8018-aff81bff8c95',
   '5dc4d0f4-0c88-43a4-b293-7c7902a3cfd1'
], 10);

You can also move a model up or down with these methods:

$myModel->moveOrderDown();
$myModel->moveOrderUp();

You can also move a model to the first or last position:

$myModel->moveToStart();
$myModel->moveToEnd();

You can swap the order of two models:

MyModel::swapOrder($myModel, $anotherModel);
