Sortable behaviour for Eloquent models

This package provides a trait that adds sortable behaviour to an Eloquent model.

The value of the order column of a new record of a model is determined by the maximum value of the order column of all records of that model + 1.

The package also provides a query scope to fetch all the records in the right order.

Installation

This package can be installed through Composer.

composer require spatie/eloquent-sortable

In Laravel 5.5 and above the service provider will automatically get registered. In older versions of the framework just add the service provider in config/app.php file:

'providers' => [
    ...
    Spatie\EloquentSortable\EloquentSortableServiceProvider::class,
];

Optionally you can publish the config file with:

php artisan vendor:publish --provider="Spatie\EloquentSortable\EloquentSortableServiceProvider" --tag="config"

This is the content of the file that will be published in config/eloquent-sortable.php

return [
  /*
   * The name of the column that will be used to sort models.
   */
  'order_column_name' => 'order_column',

  /*
   * Define if the models should sort when creating. When true, the package
   * will automatically assign the highest order number to a new model
   */
  'sort_when_creating' => true,
];

Usage

To add sortable behaviour to your model you must:

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

Example

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

class MyModel extends Eloquent implements Sortable
{

    use SortableTrait;

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

    ...
}

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

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

Assuming that the db-table for MyModel is empty:

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

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

$myModel = new MyModel();
$myModel->save(); // order_column 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 order_column value 1
 * the record for model id 1 will have order_column value 2
 * the record for model id 2 will have order_column 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 order_column value 11
 * the record for model id 1 will have order_column value 12
 * the record for model id 2 will have order_column 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 order_column value 1
 * the record for model uuid '40324562-c7ca-4c69-8018-aff81bff8c95' will have order_column value 2
 * the record for model uuid '5dc4d0f4-0c88-43a4-b293-7c7902a3cfd1' will have order_column 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 order_column value 10
 * the record for model uuid '40324562-c7ca-4c69-8018-aff81bff8c95' will have order_column value 11
 * the record for model uuid '5dc4d0f4-0c88-43a4-b293-7c7902a3cfd1' will have order_column 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);

Grouping

If your model/table has a grouping field (usually a foreign key): id, user_id, title, order_column and you'd like the above methods to take it into considerations, you can create a buildSortQuery method at your model:

  public function buildSortQuery()
    {
        return static::query()->where('user_id', $this->user_id);
    }

This will restrict the calculations to fields value of the model instance.

Tests

The package contains some integration/smoke tests, set up with Orchestra. The tests can be run via phpunit.
