README

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 or a subset group of records of that model + 1.

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

This package is a fork of the popular spatie/eloquent-sortable with added functionality to allow sorting on subsets of models as well as moving a model to a specific position.

Thank you to Freek Van der Herten for sharing the original package.

Installation

This package can be installed through Composer.

composer require metrixinfo/eloquent-sortable

Usage

To add sortable behaviour to your model you must:

Use the trait Metrix\EloquentSortable\Sortable.
Optionally specify which column will be used as the order column. The default is display_order.

Examples

Simple ordered model

use Metrix\EloquentSortable\Sortable;

class MyModel extends Eloquent
{

    use SortableTrait;

    public $sortable = [
        'sort_on_creating' => true,
        'order_column'      => 'display_order',
    ];
    
    ...
}

Ordered model with a grouping column

use Metrix\EloquentSortable\Sortable;

class MyModel extends Eloquent
{

    use SortableTrait;

    public $sortable = [
        'sort_on_creating'  => true,
        'order_column'      => 'display_order',
        'group_column'      => 'group_id',
    ];
    
    ...
}

Ordered model grouped on multiple columns

use Metrix\EloquentSortable\Sortable;

class MyModel extends Eloquent
{

    use SortableTrait;

    public $sortable = [
        'sort_on_creating'  => true,
        'order_column'      => 'display_order',
        'group_column'      => ['group_id','user_id'],
    ];
    
    ...
}

If you don't set a value for $sortable['order_column'] the package will assume an order column name of display_order.

If you don't set a value $sortable['sort_on_creating'] the package will automatically assign the next highest order value to the 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 an ordered query scope. All models will be returned ordered by 'group' and then 'display_order' if you have not applied a where() method for your group column on your query,

$orderedRecords = MyModel::ordered()->get();

$groupedOrderedRecords = MyModel::where('group_id', 2)->ordered()->get();

$allRecords = 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 record_column value 1
 * the record for model id 1 will have record_column value 2
 * the record for model id 2 will have record_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 record_column value 11
 * the record for model id 1 will have record_column value 12
 * the record for model id 2 will have record_column value 13
 */
MyModel::setNewOrder([3,1,2], 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);

You can move a model to a specific position:

$myModel->moveToPosition(4);

Tests

The package contains some integration/smoke tests, set up with Orchestra. The tests can be run via the ./bin/test.sh script from the root directory.
