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 records of that model + 1.

Installation

This package can be installed through Composer.

composer require james.xue/laravel-sortable

Usage

To add sortable behaviour to your model you must:

1. Use the trait James\Sortable\SortableTrait;;

   Use the trait James\Sortable\Sortable;

2. Optionally specify which column will be used as the order column. The default is sort_field.

Example

use James\Sortable\SortableTrait;
use James\Sortable\Sortable;

class MyModel extends Eloquent implements Sortable
{

    use SortableTrait;

    public $sortable = [
        'sort_field' => 'view',
        'sort_when_creating' => true,
    ];
    
    ...
}

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

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(); // sort_field for this record will be set to 1

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

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

You can also move a model:

$myModel = new MyModel();
$myModel->where('id', $id)->first()->move('up'); // up、down、top、end
