README

This package sequentially numbers your Eloquent model instances, constrained by a scope numbered that you customize.

On every created, deleted, updated and restored event, the models in the scope get renumbered.

When the numbering happens, the model that raised the event is injected into the method and can be used to further limit the scope.

Retrieved models will include a number attribute (customizable).

What is this good for? Rankings, positioning, row numbers, the fifth of something – when calculating the number ”on-the-fly“ is not an option.

Installation

Install the package via composer:

composer require m165437/eloquent-numbered

Usage

Add the trait M165437\EloquentNumbered\Numbered to your model:

use Illuminate\Database\Eloquent\Model;
use M165437\EloquentNumbered\Numbered;

class MyModel extends Model
{
    use Numbered;
    ...
}

Add a number field to your model migration:

Schema::create('my_model', function (Blueprint $table) {
    $table->integer('number')->nullable();
    ...
});

If you would like to name this field / attribute differently, set the constant NUMBER on the model accordingly, e.g.

const NUMBER = 'rank';

Configuration

The default numbering scope (included with the trait) sorts the model instances by date in ascending order:

public function scopeNumbered($query, $model = null)
{
    return $query->oldest();
}

If you want to customize the scope, add it to your model.

When the numbering happens, the model that raised the event is injected into the method and can be used to further limit the scope, e.g. numbering the model instances for each user individually:

public function scopeNumbered($query, $model = null)
{
    return $query->oldest()
        ->when($model, function ($query, $model) {
            return $query->where('user_id', $model->user_id)
        });
}
