Belongs To One Relation for Laravel 5.5

Based on Belongs To Many Relation. Returns one model instead of Collection of models.

Installation

composer require megapixel23/belongs-to-one

Usage

BelongsToOne relation is almost identical to standard BelongsToMany except it returns one model instead of Collection of models and null if there is no related model in DB (BelongsToMany returns empty Collection in this case). Include Megapixel23\Database\Eloquent\Relations\BelongsToOneTrait within your Model and use BelongsToOne relation.

Example:

<?php

namespace App\Models;

use App\Models\Group;
Use Illuminate\Database\Eloquent\Model;
use Megapixel23\Database\Eloquent\Relations\BelongsToOneTrait;

class Record extends Model
{
    use BelongsToOneTrait;
    
    public function group()
    {
        return $this->belongsToOne(Group::class);
    }
}

And then use it like any other relation:

$record = Record::with('group')->first();
