Set Default Value for Relationships in Laravel Models

1 year ago admin Laravel

When working with Laravel relationships sometimes the relationship returns null and triggers an error, so to avoid that we need to give the relationship a default value.


Set the default value for the relationship

We assume that we have a Post Model that belongs to a user that has been removed, and when we try to get the user's name through the relationship, we get an error 'trying to access property of non-object', so to solve this problem we give the relationship a default value for the user's name.

                                                        
                                                                                                                        
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use HasFactory;

    public function user()
    {
        return $this->belongsTo(User::class)->withDefault([
            'name' => 'N/A'
        ]);
    }
}
