How to use a relationship in Laravel Accessor

Imagine, you have to use a relation within your Model Accessor. Let’s see our Post Model example:

// Appending the Accessor name
protected $appends = ['seo_title'];

// The Relationship
public function platform()
{
    return $this->belongsTo(Platform::class)->withDefault();
}

// The Accessor
protected function seoTitle(): Attribute {
    
    return Attribute::make(
        get: function ($value, $attributes) {

            if (!empty($attributes['payment_id'])) {

                if ($attributes['payment_id'] == 2) {
                    $value = 'Online course '.$attributes['title'].' by '.$this->platform->name;
                } else {
                    $value = 'Free online course '.$attributes['title'].' by '.$this->platform->name;
                }

            } else {
                $value = $attributes['title'];
            }              

            return $value;

        }
    );
}    

As you see, we reference the relation with this code – $this->platform->name. Don’t forget that you have to “camel case” seoTitle for your accessor method name, and use it as a “snake case” seo_title in your Blade file or in the Controller.

In your Blade file:

{{ $post->seo_title }}

The Model Accessors make the developer’s life so easy! Enjoy
