Description

When I try to access an Attribute within another Attribute I receive the following error:

Undefined array key "path"

Is this an expected behavior?

Here is my File model:

<?php

namespace App\Models;

use App\Core\Traits\HasUuid;
use Illuminate\Database\Eloquent\Casts\Attribute;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\MorphTo;
use Illuminate\Support\Facades\Storage;

class File extends Model
{
    use HasFactory,
        HasUuid;

    protected $fillable = [
        'uuid',
        'context',
        'mimetype',
        'extension'
    ];

    protected $appends = [
        'path',
        'url'
    ];


    public function fileable(): MorphTo
    {
        return $this->morphTo();
    }


    public function path(): Attribute
    {
        return Attribute::make(
            get: function (
                mixed $value,
                array $attributes
            ) {
                return $attributes['context'] . '/' . $attributes['uuid'] . '.' . $attributes['extension'];
            }
        );
    }

    public function url(): Attribute
    {
        return Attribute::make(
            get: function (
                mixed $value,
                array $attributes
            ) {
                return Storage::publicUrl($attributes['path']);
            }
        );
    }
}

Steps To Reproduce

I'm just returning the Attribute in a resource:

<?php

namespace App\Http\Resources\File;

use Illuminate\Http\Request;
use Illuminate\Http\Resources\Json\JsonResource;

class FileResource extends JsonResource
{
    public function toArray(
        Request $request
    ): array
    {
        return [
            'id' => $this->uuid,
            'url' => $this->url,
            'mimetype' => $this->mimetype,
            'extension' => $this->extension,
            'created_at' => $this->created_at,
            'updated_at' => $this->updated_at
        ];
    }
}

Hello, I don't think that you can access it from within another accessor as appends array will not be triggered anymore here.

What about the following code :

// using magic attribute
return Storage::publicUrl($this->path);

// using getAttribute() method
return Storage::publicUrl($this->getAttribute('path'));

You can access with `$this->url. Closures are usually bound to the object they are defined in...
