Laravel – Why larastan raise error on relationLoaded method in resource file?

In resource file app/Http/Resources/PostResource.php I use method :

<?php

namespace AppHttpResources;

use IlluminateHttpResourcesJsonJsonResource;

class PostResource extends JsonResource
{
    public function toArray($request)
    {
        $data = [
            'id' => $this->id,
            ...
            'mediaProp'=> $this->when($this->relationLoaded('mediaProp'), new MediaPropResource($this->mediaProp)),
        ];

But I got error when running larastan command :
Call to an undefined method AppHttpResourcesPostResource::relationLoaded()

I added PostResource class into phpstan.neon under universalObjectCratesClasses key:

includes:
    - ./vendor/nunomaduro/larastan/extension.neon

parameters:
    universalObjectCratesClasses:
        - IlluminateHttpResourcesJsonJsonResource
        - AppHttpResourcesPostResource

    paths:
        - app/

    # Level 9 is the highest level
    level: 5

#    ignoreErrors:
#        - '#PHPDoc tag @var#'
#
#    excludePaths:
#        - ./*/*/FileToBeExcluded.php
#
#    checkMissingIterableValueType: false

But that does not help and i still got the same error. How can I fix it ?

"laravel/framework": "^10.8",
"nunomaduro/larastan": "^2.0",

Thanks in advance!

    This is interesting because among my codes there is a code snippet similar to yours:

    'kerzz_pos' => $this->when(
                 $this->relationLoaded('attributes') && $this->isKerzzAttributeExist(),
                 fn () => PanelBranchAttributeResource::collection($this->getKerzzAttributes())
             ),

    And I use "nunomaduro/larastan": "^2.6.4". It doesn’t give me any errors either.

    Maybe you just need to upgrade the package. Or if you want to ignore it you can write a regex under the ignoreErrors setting like this:

    ignoreErrors:
     - '#Call to an undefined method (.*?)::relationLoaded().#'

    relationLoaded is a method that is defined in HasRelationships trait of Laravel. But PHPStan does not know the relation between a resource and model. So you need to add a @mixin annotation to your resource class. Like so:

    <?php

namespace AppHttpResources;

use IlluminateHttpResourcesJsonJsonResource;

/** @mixin Post */
class PostResource extends JsonResource
....

    Of course adjust the model namespace for your use case.
