How laravel assign this to the model given in resources

How Laravel reassigning $this to the model given in Api resources and return the just method in the class technically?

Assume we have this:

new TeamResource(Team::first());

then, in the TeamResrouce when we call $this, its Team model instnace.

and automatically it called toArray() method in the TeamResource class.

without any constructor in exact class, how?

The toArray() call as the toJson() call on model instances is done in the laravel kernel and request pipeline. here is some code

Illuminate\Routing\Router @ toResponse()

 public static function toResponse($request, $response)
    {
        if ($response instanceof Responsable) {
            $response = $response->toResponse($request);
        }

        if ($response instanceof PsrResponseInterface) {
            $response = (new HttpFoundationFactory)->createResponse($response);
        } elseif ($response instanceof Model && $response->wasRecentlyCreated) {
            $response = new JsonResponse($response, 201);
        } elseif (! $response instanceof SymfonyResponse &&
                   ($response instanceof Arrayable ||
                    $response instanceof Jsonable ||
                    $response instanceof ArrayObject ||
                    $response instanceof JsonSerializable ||
                    is_array($response))) {
            $response = new JsonResponse($response);
        } elseif (! $response instanceof SymfonyResponse) {
            $response = new Response($response);
        }

        if ($response->getStatusCode() === Response::HTTP_NOT_MODIFIED) {
            $response->setNotModified();
        }

        return $response->prepare($request);
    }

Magic method (__get):

public function __get($key)
{
    return $this->resource->{$key};
}

The API Resource (Illuminate\Http\Resources\Json\JsonResource) defines this method so you can access the underlying model's attributes by accessing properties on the resource itself.

$this->something === $this->resource->something;

Notice that we can access model properties directly from the $this variable. This is because a resource class will automatically proxy property and method access down to the underlying model for convenient access. Laravel 5.8 Docs - Eloquent - API Resources

I see two possible things, one is I haven't really seen anyone use another class model to initialize a completely different class. Youre problem may be in that way you initialize.

As well you could try assigning $this = TeamsResource(Team::first())
