Custom Object in pipeline

[kapdom]

How to pass custom object from one method to another.

For example in first method (parse) I grab collection of items and in for each loop I added new entry to DB and create eloquent object. Next I would like to for each element call another request and parse in another method but I need to pass Object to that parse method as well.
How can I do it?

public function parse(Response $response): Generator
    {
        $linksObject = $response
            ->filter('a.make');

        foreach ($linksObject as $obj) {
            $carBrand = Brand::firstOrCreate(['name' => trim($obj->textContent)]);
            $url = $obj->getAttribute('href');
           
            $this->request(
                'GET',
                 self::BASE_URI.$url,
                'getModels',
            
            );
        }
    }

public function getModels(Response $response, Brand $brand): \Generator
    {
        $models = $response->filter('.model-selector-box');
        foreach ($models as $model) {
            $url = $model->getAttribute('href');
            $model = trim($model->getElementsByTagName('h2')[0]->nodeValue);
            $realUrl = self::BASE_URI.$url;
            yield $this->request(
                'GET',
                $realUrl,
                'getGeneration'
            );
        }
    }

I moved this to a discussion as it's more of a question and less of an issue.

To answer your question, dispatch a custom request and store the model (or model ID) inside the request's meta data. You can then access this meta data via the $response->getRequest()->getMeta(...) method on the Response object.

Something like this:

public function parse(Response $response): Generator
{
    // process the response...

    $request = (new Request('GET', $url, [$this, 'getModels']))
        ->withMeta('modelId', $brand->id);

    yield ParseResult::fromValue($request);
}

public function getModels(Response $response): Generator
{
    $model = Brand::find($response->getRequest()->getMeta('modelId'));

    // ...
}
