[BUG]: saving model with mutliple fields relation is "not implemented"

[bakos]

Describe the bug

When i try to save model with this relation: https://docs.phalcon.io/5.0/pl-pl/db-models-relationships#multiple-fields
it couses exception: Not implemented
trace lead to phalcon/Mvc/Model.zep line 4962 or in 5081 (i got both lines in some tests)

It was working on v3 and v4.

To Reproduce

Provide output if related. Provide coredump if any. Use https://docs.phalcon.io/en/latest/generating-backtrace as reference.

Steps to reproduce the behavior:

models like in docs

       /** @var Products $product */
        $product = Products::findFirst();
        $product->prd_name = $product->parts->par_name;
        try {
            $product->save();
        } catch (\Exception $e) {
            var_dump($e->getMessage());
            var_dump($e->getFile());
            var_dump($e->getLine());
        }

string(15) "Not implemented"

[zikezhang]

it's prd_name defined in the model?

[bakos]

@zikezhang yes it is. models to the example were taken from documentation:

https://docs.phalcon.io/5.0/pl-pl/db-models-relationships#multiple-fields

I had a problem with that in a project where relation is more complicated. But again - it was working in previous versions of phalcon (v3, v4) so something changed.
