Adding primaryKey to Models

[Ifnir]

Atm I have trouble updating a variant through a relation.

$product = Product::where('id', '=', $productitem->Id)->first();
$productVariant[] = new ProductVariant([
'Price' => 7700]);

if( $product) $product->variants()->first()->save($productVariant);

This example code above returns "True", but doesn't update anything.
What I researched so far for why it only return "True" is, that there isn't really a explanation except primary key in model is being overwritten

So can we test if adding
protected $primaryKey = "id"
to "ProductVariant" model fixes the issue?
