Dynamic polymorphic relation

[ju5t]

We have the following relationship defined:

public function detail(): MorphOne
{
    return $this->morphOne($this->getProductTypeAttribute(), 'detailable');
}

As you can see this only works on an instantiated model. It's not possible to use it in the query builder. This isn't necessarily something we have a problem with, but we'd like to kill all of our n+1 queries.

getProductTypeAttribute has some logic to convert an integer value that's stored with the model, to a class name that's stored elsewhere. This could be an Enum too.

Is there something I can do to make this n+1 proof?
