Polymorphic Laravel Auditing Package - Retrieving polymorphic audits

I am currently using Laravel Auditing (Owen-it) package to audit models automatically which is working great using the following code.

class Staff extends Model implements Auditable
{
   use \OwenIt\Auditing\Auditable;
   use SoftDeletes;

}
class Customer extends Model implements Auditable
{
   use \OwenIt\Auditing\Auditable;
   use SoftDeletes;

}

Seeing as there is a significant number of fields (> 20) on these classes I am intending to convert these classes to a polymorphic relationship where all common fields reside in the base class and any class unique properties will go in their respective classes.

For example - the base class:

class User extends Model implements Auditable
{
   use \OwenIt\Auditing\Auditable;
   use SoftDeletes;

} 

Currently I use something like this to retrieve audits:

$staff = App\Model\Staff::find($id);
$allAudits= $staff->audits;

My question is then is there a clean way to retrieve all audits across the base and morphed class?

Thanks in advance.

You could add the following method to your base class in order to fetch all audits:

public function getAllAudits(): Collection
{
    return Audit::where(function ($query) {
        $query->where('auditable_type', get_class($this))
            ->where('auditable_id', $this->id);
    })
    ->orWhere(function ($query) {
        $morph = $this->userable; // or whatever morph relation name you have set

        $query->where('auditable_type', get_class($morph))
            ->where('auditable_id', $morph->id);
    })
    ->get();
}
