Use filter set up in relationship's filter about eloquentfilter

[Tucker-Eric]

They way you have this set up, if you pass a name parameter to your CaseEntityFilter it will automatically forward that to the name method on PatientFilter because name is present in your $relations['patient'] array. That array is also setup to forward a firstName parameter to PatientFilter::firstName() (if it exists) and patient_name to PatientFilter::patientName() (if it exists) without having to define any methods on CaseEntityFilter.

If you want to use a patient_name parameter to call a patientName() method on your CaseEntityFilter that will call the name() on PatientFilter then you can do it like:

class CaseEntityFilter extends ModelFilter
{
    // Cant seem to get this to point to the method on the actual filter
    public $relations = [
        'patient' => [
            'name',
            'firstName'
        ]
    ];

    public function patientName($name)
    {
        return $this->related('patient', function($query) use ($name) {
            // $query here is an instance of the `patient` relation's query builder
            return $query->filter(['name' => $name]);
        });
    }

Aha. The $query->filter() portion was exactly what I was looking for. Thanks again!
