Laravel HasManyThrough Relation with Where Condition on related table

Question

I want to get count of Verified Doctors of a city based on hospital (where doctor works). I have created hasManythrough relation in City modal and when I'm using this relationship in blade file it gives all doctors (verified and unverified). I only want to get verified doctors. Here is my database structure:

Database

doctors (columns) ---id--name---is_verified--

hospitals columns) ---id--city_id---name---

doctor_hospitals (columns) --id--hospital_id---doctor_id

Relation in City Modal

    public function cityDoctors()
    {
        return $this->hasManyThrough(
            'App\DoctorHospital',
            'App\Hospital',
            'city_id',
            'hospital_id'
        );
    }

In Controller

 $cities=City::with('cityDoctors')->whereHas('cityDoctors')->get();

In blade file I use

   @foreach($cities as $city)
     <li><a href="{{route('typeSearch',['type' => 'city', 'id' => $city->id])}}">
        <strong>{{$city->cityDoctors->count()}}</strong>{{$city->name}}</a>
     </li>
   @endforeach

It show count of All doctors(verified and unverified). How to get only verified doctors of city?

it's like many to many relation more than has many throw.

Anyway, you can do it using whereHas inside the eager loading statement (with):

  $cities = City::with(['cityDoctors' => function ($query) {
            $query->whereHas('doctor', function ($query) {
                $query->where('is_verified', true);
            });
        }])->has('cityDoctors')->get();

Make sure of the relation name between CityDoctor and Doctor models
