withCount() for multiple levels?

Like you can do Project::with('events.contacts') can you also do Project::withCount('events.contacts') ? It doesn’t seem to work. Is there another way to find the total count of contacts for all events for a certain project where project.id = event.project_id and event.id = contact.event_id

Method 1

You can use relationship Has Many Through

Docs: https://laravel.com/docs/8.x/eloquent-relationships#has-many-through

<?php

namespace AppModels;

use IlluminateDatabaseEloquentModel;

class Project extends Model
{
    public function contacts()
    {
        return $this->hasManyThrough(Contact::class, Event::class);
    }
}

Then you can do
Project::withCount('contacts')->get();
