There is no such method at the moment. I'll look into adding one.

Sorry I am in a hard development and I really need this function. What is your estimation regarding the time that it will be finished.

If you add all the functions that we have in hasManyDeep library here it would be grate.

Hi. I extended your class and solved my issue. If you like you can use the code. Unfortunately have no time to make a pull request. I will put the code here.

<?php

namespace App\Relations;

use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Model;
use Znck\Eloquent\Relations\BelongsToThrough AS BelongsToThroughParent;

class BelongsToThrough extends BelongsToThroughParent
{
    /**
     * Create a new belongs to through relationship instance.
     *
     * @param \Illuminate\Database\Eloquent\Builder $query
     * @param \Illuminate\Database\Eloquent\Model $parent
     * @param \Illuminate\Database\Eloquent\Model[] $throughParents
     * @param string|null $localKey
     * @param string $prefix
     * @param array $foreignKeyLookup
     * @return void
     */
    public function __construct(Builder $query, Model $parent, array $throughParents, $localKey = null, $prefix = '', array $foreignKeyLookup = [])
    {
        parent::__construct($query, $parent, $throughParents, $localKey, $prefix, $foreignKeyLookup);
    }

    public function getThroughParents(){
        return $this->throughParents;
    }

    public function getPrefix(){
        return $this->prefix;
    }

    /**
     * Get the foreign key for a model.
     *
     * @return string[]
     */
    public function getForeignKeys()
    {
        $models = $this->throughParents;
        $foreignKeys = [$this->getForeignKeyName($this->getRelated())];
        foreach($models as $model){
            array_push($foreignKeys, $this->getForeignKeyName($model));
        }
        return $foreignKeys;
    }

    /**
     * Get the foreign key for a model.
     *
     * @return string[]
     */
    public function getLocalKeys()
    {
        $models = $this->throughParents;
        $foreignKeys = [$this->getRelated()->getKeyName()];
        foreach($models as $model){
            array_push($foreignKeys, $model->getKeyName());
        }
        return $foreignKeys;
    }
}
