Custom foreign Key

[jmicarus12]

`public function city() { return $this->belongsTo(City::class); }

public function province() { return $this->belongsToThrough(Province::class, City::class); }

public function posting_city() { return $this->belongsTo(City::class, 'posting_city_id'); }

public function posting_province() { return $this->belongsToThrough(Province::class, City::class, 'posting_city_id'); }`

Is it possible to have a custom foreign key on belongsToThorugh ? I tried the current code but its not working.

Do you mean like this?

public function posting_province()
{
    return $this->belongsToThrough(
        Province::class,
        City::class,
        null,
        '',
        [City::class => 'posting_city_id']
    );
}
