How in Laravel to link a table with the last record of another by key?

Question

Laravel

goods are stored in one table. The rest is in another. each product corresponds to many rows of the remainder of another table. We need to get the goods and only the last record of the balance. I can't find the syntax.

public function rests() {
        return $this->hasMany('App\Models\ProductRest', 'product_id', 'id');
}

Here, you need to add something like latest() to this code in order to get only one record using the with construction. But something doesn't work.

Answer 1

public function latestRest()
{
    return $this->hasOne(ProductRest::class)->latest();
}
