Laravel - 关闭关系的过滤器集合

Question

Wondering if there is a way to use closure on a relationship in order to filter the whole line if there isn't a value which corresponds?

Example code:

foreach ($paiementMethods as $value) {
            $giftCards = GiftCard::with(['userEntered', 'userEmployee', 'client', 'payement', 'payement.payementMethods' => function($query) use ($value)
            {
                $query->where('id', $value);
            }])
            ->where('date','>=', $dateStart)
            ->where('date','<=', $dateEnd)
            ->orderBy('updated_at', 'desc')->get();

            $giftCardsCollection = $giftCardsCollection->merge($giftCards);
        }
    }

In this example, if $query->where doesn't find a row for the payement.payementMethods which matches the $value , I want the giftCard to return null. The result I get is the giftCard with only the relation on payement.payementMethods being empty .

My other solution would be to query the giftCard and after that checking the $value to see if I have to include the giftCard in the collection or not.

Best regards

I think using whereHas , it can be solved

$giftCards = GiftCard::with(['userEntered', 'userEmployee', 'client', 'payement', 'payement.payementMethods'])
        ->whereHas( 'payement.payementMethods', function($query) use ($paiementMethods) {
        $query->whereIn('id', $paiementMethods);
    })
        ->where('date','>=', $dateStart) 
        ->where('date','<=', $dateEnd) 
        ->orderBy('updated_at', 'desc')
        ->get();
