Cannot query with an array position

[Nicolas Zein]

Hello

I'm using jenssegers/mongodb: ^3.9,

I know i am using an older version but it's impossible for me to update now as i am in production and i have no time to upgrade right now.

I have this query below

$stockedProducts = ProductsDetails::query()
->where('seller_uid', '=', $seller->UID)
->where('locations.location', '=', $locationUid)
->where('locations.quantity_stock', '=', 0);

but it is returning items that do not have a 0 stock because i am not able to isolate the location in the query. If a product has any location at all that carries a 0 stock quantity it will be included in the query results. What i would need is the query below but that one is broken and returns no results at all.

My desired query (notice the .$. in the 4th line):

$stockedProducts = ProductsDetails::query()
->where('seller_uid', '=', $seller->UID)
->where('locations.location', '=', $locationUid)
->where('locations.$.quantity_stock', '=', 0);

But this doesn't work. It works when i try to update the data but not in the initial query.

I need a way to tell the query that once it found the proper location in line 3 to make sure that the stock for only that location must be 0.

How could i accomplish this like i want?

Thank you so much for your assistance.

Hello @nicolasvahidzein, you can use the $elemMatch operator.

$stockedProducts = ProductsDetails::query()
    ->where('seller_uid', '=', $seller->UID)
    ->where('locations', 'elemmatch', [
        'location' => $locationUid,
        'quantity_stock' => 0,
    ]);
