undefined method where function in laravel-CodePudding

I've been trying to filter out the product. If their category is popular, it will be retrieved. However, it's an error if I use a where in my controller. I think there's a wrong in my query?

Error: Call to undefined method Google\Cloud\Firestore\QuerySnapshot::where()

Language: PHP Framework: Laravel 9 Database: Firebase, firestore

What i have tried so far:

Cloud Firestore QuerySnapshot Where function field not supported [still returning the same error]
Fatal error: Uncaught Error: Call to undefined method Google\Cloud\Storage\StorageClient::collection() [not applicable to mine]

controller:

$product = app('firebase.firestore')->database()->collection('Products')->documents();
        $query1 = $product->where('category', isEqual: "popular");
        $popular = $query1->documents();
        return view('admin.product', compact('product', 'popular'));

CodePudding user response：

Remove ->documents() from the $product as you're trying to use the where method on the result and not on the query builder which is why where is not available. Also, then you need to introduce another variable to store the query builder so that you can also get the products.

Updated code:

$query = app('firebase.firestore')->database()->collection('Products');

$product = $query->documents();

$popular = $query->where('category', isEqual: "popular")->documents();

return view('admin.product', compact('product', 'popular'));
