Which query is better to use (and why)?

Question

Laravel

Request 1

$file=Auth::user()
                              ->products()
                              ->where('slug',$product_slug)
                              ->firstOrFail()
                              ->files()
                              ->where('slug', $file_slug)
                              ->firstOrFail();

Request 2

$file=File::where('slug', $file_slug)
                               ->whereHas('product', function ($query) use ($product_slug) {
                         $query->where('products.user_id', '=', Auth::id());
                         $query->where('products.slug', '=', $product_slug);
                     })
                               ->firstOrFail();

Answer 1

of the 2 indicated, I am for 1 because whereHas is very slow, and there is no saving in the number of queries in option 2, but as for me it is better to use the hasManyThrough connection here
