Inserting and updating records from 3 tables in laravel - laravel

Question

I am storing records for my product transfer app using 3 tables in single action. Transferhistories, Warehouse1StockSummaries and Warehouse2StockSummaries.
storing records to trasnferinghistories is ok, and also the increment method I declare to Warehouse2StockSummaries is also working fine except for Warehouse1StockSummaries.
here's my store function,
public function store(Request $request)
{
$input = $request->all();
$items = [];
for($i=0; $i<= count($input['product_id']); $i++) {
// if(empty($input['stock_in_qty'][$i]) || !is_numeric($input['stock_in_qty'][$i])) continue;
if(!isset($input['qty_in'][$i]) || !is_numeric($input['qty_in'][$i])) continue;
$acceptItem = [
'product_id' => $input['product_id'][$i],
'transfer_qty' => $input['qty_out'][$i],
'user_id' => $input['user_id'][$i]
];
array_push($items, Transferhistories::create($acceptItem));
// dd($input);
//update warehouse 1 summary
$warehouse1summary = Warehouse1StockSummaries::firstOrCreate(
['product_id' => $input['product_id'][$i]],
['qty_in' => $input['qty_in'][$i],
'qty_out' => $input['qty_out'][$i]
]);
if (!$warehouse1summary->wasRecentlyCreated) {
$warehouse1summary->increment('qty_out', $input['qty_out'][$i]);
}
//update warehouse 2 summary
$stock2Summary = Warehouse2StockSummaries::firstOrCreate(
['product_id' => $input['product_id'][$i]],
['qty_in' => $input['qty_out'][$i],'qty_out' => null]);
if (!$stock2Summary->wasRecentlyCreated) {
$stock2Summary->increment('qty_in', $input['qty_in'][$i]);
}
}
return redirect()->route('transferHistory.index');
}
updating warehouse 1 summary is not doing what it should be.
any suggestion master? thank you so much in advance!

Answer 1

According to laravel, firstOrCreate does not save the value, so after you do:
$warehouse1summary = Warehouse1StockSummaries::updateOrCreate(
['product_id' => $input['product_id'][$i]],
['qty_in' => $input['qty_in'][$i],
'qty_out' => $input['qty_out'][$i]
]);
Edit
The method firstOrNew will return the first or a instance of the Model.
So what you wanna do is this:
$warehouse1summary = Warehouse1StockSummaries::firstOrNew(
['product_id' => $input['product_id'][$i]],
['qty_in' => $input['qty_in'][$i],
'qty_out' => $input['qty_out'][$i]
]);
if(isset($warehouse1summary->created_at)){
$warehouse1summary->qty_out = $warehouse1summary->qty_out + $input['qty_out'][$i];
}
$warehouse1summary->save();
