Magento 2：無法更新產品庫存（數量）

Question

我創建了一個控制台命令，該命令循環遍歷產品並嘗試更新庫存數量。 我完成索引后（從命令行）重新索引，但它從未更改。 我在一個已經安裝了PHP7的無聊的盒子上，並且當我使用save（）方法時以前遇到了“分段錯誤”，因此我不得不在管理部分中將索引器更改為“按計划更新”，然后運行從命令行手動建立索引器，但是我仍然沒有看到產品數量的更新。 為了使產品正確保存，我還需要做其他事情嗎？

Answer 1

嘗試這樣的代碼：

$product->setStockData(['qty' => $qty, 'is_in_stock' => 1]);
$product->setQuantityAndStockStatus(['qty' => $qty, 'is_in_stock' => 1]);

它為我工作。 setQty不起作用，因為數量沒有直接存儲在產品EAV表中，它使用單獨的stock_item表
