更新arangodb中的內部對象

Question

我有一個存儲在arangodb中的對象，該對象具有其他內部對象，我的當前用例要求僅更新元素之一。

儲存物件

{
  "status": "Active",
  "physicalCode": "99999",
  "postalCode": "999999",
  "tradingCurrency": "USD",
  "taxRate": "14",
  "priceVatInclusive": "No",
  "type": "eCommerce",
  "name": "John and Sons inc",
  "description": "John and Sons inc",
  "createdDate": "2015-05-25T11:04:14+0200",
  "modifiedDate": "2015-05-25T11:04:14+0200",
  "physicalAddress": "Corner moon and space 9 station",
  "postalAddress": "PO Box 44757553",
  "physicalCountry": "Mars Sector 9",
  "postalCountry": "Mars Sector 9",
  "createdBy": "john.doe",
  "modifiedBy": "john.doe",
  "users": [
    {
      "id": "577458630580",
      "username": "john.doe"
    }
  ],
  "products": [
    {
      "sellingPrice": "95.00",
      "inStock": "10",
      "name": "School Shirt Green",
      "code": "SKITO2939999995",
      "warehouseId": "723468998682"
    },
    {
      "sellingPrice": "95.00",
      "inStock": "5",
      "name": "School Shirt Red",
      "code": "SKITO245454949495",
      "warehouseId": "723468998682"
    },
    {
      "sellingPrice": "95.00",
      "inStock": "10",
      "discount": "5%",
      "name": "School Shirt Blue",
      "code": "SKITO293949495",
      "warehouseId": "723468998682"
    }
  ]
}

我只想更改產品庫存值之一

{
  "sellingPrice": "95.00",
  "inStock": "10",
  "discount": "5%",
  "name": "School Shirt Blue",
  "code": "SKITO293949495",
  "warehouseId": "723468998682"
}

就像更新商店產品庫存減去1（商店ID = x）一樣，可以達到這種效果

FOR store IN stores
    FILTER store._key == "837108415472"
    FOR product IN store.products 
        FILTER product.code == "SKITO293949495"
    UPDATE product WITH { inStock: (product.inStock - 1) } IN store.products

除此之外，將產品作為單獨的文檔存儲在collection store_products中可能是有意義的。 我相信NOSQL是減少文檔大小的最佳方法。

找到答案

這是arangodb-aql更新單個對象在嵌入式數組中 ，還有arangodb-aql更新對象內部的字段

但是，我認為最好是保留單獨的文檔，而是在檢索時使用聯接。 輕松更新
