使用数据存储区命令行工具创建嵌入式实体 [英] Creating embedded entities with the datastore command line tool

问题描述

我正在尝试使用Google云数据存储区命令行界面来创建嵌入式实体的数组.我已经弄清楚了如何创建嵌入的实体值，如下所示:

I'm trying to use the Google cloud datastore command line interface to create arrays of embedded entities. I've figured out how to create an embedded entity value as follows:

{
    "properties": {
        "age": {
            "integerValue": "5"
        },
        "height": {
            "integerValue": "6"
        }
    }
}

以及如何创建数组值，如下所示:

and how to create an array value as follows:

{
    "values": [
        {
            "stringValue": "one"
        },
        {
            "stringValue": "two"
        }
    ]
}

但是我还没有弄清楚如何向数组添加嵌入值.例如:

But I haven't figured out how to add an embedded value to an array. For example:

{
    "values": [
        {
            "stringValue": "one"
        },
        {
            "stringValue": "two"
        },
        {
            "embeddedEntityValue": {
                "properties": {
                    "age": {
                        "integerValue": "5"
                    },
                    "height": {
                        "integerValue": "6"
                    }
                }
            }
        }
    ]
}

给出错误: 此数组中的一个或多个值看起来不正确.如果包含值，请确保它们是JSON格式的数据存储区数组值."

gives the error: "One or more values in this array doesn't look right. If you include values, make sure they are Datastore array values in JSON format."

推荐答案

我相信embeddedEntityValue应该更改为entityValue.下面是显示带有两个嵌入式实体的Array字段的示例:

I believe embeddedEntityValue should be changed to entityValue. Below is an example that shows an Array field with two embedded entities:

{
  "values": [
    {
      "entityValue": {
        "properties": {
          "areaCode": {
            "stringValue": "40"
          },
          "countryCode": {
            "stringValue": "91"
          },
          "subscriberNumber": {
            "stringValue": "2722 5858"
          }
        }
      }
    },
    {
      "entityValue": {
        "properties": {
          "countryCode": {
            "stringValue": "91"
          },
          "subscriberNumber": {
            "stringValue": "6666 0000"
          },
          "areaCode": {
            "stringValue": "80"
          }
        }
      }
    }
  ]
}
