如果实体是品牌 new/temporary，如何将实体发送到全局操作输入参数？

Question

我认为这个问题与此处链接的问题不同：

我有一个接受 ClubOfficer 实体作为必需输入参数的全局操作。这是我的代码生成的有效负载示例：

{
    "ClubOfficer":{
        "_ti_club_officer_code_value":"6efab90f-7d2b-e811-a957-000d3a34a108",
        "ti_club_id":{
            "accountid":"cbf646cb-a232-e811-a959-000d3a34a0aa"
        },
        "ti_member":{
            "contactid":"e318472c-c732-e811-a959-000d3a34ae50"
        },
        "ti_start_date":"2018-07-01T00:00:00Z",
        "ti_end_date":"2018-12-31T23:59:59Z"
    },
    "Term":"Current"
}

但是，甚至在调用该操作之前，它就失败并显示错误：

{
    "error": {
        "code": "0x0",
        "message": "CRM do not support direct update of Entity Reference properties, Use Navigation properties instead.",
        "innererror": {
            "message": "CRM do not support direct update of Entity Reference properties, Use Navigation properties instead.",

        }
    }
}

ClubOfficer 不是现有实体，但我希望 Action 将其视为 ClubOfficer 临时实体，以便我可以利用实体属性的 "type safety"。那可能吗？或者我是否必须将 ClubOfficer 作为字符串参数传递，然后对 JSON 字符串进行操作？这个错误是什么意思，我该如何解决？

Answer 1

很遗憾，这是不可能的。您没有将整个实体传递给操作，您只是传递了实体引用，它只是实体的名称及其 ID。所以你无论如何都不能传递额外的值。

执行此操作的正确方法是为每个输入创建额外的输入参数。这样它们将是强类型的。另一种选择是传递一个 JSON 字符串有效负载，您使用自定义 activity.

解析该字符串有效负载

希望对您有所帮助！
