带 select 字段的实体查找给出错误消息

Question

当运行以下代码时：

 <entity-find entity-name="mantle.order.OrderHeaderPartFacilityStatus" list="orderPartList">
                <econdition field-name="facilityId" from = "facilityId"/>
                <econdition field-name="statusId" operator="in" value="OrderPlaced,"/>

                <!-- <select-field field-name="orderId, "/> -->
                <!-- <select-field field-name="orderName"/> -->
                <!-- <select-field field-name="placedDate"/> -->
                <!-- <select-field field-name="grandTotal"/> -->
                <!-- <select-field field-name="orderPartSeqId"/> -->
                <!-- <select-field field-name="facilityId"/> -->
                <!-- <select-field field-name="facilityName"/> -->
                <!-- <select-field field-name="partStatusId"/> -->
                <!-- <order-by field-name="orderPartSeqId"/> -->
        </entity-find>

我得到了：

 "orderPartList": [
    {
        "enteredByPartyId": null,
        "salesChannelEnumId": null,
        "recurrenceInfoId": null,

        "systemMessageRemoteId": null,
        "maySplit": null,
        "externalId": null,
        "parentPartSeqId": null,
        "facilityName": "\u5357\u5185\u73af\u8f66\u95f4",
        "orderId": "FOJohndoePassat",
        "vendorPartyId": null,
        "shipAfterDate": null,
        "currencyUomId": null,
        "orderName": "John_doe order 1",
        "grandTotal": 5.1E+2,
        "partStatusId": "OrderOpen",
        "partName": "\u7b2c\u4e00\u90e8\u5206 John doe",
        "statusDescription": "Placed"
    }
],

但是当我取消注释select-field标签时，如下：

 <entity-find entity-name="mantle.order.OrderHeaderPartFacilityStatus" list="orderPartList">
                <econdition field-name="facilityId" from = "facilityId"/>
                <econdition field-name="statusId" operator="in" value="OrderPlaced,"/>

                <select-field field-name="orderId, "/>
                <!-- <select-field field-name="orderName"/> -->
                <!-- <select-field field-name="placedDate"/> -->
                <!-- <select-field field-name="grandTotal"/> -->
                <!-- <select-field field-name="orderPartSeqId"/> -->
                <!-- <select-field field-name="facilityId"/> -->
                <!-- <select-field field-name="facilityName"/> -->
                <!-- <select-field field-name="partStatusId"/> -->
                <!-- <order-by field-name="orderPartSeqId"/> -->
        </entity-find>

然后我收到以下错误消息，这可能表明 select sql 不工作：

{"errorCode":500,"errors":"java.lang.IllegalArgumentException: Maps with null keys can't be converted to JSON"}

有什么问题吗？我正在使用自定义数据运行ing MoquiDemo-2.0.0。这可能是一个错误或什么？有人知道吗？

Answer 1

field-name "orderId, " 无效。逗号用于分隔多个字段名称，因此它会将其转换为 "orderId" 和 "" 的列表，空字符串不是有效的字段名称。

类似地，在您对 statusId 的 econdition 中，@value 属性末尾有一个逗号。如果您尝试包含具有空 statusId 的记录，请使用 econdition.@or-null 属性。如果这不是您想要的，为了更有效的查询，请去掉逗号并使用等号运算符（这是默认值，因此您不需要运算符属性）。

总的来说这段代码很草率。 Moqui 试图容忍有趣的事情并尽力而为，但无效的字段名称等仍然无效，你会得到错误。您可能在服务器端日志中也有更多错误或警告，这通常是检查是否有问题的第一个地方。
