Question

我使用Breeze Edmunds作为例子。

如下所示，我在Make实体上添加了一个新的名称数据属性作为复杂类型。复杂类型显示在初始化函数的底部。

在调用web api并返回结果后，我在make结果中看到了新的data属性，但是没有这个新名称的数据。如下所示：

Array[61]

_backingStore: Object
entityAspect: ctor
id: (...)
modelLinks: (...)

我缺少什么？

...谢谢

    metadataStore.addEntityType({
        shortName: "Make",
        namespace: "Edmunds",
        dataProperties: {
            id:         { dataType: DT.Int64, isPartOfKey: true },
            name: { dataType: DT.String },
            names: { dataType: DT.ComplexType, complexTypeName: "Names:#Edmunds", isScalar: true },
            niceName:   { dataType: DT.String },
            modelLinks: { dataType: DT.Undefined }
        },
        navigationProperties: {
            models: {
                entityTypeName:  "Model:#Edmunds", isScalar: false,
                associationName: "Make_Models"
            }
        }
    });

    metadataStore.addEntityType({
        shortName: "Names",
        namespace: "Edmunds",
        isComplexType: true,
        dataProperties: {
            name: { dataType: DT.String, isNullable: false }
        }
    });

Answer 1

如果您更改此示例中的元数据，则需要更改＆＃39; jsonResultsAdapter＆＃39;代码也是如此。

Answer 2

I added the complex type as well as the undefined type and as you can there is no data resturned in the complexy type but the undefined type returned fine.

Model Changes

    function initialize(metadataStore) {
            metadataStore.addEntityType({
                shortName: "Make",
                namespace: "Edmunds",
                dataProperties: {
                    id: { dataType: DT.Int64, isPartOfKey: true },
                    modelList: { dataType: DT.ComplexType, complexTypeName: "ModelList:#Edmunds", isScalar: true },
                    name: { dataType: DT.String },
                    niceName:   { dataType: DT.String },
                    modelLinks: { dataType: DT.Undefined }
                }
                //navigationProperties: {
                //    models: {
                //        entityTypeName:  "Model:#Edmunds", isScalar: false,
                //        associationName: "Make_Models"
                //    }
                //}
            });


This is my jsonResultsAdapter code

visitNode: function (node, parseContext, nodeContext) {
            // Make parser
            if (node.id && node.models) {
                // move 'node.models' links so 'models' can be empty array
                modelList = node.models;
                node.modelLinks = node.models;
                //node.models = [];
                return { entityType: "Make"  }
            }

            // Model parser
            else if (node.id && node.makeId) {
                // move 'node.make' link so 'make' can be null reference
                node.makeLink = node.make;
                node.make = null;

                // flatten styles and sizes as comma-separated strings
                var styles = node.categories && node.categories["Vehicle Style"];
                node.vehicleStyles = styles && styles.join(", ");
                var sizes = node.categories && node.categories["Vehicle Size"];
                node.vehicleSizes = sizes && sizes.join(", ");

                return { entityType: "Model" };
            }


This is the results

未定义类型显示数组[1]的数据，而复杂类型显示数据具有空值，并且是proto._setCtor.proto

This is the JSON

{＆＃34; makeHolder＆＃34;：[{＆＃34; ID＆＃34;：200347864＆＃34;模式＆＃34;：[{＆＃34;连结＆＃34;：＆＃34; / API /载体/ AM-一般/悍马＆＃34;＆＃34; ID＆＃34;：＆＃34; AM_General_Hummer＆＃34;＆＃34;名称＆＃34;：＆＃34;悍马＆＃34;} ]，＆＃34;名称＆＃34;：＆＃34; AM General＆＃34;，＆＃34; niceName＆＃34;：＆＃34; amgeneral＆＃34;，＆＃34; manufacturer＆＃34;：null，＆＃34; attributeGroups＆＃34;：{}}]}

Breeze复杂类型数据属性显示无数据
