微风复杂类型数据属性显示无数据

正如您在下面看到的，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结果上看到新的数据属性，但没有这个新名称的数据。如下所示：

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 } 
     } 
    });

如果此示例中修改元数据，您将需要更改“jsonResultsAdapter”代码。

我做了以下更改，影响 – user3853158 2014-09-02 13:03:45

不知道我理解您的评论。 – 2014-09-02 20:01:44

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

未定义型示出了具有阵列数据[1]，而复杂的类型显示数据具有空值，并且proto._setCtor.proto

{ “makeHolder”：[{ “ID”： 200347864，“models”：[{“link”：“/ api/vehicle/am-general/hummer”，“id”：“AM_General_Hummer”，“name”：“Hummer”}]，“name” “，”niceName“：”amgeneral“，”manufacturer“：null，”attributeGroups“：{}}]}
