微風複雜類型數據屬性顯示無數據

正如您在下面看到的，我在Make實體上添加了一個新的名稱數據屬性作爲複雜類型。複雜類型顯示在初始化函數的底部。

在調用web api並返回結果後，我在make結果上看到新的數據屬性，但沒有這個新名稱的數據。如下所示：

我缺少什麼？

謝謝...

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數據，您將需要更改「jsonResultsAdapter」代碼。

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

不知道我理解您的評論。 – 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

未定義型示出了具有陣列數據[1]，而複雜的類型顯示數據具有空值，並且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「：{}}]}
