我在EF 4.0中定义了一个基于视图的实体.该视图覆盖了一个包含大约1800万行数据的表.我已选择实体的4个确定性属性作为此实体的复合实体键.我通过OData WCF数据服务公开了对包含此视图的模型的访问.WCF数据服务设置为限制结果

config.SetEntitySetPageSize("*", 100)

当我针对此视图进行基本查询时:

var fcbs = this.iBenchmarkCostContext.FtCostBenchmarks.ToArray();

这是我在分析工具中看到的查询:

SELECT TOP (100) [Extent1].[MonthBeginDt]                     AS [MonthBeginDt],
                 [Extent1].[dmCostBenchmarkKey]               AS [dmCostBenchmarkKey],
                 [Extent1].[dmProductKey]                     AS [dmProductKey],
                 [Extent1].[IsImputedFlg]                     AS [IsImputedFlg],
                 [Extent1].[ProjectedCopayPerRxAmt]           AS [ProjectedCopayPerRxAmt],
                 [Extent1].[ProjectedPricePerQtyAmt]          AS [ProjectedPricePerQtyAmt],
                 [Extent1].[ProjectedQtyPerRxQty]             AS [ProjectedQtyPerRxQty],
                 [Extent1].[ProjectedRxCnt]                   AS [ProjectedRxCnt],
                 [Extent1].[AvgPriceRxAvgPriceQtyDenominator] AS [AvgPriceRxAvgPriceQtyDenominator],
                 [Extent1].[AvgQtyDenominator]                AS [AvgQtyDenominator],
                 [Extent1].[AvgCopayDenominator]              AS [AvgCopayDenominator],
                 [Extent1].[ProjectedTotalCostAmt]            AS [ProjectedTotalCostAmt],
                 [Extent1].[AllowedRxCnt]                     AS [AllowedRxCnt],
                 [Extent1].[CopayRxCnt]                       AS [CopayRxCnt],
                 [Extent1].[TotalAllowedAmt]                  AS [TotalAllowedAmt],
                 [Extent1].[TotalCopayAmt]                    AS [TotalCopayAmt],
                 [Extent1].[TotalCostPerUnitAmt]              AS [TotalCostPerUnitAmt],
                 [Extent1].[TotalUnitQty]                     AS [TotalUnitQty],
                 [Extent1].[RC]                               AS [RC]
FROM   (SELECT [ftCostBenchmark].[MonthBeginDt]                     AS [MonthBeginDt],
               [ftCostBenchmark].[dmCostBenchmarkKey]               AS [dmCostBenchmarkKey],
               [ftCostBenchmark].[dmProductKey] …

我有一个Angular Dart页面,我需要在屏幕上为集合中的每个项目创建一个组件.这些项目是自定义模型对象:

    class CohortDataSourceAssay{
      String name;
      String displayName;
      bool selected;
      List<String> platforms = new List<String>();

      CohortDataSourceAssay();
    }

我有一个父页面,我想为上面类的集合中的每个元素创建一个模板:

    <data-source-assay *ngFor="let assay of dataSource.assays"></data-source-assay>

以下是数据源分析组件的标记:

    <div class="dataSourceAssay">
        <material-checkbox [(ngModel)]="assay.selected" (ngModelChange)="onCbxChange($event)">{{assay.displayName}}</material-checkbox>
        <material-dropdown-select class="selectStyle"
                                  [disabled]="!assay.selected"
                                  [buttonText]="platformLabel"
                                  [selection]="assaySequencingPlatforms"
                                  [options]="sequencingPlatforms"
                                  [itemRenderer]="itemRenderer">
        </material-dropdown-select>
    </div>

这适用于在dataSource.assays中为每个测定元件加载块,但是测定块似乎不能获得测定模型对象.它似乎是空的.我如何传递它？
