私はそよ風/ノックアウトに非常に慣れていませんが、必要なことを 99% 達成しています。私はホット タオル テンプレートを使用しており、そよ風を介してアイテムのリストを正常に取得しています。エンティティ (ITBAL) は、データベースの最初の Entity Framework エンティティです。Fiddler に返される JSON を見ると、正しいデータが表示されます。問題は、data.results のすべてのプロパティが依存オブザーバブルであり、生の値自体ではないことです。

data.results 配列を表示しようとするカスタム グリッド コントロールがあります。オブザーバブルを想定していないため、値の代わりに単に「関数依存オブザーバブル」を表示しています。

オブジェクトをアンラップしようとしましたが、循環参照エラーが発生し続けます。ITBAL は何にも関連付けられていないため、その理由はわかりません。

Fiddler が報告するデータは次のとおりです。

私のコントローラー：

    [BreezeController]
public class ItemInquiryController : ApiController
{

    readonly EFContextProvider<AplusEntities> _contextProvider = new EFContextProvider<AplusEntities>();

    [System.Web.Http.HttpGet]
    public string Metadata()
    {
        return _contextProvider.Metadata();
    }

    [HttpGet]
    public IQueryable<ITBAL> ItemBalances(string itemNumber, string warehouse)
    {
        return _contextProvider.Context.ITBALs.Where(i => i.IBITNO == itemNumber && i.IBWHID == warehouse)
                               .OrderBy(i => i.IBWHID)
                               .ThenBy(i => i.IBITNO);


    }

}

ビューモデルの関連部分:

        var manager = new breeze.EntityManager("api/ItemInquiry");
    var store = manager.metadataStore;

    var itbalInitializer = function (itbal) {
        itbal.CompositeKey = ko.computed(function () {
            return itbal.IBITNO() + itbal.IBWHID();
        });
    };

    store.registerEntityTypeCtor("ITBAL", null, itbalInitializer);
    var index = "0" + (args.pageNum * args.pageSize);

    var query = new breeze.EntityQuery("ItemBalances")
        .withParameters({ itemNumber: "A100", warehouse: "1" })
        .take(args.pageSize);

    if (index > 0) {
        query = query.skip(index);
    }

    manager.executeQuery(query).then(function (data) {

        vm.itbals.removeAll();

        var itbals = data.results;//[0].Data;
        itbals.forEach(function (itbal) {
            vm.itbals.push(itbal);
        });

        vm.totalRecords(1);
        itemBalancesGrid.mergeData(vm.itbals(), args.pageNum, parseInt(vm.totalRecords()));

    }).fail(function (e) {
        logger.log(e, null, loggerSource, true, 'error');
    });

かなり単純なものが欠けているに違いないと思いますが、それは私を逃れています。

更新: ApiController から BreezeController 属性を削除したところ、正しく機能しました。
