odata - 使用 Breezejs 发布批量请求

Question

我一直在尝试使用 Breezejs 和 WebAPI OData Controller 发布一个实体。
配置如下:

config.Routes.MapODataRoute(
routeName: "odata",
routePrefix: "odata",
model: model,
batchHandler: new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));

模型非常直接:

public class ServiceMetadata
{
    public int ServiceMetadataId { get; set; }
    public string ServiceName { get; set; }
    public string Description { get; set; }
    public ObjectState? State { get; set; }
    public DateTime? LastUpdated { get; set; }
}

并且是通过默认映射的:

ODataModelBuilder modelBuilder = new ODataConventionModelBuilder();

客户端 也非常简单，使用 AngularJs 并部分来自 Todo 示例:http://www.breezejs.com/samples/todo-angular

breeze.config.initializeAdapterInstance("modelLibrary", "backingStore", true);
var serviceName = 'http://localhost:8081/odata/';
breeze.config.initializeAdapterInstances({ dataService: "OData" });
var manager = new breeze.EntityManager(serviceName);
manager.enableSaveQueuing(true);

实际发布是使用默认的 createEntity() 方法完成的:

function createServiceMetadata(initialValues) {
    return manager.createEntity('ServiceMetadata', initialValues);
}

整个事情看起来像:

 serviceMetadatas.createServiceMetadata({
     ServiceName: $scope.newServiceName,
     Description: $scope.newServiceDescription
 });

 serviceMetadatas.saveChanges();

但是，请求没有被传输到正确的 Controller (从 EntitySetController 继承的 ServiceMetadatasController)，或与此相关的任何其他 Controller 。
HTTP 请求如下所示:

知道黑客是怎么回事吗？B.T.W GET 请求效果很好。

附言在看了几个演示之后，我认为考虑到 WebApi 和 OData，使用 BreezeJS 会很直接。
我必须说，配置此 JS 库远并不容易。我希望它会变得难以设置但易于使用。

谢谢。

@UPDATE 查看 Javier 的精彩回答!!

在挖掘 allllot 上的 breeze 代码后，我开始意识到问题出在 breezejs 的 createChangeRequests() 深处，就在这里:

request.requestUri = entity.entityType.defaultResourceName;

由于某些原因，defaultResouceName 完全忽略了该实体的路径。长话短说，下面是一个黑客要解决的问题:

manager.metadataStore.getEntityType(ENTITY_TYPE).setProperties({defaultResourceName: THE_MISSING_PART_FROM_THE_URL + ENTITY_TYPE});
manager.createEntity(ENTITY_TYPE, values);

不是很好，但仍然有效!

Answer 1

新的答案是 .. 使用 webApiOData 数据服务而不是“OData”:

breeze.config.initializeAdapterInstances({ 
  dataService : 'webApiOData'
});
