当我发布一个没有填充集合的 ShakeoutDocument 时，OData Serializer 理解 JSON 并填充 ODataActionParameters 正确。
但是，当我将子记录添加到 ShakeoutDocument 的 集合属性中时...Odata Controller 的 ODataActionParameters 参数为空.我已将其缩小到 OData EDM 模型配置。
- 我如何正确地将集合属性(如下)“特征化”到 EDM 模型配置
类看起来像:
藏品是细节和印章(下)
public class ShakeoutDocument : Document
{
public IObjectState ObjectState { get; set; } //<-- This "registers" just fine?
public int ShakeoutId { get; set; }
public string SchedulingBatch { get; set; }
public int? ProductId { get; set; }
public decimal? Gravity { get; set; }
public decimal? Temperature { get; set; }
public decimal? SedimentAndWater { get; set; }
public DateTime? BatchEndDate { get; set; }
public DateTime? SampleWorkedDate { get; set; }
public string Witness { get; set; }
public string Notes { get; set; }
public List<ShakeoutDetail> Details { get; set; } //<-- How do I "register" this?
public List<ShakeoutSeal> Seals { get; set; } //<-- How do I "register" this?
}
我当前的 EDM 配置如下所示:
我尝试了定义的各种方法 HERE .奇怪的是...IObjectState 注册得很好。
private static IEdmModel GetEdmModel()
{
var modelBuilder = new ODataConventionModelBuilder();
modelBuilder.Namespace = "Pulse";
modelBuilder.ContainerName = "PulseContainer";
// -------------------
// ENTITY SETS: Normal
modelBuilder.EntitySet<tblDbcCommunications>("Communication");
modelBuilder.EntitySet<tblDbcItems>("Item");
modelBuilder.EntitySet<Meter>("Meter");
modelBuilder.EntitySet<Product>("Products");
modelBuilder.EntitySet<WarehouseMeter>("WarehouseMeters");
modelBuilder.EntitySet<tblDbcCircuitOwner>("tblDbcCircuitOwner");
modelBuilder.EntitySet<ShakeoutDetail>("ShakeoutDetails");
modelBuilder.EntitySet<ShakeoutSeal>("ShakeoutSeals");
// --------------------
// ENTITY SETS: Complicated
ConfigureEntitySet(modelBuilder, modelBuilder.EntitySet<ShakeoutDocument>("ShakeoutDocuments"));
// ------------
// KEY BINDINGS: Non-Entity
//
// - This area is for DTO's (there is no EF Configuration for these)
modelBuilder.EntityType<WarehouseMeter>().HasKey(x => x.METER_ID);
// -----------------
// UNBOUND FUNCTIONS
// - Action = Post
// - Function = Get
//----
// ShakeoutDocument
var createShakeoutDocument = modelBuilder.Action("CreateShakeoutDocument").ReturnsFromEntitySet<ShakeoutDocument>("ShakeoutDocument");
createShakeoutDocument.CollectionParameter<int>("identities");
var deleteShakeoutDocument = modelBuilder.Action("DeleteShakeoutDocument").ReturnsFromEntitySet<ShakeoutDocument>("ShakeoutDocument");
deleteShakeoutDocument.Parameter<int>("key");
var getShakeoutDocument = modelBuilder.Function("GetShakeoutDocument").ReturnsFromEntitySet<ShakeoutDocument>("ShakeoutDocument");
getShakeoutDocument.Parameter<int>("key");
var saveShakeoutDocument = modelBuilder.Action("SaveShakeoutDocument").ReturnsFromEntitySet<ShakeoutDocument>("ShakeoutDocument");
saveShakeoutDocument.Parameter<ShakeoutDocument>("document");
//----
// ShakeoutDetail
var saveShakeoutDetail = modelBuilder.Action("SaveShakeoutDetail").ReturnsFromEntitySet<ShakeoutDetail>("ShakeoutDetail");
saveShakeoutDetail.Parameter<ShakeoutDetail>("detail");
//----
// ShakeoutSeal
var saveShakeoutSeal = modelBuilder.Action("SaveShakeoutSeal").ReturnsFromEntitySet<ShakeoutSeal>("ShakeoutSeal");
saveShakeoutSeal.Parameter<ShakeoutSeal>("seal");
//----
// Product
var listProduct = modelBuilder.Function("ListProducts").ReturnsCollectionFromEntitySet<Product>("Product");
//----
// WarehouseMeter
var findPulseMeter = modelBuilder.Function("FindWarehouseMeter").ReturnsCollectionFromEntitySet<WarehouseMeter>("WarehouseMeter");
findPulseMeter.Parameter<string>("search");
return modelBuilder.GetEdmModel();
}
private static EntitySetConfiguration<ShakeoutDocument> ConfigureEntitySet(ODataConventionModelBuilder modelBuilder, EntitySetConfiguration<ShakeoutDocument> configuration)
{
// ---------------------
// Collection Properties
// FAILS: Meaning, the collection is not serialized & returned
//var details = configuration.EntityType.CollectionProperty(x => x.Details);
//var seals = configuration.EntityType.CollectionProperty(x => x.Seals);
// FAILS: Meaning, the collection is not serialized & returned
//configuration.HasManyBinding(x => x.Details, "ShakeoutDetail");
//configuration.HasManyBinding(x => x.Seals, "ShakeoutSeal");
// ------------------
// Complex Properties
configuration.EntityType.ComplexProperty(x => x.ObjectState);
// IObjectState
var objectState = modelBuilder.ComplexType<IObjectState>();
objectState.CollectionProperty(x => x.Events);
// Object State
var newObjectState = modelBuilder.ComplexType<New>();
newObjectState.DerivesFrom<IObjectState>();
var submittedObjectState = modelBuilder.ComplexType<Submitted>();
submittedObjectState.DerivesFrom<IObjectState>();
// Object State Event
var isNewObjectStateEvent = modelBuilder.ComplexType<IsNew>();
isNewObjectStateEvent.DerivesFrom<IObjectStateEvent>();
var isSubmittedObjectStateEvent = modelBuilder.ComplexType<IsSubmitted>();
isSubmittedObjectStateEvent.DerivesFrom<IObjectStateEvent>();
return configuration;
}
发送此 JSON 有效:
如果我 SEND 这个 JSON 没有填充 Details & Seals 集合..它会正确序列化。
如果我填充 Details & Seals 集合...参数为 NULL。

}
}
接收失败:
这显示了从服务发送回客户端的对象和客户端收到的 JSON。
未绑定(bind)函数看起来像:
为了完整起见，我包括了这个......
[HttpPost]
[ODataRoute("SaveShakeoutDocument")]
public IHttpActionResult SaveDocument(ODataActionParameters parameters)
{
var provider = Application.ShakeoutDocumentProvider;
var document = null as ShakeoutDocument;
try
{
document = provider.Get(key);
}
catch (Exception ex)
{
LogException(ex);
throw;
}
return Ok(document);
}
更新 1:
$MetaData 似乎了解集合类型...
<EntityType Name="ShakeoutDocument" BaseType="Pulse.Document">
<Property Name="ObjectState" Type="Pulse.IObjectState" Nullable="false"/>
<Property Name="ShakeoutId" Type="Edm.Int32" Nullable="false"/>
<Property Name="SchedulingBatch" Type="Edm.String"/>
<Property Name="ProductId" Type="Edm.Int32"/>
<Property Name="Gravity" Type="Edm.Decimal"/>
<Property Name="Temperature" Type="Edm.Decimal"/>
<Property Name="SedimentAndWater" Type="Edm.Decimal"/>
<Property Name="BatchEndDate" Type="Edm.DateTimeOffset"/>

<Property Name="Notes" Type="Edm.String"/>
<NavigationProperty Name="Details" Type="Collection(Pulse.ShakeoutDetail)"/>
<NavigationProperty Name="Seals" Type="Collection(Pulse.ShakeoutSeal)"/>
</EntityType>
更新 2:
我刚刚注意到...ShakeoutDetails 和 ShakeoutDetail 的 NavigationPropertyBinding 为“Meter”...ShakeoutDocument 中不存在(并且永远不会包含在内，因为这是模型而不是实体)。

最佳答案
根据您的最新更新，我认为导航属性绑定(bind)的问题很有趣。
它没有解析 Meter，你应该看看 https://odata.github.io/WebApi/13-03-NavigationPropertyBindingWithComplexType/ (如果需要，还可以查看 Transient Actions)
关于c# - OData 无法识别我的集合属性，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56115354/
