Question

我在复杂类型中添加关系时遇到以下错误。我该如何解决这个问题。我感到愤怒并且读到它与OData V3有关但在OData V4中没有。

复杂类型＆＃39; Microsoft.OneIM.ActiveIncident.Contracts.IncidentImpact＆＃39;指实体类型＆＃39; Microsoft.OneIM.ActiveIncident.Contracts.ImpactedService＆＃39;通过物业＆＃39; ImpactedServices＆＃39;。

at System.Web.OData.Builder.ODataConventionModelBuilder.MapComplexType（ComplexTypeConfiguration complexType）在System.Web.OData.Builder.ODataConventionModelBuilder.MapType（StructuralTypeConfiguration edmType）在System.Web.OData.Builder.ODataConventionModelBuilder.AddComplexType（Type type）在System.Web.OData.Builder.ODataConventionModelBuilder.ReconfigureEntityTypesAsComplexType（EntityTypeConfiguration [] misconfiguredEntityTypes）在System.Web.OData.Builder.ODataConventionModelBuilder.RediscoverComplexTypes（）在System.Web.OData.Builder.ODataConventionModelBuilder.GetEdmModel（）在c：\ OneIM \ EngSys \ OneIM \ ActiveIncident \ src \ Product \ Service \ Models \ ModelBuilder.cs中的Microsoft.OneIM.ActiveIncident.Service.ModelBuilder.BuildIncidentModels（）：第42行在c：\ OneIM \ EngSys \ OneIM \ ActiveIncident \ src \ Product \ Service \ App_Start \ WebApiConfig.cs中的Microsoft.OneIM.ActiveIncident.Service.WebApiConfig.Register（HttpConfiguration config）：第22行在c：\ OneIM \ EngSys \ OneIM \ ActiveIncident \ src \ Product \ ServiceHost \ ApiStartup.cs：第27行的Microsoft.OneIM.ActiveIncident.ServiceHost.ApiStartup.Configuration（IAppBuilder appBuilder）中

我的模型如下所示

    public class Incident
    {
            public IncidentImpact Impact { get; set; }
    }

[ComplexType]
public class IncidentImpact
{

    public bool IsCustomerImpacting { get; set; }

    public string SupportTicketId { get; set; }

    public ICollection<ImpactedService> ImpactedServices { get; set; }
}


public class ImpactedService
{

     public long Id { get; set; }


      public long IncidentId { get; set; }

    public Incident Incident { get; set; }

    public long ServiceId { get; set; }
}

Answer 1

虽然OData协议V4支持复杂类型包含实体作为导航属性，但OData Lib和WebAPI OData现在都不实现此功能。

Answer 2

您必须按[key]属性设置键属性，或者在模型构建器中设置为

builder.EntitySet<Type>("Types").EntityType.HasKey(t => t.KeyProperty);

希望它有所帮助。

WebAPI和Odata V4问题：包含实体的ComplexType
