Question

我正在建模一个服务业务，在每次访问客户端时执行多项服务。我有一个Visit表，一个Service表和一个链接表，VisitService。我在我的服务中使用此请求DTO来获取访问服务列表：

    [Route("/visits/{visitid}/services", Verbs = "GET")]
    public class ServicesAtVisit : QueryBase<VisitService, ServiceAtVisit>, IJoin<VisitService, My.Namespace.Service> {
    public int VisitId { get; set; }
}

ServiceAtVisit是我投射的自定义DTO。

因为我的一个DTO是一个不幸的名字＆＃34; Service＆＃34;，我必须在IJoin中完全限定它，因为否则，它与ServiceStack.Service不明确。现在，当我点击路线时，我收到错误＆＃34;无法推断VisitService和Service＆＃34;之间的关系。

有趣的是，我已经使用了其他多对多关系（Client.AssignedStaffMembers，StaffMember.AssignedClients for tables Client - ＆gt; ClientStaffMember - ＆gt; StaffMember），我可以＆＃39看到不同的东西。

问题是我的DTO的名称以及我必须完全符合条件的事实吗？

访问：

    [Route("/visits", Verbs = "POST")]
public partial class Visit {
    [AutoIncrement]
    public long Id { get; set; }
    public int ServiceRequestId { get; set; }
    public string TimeOfDay { get; set; }
    public DateTime Date { get; set; }
    public TimeSpan? PreferredStartTime { get; set; }
    public TimeSpan? PreferredEndTime { get; set; }
    public bool IsFirstVisit { get; set; }
    public bool IsLastVisit { get; set; }
    public bool IncursWeekendFee { get; set; }
    public bool WaiveWeekendFee { get; set; }
    public bool IncursHolidayFee { get; set; }
    public bool WaiveHolidayFee { get; set; }
    public bool IncursLastMinuteSchedulingFee { get; set; }
    public bool WaiveLastMinuteSchedulingFee { get; set; }
    public bool IncursLastMinuteCancellationFee { get; set; }
    public bool WaiveLastMinuteCancellationFee { get; set; }
    public int? StaffMemberId { get; set; }
    public string Notes { get; set; }
    public bool IsCancelled { get; set; }
    public DateTime? CheckInDateTime { get; set; }
    public int? CheckInStaffMemberId { get; set; }
    public DateTime? CheckOutDateTime { get; set; }
    public int? CheckOutStaffMemberId { get; set; }

    [Ignore]
    public ServiceRequest ServiceRequest { get; set; }

    [Ignore]
    public StaffMember StaffMember { get; set; }

    [Ignore]
    public List<ServiceAtVisit> ServicesAtVisit { get; set; }
}

VisitService：

    public partial class VisitService {

    // Workaround for composite key limitation
    public string Id {
        get {
            return this.VisitId.ToString() + "|" + this.ServiceId.ToString();
        }
    }

    public long VisitId { get; set; }
    public int ServiceId { get; set; }
    public int Quantity { get; set; }
    public bool FeeIsWaived { get; set; }

    [Ignore]
    public Visit Visit { get; set; }

    [Ignore]
    public Service Service { get; set; }
}

服务：

    public partial class Service {
    [AutoIncrement]
    public int Id { get; set; }
    public int ServiceTypeId { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public int DisplayOrder { get; set; }
    public bool IsHourly { get; set; }
    public bool IsMonthly { get; set; }

    [Ignore]
    public ServiceType ServiceType { get; set; }

    [Ignore]
    public ServicePrice CurrentPrice { get; set; }
}

将结果投影到ServiceAtVisit：

    public partial class ServiceAtVisit {
    public int ServiceTypeId { get; set; }
    public string Name { get; set; }
    public string Description { get; set; }
    public int DisplayOrder { get; set; }
    public bool IsHourly { get; set; }
    public bool IsMonthly { get; set; }

    public int VisitId { get; set; }
    public int ServiceId { get; set; }
    public int Quantity { get; set; }
    public bool FeeIsWaived { get; set; }
}

我刚刚尝试创建一个AutoQuery服务，其中包含您在自定义MyNamespace下提供的所有类型，并且它按预期工作（在最新的ServiceStack中），即：

服务定义：

namespace MyNamespace
{
    [Route("/visits/{VisitId}/services", Verbs = "GET")]
    public class ServicesAtVisit : QueryBase<VisitService, ServiceAtVisit>, 
        IJoin<VisitService, Service>
    {
        public int VisitId { get; set; }
    }

    public partial class ServiceAtVisit
    {
        public int ServiceTypeId { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public int DisplayOrder { get; set; }
        public bool IsHourly { get; set; }
        public bool IsMonthly { get; set; }

        public int VisitId { get; set; }
        public int ServiceId { get; set; }
        public int Quantity { get; set; }
        public bool FeeIsWaived { get; set; }
    }
}

类型定义：

namespace MyNamespace
{
    [Route("/visits", Verbs = "POST")]
    public partial class Visit
    {
        [AutoIncrement]
        public long Id { get; set; }
        public int ServiceRequestId { get; set; }
        public string TimeOfDay { get; set; }
        public DateTime Date { get; set; }
        public TimeSpan? PreferredStartTime { get; set; }
        public TimeSpan? PreferredEndTime { get; set; }
        public bool IsFirstVisit { get; set; }
        public bool IsLastVisit { get; set; }
        public bool IncursWeekendFee { get; set; }
        public bool WaiveWeekendFee { get; set; }
        public bool IncursHolidayFee { get; set; }
        public bool WaiveHolidayFee { get; set; }
        public bool IncursLastMinuteSchedulingFee { get; set; }
        public bool WaiveLastMinuteSchedulingFee { get; set; }
        public bool IncursLastMinuteCancellationFee { get; set; }
        public bool WaiveLastMinuteCancellationFee { get; set; }
        public int? StaffMemberId { get; set; }
        public string Notes { get; set; }
        public bool IsCancelled { get; set; }
        public DateTime? CheckInDateTime { get; set; }
        public int? CheckInStaffMemberId { get; set; }
        public DateTime? CheckOutDateTime { get; set; }
        public int? CheckOutStaffMemberId { get; set; }

        //[Ignore]
        //public ServiceRequest ServiceRequest { get; set; }

        //[Ignore]
        //public StaffMember StaffMember { get; set; }

        [Ignore]
        public List<ServiceAtVisit> ServicesAtVisit { get; set; }
    }

    public partial class VisitService
    {
        // Workaround for composite key limitation
        public string Id
        {
            get
            {
                return this.VisitId.ToString() + "|" + this.ServiceId.ToString();
            }
        }

        public long VisitId { get; set; }
        public int ServiceId { get; set; }
        public int Quantity { get; set; }
        public bool FeeIsWaived { get; set; }

        [Ignore]
        public Visit Visit { get; set; }

        [Ignore]
        public Service Service { get; set; }
    }

    public partial class Service
    {
        [AutoIncrement]
        public int Id { get; set; }
        public int ServiceTypeId { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public int DisplayOrder { get; set; }
        public bool IsHourly { get; set; }
        public bool IsMonthly { get; set; }

        //[Ignore]
        //public ServiceType ServiceType { get; set; }

        //[Ignore]
        //public ServicePrice CurrentPrice { get; set; }
    }
}

测试数据：

using (var db = container.Resolve<IDbConnectionFactory>().Open())
{
    db.DropAndCreateTable<MyNamespace.Visit>();
    db.DropAndCreateTable<MyNamespace.VisitService>();
    db.DropAndCreateTable<MyNamespace.Service>();

    var visitId = db.Insert(new MyNamespace.Visit {
        Date = DateTime.UtcNow, Notes = "Notes"}, selectIdentity: true);
    var serviceId = (int)db.Insert(new MyNamespace.Service { 
        ServiceTypeId = 1, Name = "Name"}, selectIdentity:true);
    db.Insert(new MyNamespace.VisitService {
        VisitId = visitId, ServiceId = serviceId, Quantity = 1});
}

服务结果：

http://localhost:{port}/visits/1/services.json

JSON响应：

{
    offset: 0,
    total: 1,
    results: [{
        serviceTypeId: 1,
        name: "Name",
        displayOrder: 0,
        isHourly: false,
        isMonthly: false,
        visitId: 1,
        serviceId: 1,
        quantity: 1,
        feeIsWaived: false
    }]
}

ServiceStack ORMLite - 无法推断关系（因为DTO名称？）
