C# Orchard 1-N关系（停止内容项更新）

背景：

这是我的轨道部件的型号：

    public class TrackPartRecord : ContentPartRecord
    {
        public virtual IList<TrackInformationRecord> Tracks { get; set; }
    }

    public class TrackPart : ContentPart<TrackPartRecord>
    {
        public IList<TrackInformationRecord> Tracks
        {
            get { return Record.Tracks; }
        }
    }

    public class TrackInformationRecord
    {
        public virtual int Id { get; set; }
        public virtual int TrackPartId { get; set; }
        public virtual string Title { get; set; }
        public virtual string Description { get; set; }
        public virtual bool IsDeleted { get; set; }

        public virtual IList<SessionInformationRecord> Sessions { get; set; }
   }

    public class SessionInformationRecord
    {
        public virtual int Id { get; set; }
        public virtual int TrackId { get; set; }
        public virtual string Title { get; set; }
        public virtual string Description { get; set; }
        public virtual DateTime Timeslot { get; set; }
        public virtual bool HasEvaluation { get; set; }
        public virtual bool IsDeleted { get; set; }
    }

内容项附加跟踪部分（形成1-n关系），跟踪记录具有会话记录列表

添加轨迹时，问题开始出现。将添加第一个添加的轨迹。在第一次更新之后（添加第一首曲目，还没有会话），我不再能够更新内容项上的任何内容。当我浏览代码时，我没有得到任何错误或异常（可能它们埋在Orchard中太深了，没有直接抛出任何明显的东西）

当我直接进入数据库并删除与内容项相关的跟踪记录时，我能够再次更新所有内容

我检查了日志，发现：

2013-08-14 14:15:00,882 [30] NHibernate.AdoNet.AbstractBatcher - Could not execute command: UPDATE Ignite_EventsAgenda_SessionInformationRecord SET TrackInformationRecord_id = null WHERE TrackInformationRecord_id = @p0

[ Node name (if any) = ,Column name = TrackInformationRecord_id ]

首先，我不知道为什么会出现“列名无效”的问题

其次，我不明白这一行：updateignite\u EventsAgenda\u SessionInformationRecord SET TrackInformationRecord\u id=null，其中TrackInformationRecord\u id=@p0

它从哪里获得了列名称TrackInformationRecord\u id

任何帮助或建议都将不胜感激。

是的，应该用斜杠命名，类型可以用记录类名而不是int。您还应该将Datetime设置为nullable:Datetime？

您可以这样尝试吗（为了简单起见，我省略了会话，但您可以复制相同的内容）：

公共类TrackPartRecord:ContentPartRecord
{
公共虚拟IList跟踪{get；set；}
}
公共类轨道信息记录
{
//自有财产
公共虚拟整数Id{get；set；}
公共虚拟字符串标题{get；set；}
公共虚拟字符串描述{get；set；}
公共虚拟布尔被删除{get；set；}
//关系性质
公共虚拟TrackPartRecord TrackPartRecord{get；set；}
}

在移民方面：

        SchemaBuilder.CreateTable("TrackPartRecord", t => t
            .ContentPartRecord()
            );

        SchemaBuilder.CreateTable("TrackInformationRecord", t => t
            .Column<int>("Id", column => column.PrimaryKey().NotNull())
            .Column<int>("TrackPartRecord_Id")
            .Column<string>("Title", c => c.WithLength(50).NotNull())
            .Column<string>("Description", c => c.NotNull())
            .Column<bool>("IsDeleted")
           );

schemabilder.CreateTable（“TrackPartRecord”，t=>t
.ContentPartRecord（）
);
CreateTable（“TrackInformationRecord”，t=>t
.Column（“Id”，Column=>Column.PrimaryKey（）.NotNull（））
.列（“TrackPartRecord\u Id”）
.Column（“Title”，c=>c.WithLength（50）.NotNull（）
.Column（“Description”，c=>c.NotNull（））
.栏（“删除”）
);

public class TrackPartRecord : ContentPartRecord
{
    public virtual IList<TrackInformationRecord> Tracks { get; set; }
}

public class TrackInformationRecord
{
    // Own properties
    public virtual int Id { get; set; }
    public virtual string Title { get; set; }
    public virtual string Description { get; set; }
    public virtual bool IsDeleted { get; set; }

    // Relations properties
    public virtual TrackPartRecord TrackPartRecord { get; set; }
}

        SchemaBuilder.CreateTable("TrackPartRecord", t => t
            .ContentPartRecord()
            );

        SchemaBuilder.CreateTable("TrackInformationRecord", t => t
            .Column<int>("Id", column => column.PrimaryKey().NotNull())
            .Column<int>("TrackPartRecord_Id")
            .Column<string>("Title", c => c.WithLength(50).NotNull())
            .Column<string>("Description", c => c.NotNull())
            .Column<bool>("IsDeleted")
           );

public class TrackInformationRecord
{
    public virtual IList<SessionInformationRecord> Sessions { get; set; }
}

public class TrackInformationRecordOverride
    : IAutoMappingOverride<TrackInformationRecord>
{
    public void Override(AutoMapping<TrackInformationRecord> mapping)
    {
        mapping.HasMany(x => x.Sessions)
            .KeyColumn("TrackId"); // ... assuming TrackId is the column you wanted.
    }
}
