null id Orchard存储库创建标识身份

我使用Orchard创建一个包含此代码的新条目

_repository.Create(new GMapZonePartRecord {
                Name = model.Name,
                Description = model.Description,
                Commune = model.Commune,
                Quarter = model.Quarter,
                Price = model.Price,
                StartZoom = model.StartZoom,
                StopZoom = model.StopZoom,
                Color = model.Color,
                GMapPartRecord = partRecord
            });

其中_repository是IRepository。 我的代码很久以前就已经开始了，现在我得到了一个例外 我的列标识是migration.cs中的标识：

SchemaBuilder.CreateTable("GMapZonePartRecord",
            table => table
                .Column<int>("Id", col => col.PrimaryKey().Identity())
                .Column<string>("Name")
                .Column<string>("Description")
                .Column<string>("Color")
                .Column<int>("GMapPartRecord_Id"));

以下是错误的详细信息：

感谢您的帮助，我真的不知道在哪里搜索。

编辑： 在添加了Nhibernate 3.3.X的源代码后，我发现失败的检查不是ContentItemRecord的空值。 有什么想法吗？

2 个答案:

答案 0 :(得分：2)

您永远不应该使用Repository<TRecord>来创建部分记录（并且您几乎不应该使用Repository<TRecord>，句号）。使用您的代码，您创建了与内容项不对应的孤立部件记录。相反，使用ContentManager上的API，它将负责为您创建所有相关记录。

答案 1 :(得分：0)

要调试我从https://github.com/nhibernate/nhibernate-core/tree/3.3.x下载NHibernate源代码 并发现null值不是id就像错误消息让我们思考而是ContentItemRecord。

所以我只是在这上面添加新值：

_repository.Create(new GMapZonePartRecord
            {
                Name = model.Name,
                Description = model.Description,
                Commune = model.Commune,
                Quarter = model.Quarter,
                Price = model.Price,
                StartZoom = model.StartZoom,
                StopZoom = model.StopZoom,
                Color = model.Color,
                GMapPartRecord = partRecord,
                ContentItemRecord = new ContentItemRecord()
            });

现在一切正常：）
