null id Orchard 存储库创建 Id 身份
null id Orchard repository creation Id identity on
我使用 Orchard 使用此代码创建一个新条目
_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可以工作，现在出现异常
我的列 id 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"));
错误详情如下：

谢谢大家的帮助，我真的不知道去哪里找。
编辑：
添加Nhibernate 3.3.X源后，发现检查失败的不是ContentItemRecord的空值。
有什么想法吗？
你永远不应该使用 Repository<TRecord> 来创建零件记录（你几乎不应该使用 Repository<TRecord>，句点）。使用您的代码，您创建了与内容项不对应的孤立部分记录。相反，请使用 ContentManager 上的 API，它会负责为您创建所有关联记录。
为了调试，我从 https://github.com/nhibernate/nhibernate-core/tree/3.3.x 下载了 NHibernate 源代码
并发现空值不是像错误消息那样的 id 让我们思考而是 ContentItemRecord.
所以我只是在上面添加了新的值：
_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:)
