odata - SharePoint Online BCS OData 外部内容无法更新、查看或删除

Question

使用 Visual Studio 2013，我在现有数据库上创建了一个实体模型。每个表都有一个主键的 GUID。我创建了一个带有相关 OData 绑定和控制器的 MVC Web API 项目。

这是我创建 OData 绑定的方法；

ODataConventionModelBuilder builder = new ODataConventionModelBuilder();

builder.EntitySet<HRPosition>("HRPositions").EntityType.HasKey(p=>p.HTPositionGuid);

这是 HRPositions 实体的示例控制器。

   public class HRPositionsController : ODataController
{
    private EFSEntities db = new EFSEntities();

    // GET: odata/HRPositions
    [EnableQuery]
    public IQueryable<HRPosition> GetHRPositions()
    {
        return db.HRPositions;
    }

    // GET: odata/HRPositions(5)
    [EnableQuery]
    public SingleResult<HRPosition> GetHRPosition([FromODataUri] Guid key)
    {
        return SingleResult.Create(db.HRPositions.Where(hRPosition => hRPosition.HTPositionGuid == key));
    }

    // PUT: odata/HRPositions(5)
    public async Task<IHttpActionResult> Put([FromODataUri] Guid key, Delta<HRPosition> patch)
    {
        Validate(patch.GetEntity());

        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        HRPosition hRPosition = await db.HRPositions.FindAsync(key);
        if (hRPosition == null)
        {
            return NotFound();
        }

        patch.Put(hRPosition);

        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!HRPositionExists(key))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return Updated(hRPosition);
    }

    // POST: odata/HRPositions
    public async Task<IHttpActionResult> Post(HRPosition hRPosition)
    {
        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        db.HRPositions.Add(hRPosition);

        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateException)
        {
            if (HRPositionExists(hRPosition.HTPositionGuid))
            {
                return Conflict();
            }
            else
            {
                throw;
            }
        }

        return Created(hRPosition);
    }

    // PATCH: odata/HRPositions(5)
    [AcceptVerbs("PATCH", "MERGE")]
    public async Task<IHttpActionResult> Patch([FromODataUri] Guid key, Delta<HRPosition> patch)
    {
        Validate(patch.GetEntity());

        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        HRPosition hRPosition = await db.HRPositions.FindAsync(key);
        if (hRPosition == null)
        {
            return NotFound();
        }

        patch.Patch(hRPosition);

        try
        {
            await db.SaveChangesAsync();
        }
        catch (DbUpdateConcurrencyException)
        {
            if (!HRPositionExists(key))
            {
                return NotFound();
            }
            else
            {
                throw;
            }
        }

        return Updated(hRPosition);
    }

    // DELETE: odata/HRPositions(5)
    public async Task<IHttpActionResult> Delete([FromODataUri] Guid key)
    {
        HRPosition hRPosition = await db.HRPositions.FindAsync(key);
        if (hRPosition == null)
        {
            return NotFound();
        }

        db.HRPositions.Remove(hRPosition);
        await db.SaveChangesAsync();

        return StatusCode(HttpStatusCode.NoContent);
    }

    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            db.Dispose();
        }
        base.Dispose(disposing);
    }

    private bool HRPositionExists(Guid key)
    {
        return db.HRPositions.Count(e => e.HTPositionGuid == key) > 0;
    }
}

一旦部署了 OData 服务并使用 Fiddler，我就可以查询服务端点并检索完整的数据列表以及单个实体数据。

然后，我创建了一个 SharePoint 应用程序，在其中我通过引用 OData 服务创建了一个外部内容类型。这将为每个端点创建 ECT 模型定义。

这是 HRPositions 的 ECT；

我将 ECT 上传到 SharePoint Online BCS 中，一切看起来都很好；

从那里我创建一个外部列表并引用 HRPositions ECT，它创建和 SP 列表但缺少主键（即 GUID）。

此视图显示正确的数据；

我可以在列表中添加一个新项目；

它显示在阅读所有视图中；

但是我无法编辑、删除或查看任何列表项，因为每次操作都会出现此错误；

我附加到 OData Web 服务，可以看到问题发生的原因。事实证明，从 OData 服务反映的 Visual Studio 中的自动生成的外部控制类型 (ECT) 存在问题，因为出于某种原因，它将请求制定为 /HRPositions(HTPositionGuid=guid'@HTPositionGuid');

它实际上应该只是 /HRPositions(guid'@HTPositionGuid');

谁能告诉我为什么在参数列表中包含 HTPositionGuid=？

我可以为每个实体手动编辑代码生成的 ECT 文件，但这似乎很愚蠢。
