OData无法识别我的收藏夹属性 [英] OData Doesn't Recognize My Collection Properties
问题描述
当我发布的ShakeoutDocument中没有填充集合时，OData Serializer会理解JSON&正确填充ODataActionParameters.
When I post a ShakeoutDocument without the collections populated, the OData Serializer understands the JSON & populates the ODataActionParameters correctly.
但是，当我将子记录添加到任一ShakeoutDocument's集合属性中时，Odata Controller's ODataActionParameters参数为空.我将其范围缩小到了OData EDM Model Configuration.
However, when I add a child-record into either of the ShakeoutDocument's collection properties...the Odata Controller's ODataActionParameters parameter is null. I have narrowed it down to the OData EDM Model Configuration.
- 如何正确地将收集"属性(如下所示)表征"到EDM模型配置中
喜欢的班级:
这些集合是详细信息"和封条(下)
THE CLASS LOOKS LIKE:
The collections are the Details & Seals (below)
public class ShakeoutDocument : Document
{
public IObjectState ObjectState { get; set; } //<-- This "registers" just fine?
public int ShakeoutId { get; set; }
public string SchedulingBatch { get; set; }
public int? ProductId { get; set; }
public decimal? Gravity { get; set; }
public decimal? Temperature { get; set; }
public decimal? SedimentAndWater { get; set; }
public DateTime? BatchEndDate { get; set; }
public DateTime? SampleWorkedDate { get; set; }
public string Witness { get; set; }
public string Notes { get; set; }
public List<ShakeoutDetail> Details { get; set; } //<-- How do I "register" this?
public List<ShakeoutSeal> Seals { get; set; } //<-- How do I "register" this?
}
我当前的EDM配置外观如下:
我尝试了定义为 HERE 的各种方法.奇怪的是... IObjectState注册就好了.
MY CURRENT EDM CONFIGURATION LOOKS LIKE:
I have tried various approaches as defined HERE. The odd thing is...IObjectState registers just fine.

发送此JSON作品:
如果我SEND，则此JSON无需填充详细信息"和"Seals collections..it正确序列化.
SENDING THIS JSON WORKS:
If I SEND this JSON WITHOUT populating the Details & Seals collections..it serializes correctly.
如果我填充详细信息"和密封收集...参数为NULL.
If I populate the Details & Seals collections...the parameter is NULL.

为了完整起见，我包括了...
THE UNBOUND FUNCTION LOOKS LIKE:
For completeness, I am including this...

LogException(ex);

更新1:
$ MetaData似乎了解收集类型...
UPDATE 1:
The $MetaData seems to understand the collection types...
<EntityType Name="ShakeoutDocument" BaseType="Pulse.Document">
<Property Name="ObjectState" Type="Pulse.IObjectState" Nullable="false"/>
<Property Name="ShakeoutId" Type="Edm.Int32" Nullable="false"/>
<Property Name="SchedulingBatch" Type="Edm.String"/>
<Property Name="ProductId" Type="Edm.Int32"/>
<Property Name="Gravity" Type="Edm.Decimal"/>
<Property Name="Temperature" Type="Edm.Decimal"/>
<Property Name="SedimentAndWater" Type="Edm.Decimal"/>
<Property Name="BatchEndDate" Type="Edm.DateTimeOffset"/>
<Property Name="SampleWorkedDate" Type="Edm.DateTimeOffset"/>
<Property Name="Witness" Type="Edm.String"/>
<Property Name="Notes" Type="Edm.String"/>
<NavigationProperty Name="Details" Type="Collection(Pulse.ShakeoutDetail)"/>
<NavigationProperty Name="Seals" Type="Collection(Pulse.ShakeoutSeal)"/>
</EntityType>
更新2:
我刚刚注意到... ShakeoutDetails& ShakeoutDetail的NavigationPropertyBinding为"Meter" ...在ShakeoutDocument中不存在(并且由于它不是实体，所以不会包含在内).
UPDATE 2:
I just noticed...ShakeoutDetails & ShakeoutDetail have a NavigationPropertyBinding of "Meter"...which is not present in ShakeoutDocument (and never will be included as this is a Model not an Entity).

推荐答案
根据您的上一次更新，我认为导航属性绑定很有趣.
In according your last update i think problem interesting with navigation property binding.
它不能解决仪表问题，您应该查看 https://odata. github.io/WebApi/13-03-NavigationPropertyBindingWithComplexType/ (如果需要，还可以查看瞬态操作")
It does not resolve Meter, you should look that https://odata.github.io/WebApi/13-03-NavigationPropertyBindingWithComplexType/ (Also look Transient Actions, if you needed)
