“類型 {type} 上不存在屬性 {property}” - 但它確實存在。 OData 配置問題？

[英]“The property {property} does not exist on type {type}” - but it does. OData configuration issue?

問題描述

我有一個具有 OData 后端的 Blazor WASM 應用程序。 我正在嘗試配置我的一個模型的 NavigationProperty，以便我可以使用$expand=查詢參數返回更多數據，但是在嘗試發出PATCH請求時我不斷收到以下錯誤（ GET工作正常）：

Microsoft.OData.ODataException: The property 'JobId' does not exist on type 'Coin.ODataOrderHeader'. Make sure to only use property names that are defined by the type or mark the type as open type.

但它確實存在：不只是在模型中：

public partial class ODataOrderHeader
{
        [Key]
        public int OrderId { get; set; }

        [Column("JobID")]
        [ForeignKey("Job")]
        public int JobId { get; set; }
        ...
        [System.Text.Json.Serialization.JsonPropertyName("Job")]
        public virtual Jobs Job { get; set; }
}

但在$metadata文檔中也是如此：

<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx">
    <edmx:DataServices>
        <Schema Namespace="Coin" xmlns="http://docs.oasis-open.org/odata/ns/edm">
            ...
            <EntityType Name="ODataOrderHeader">
                <Key>
                    <PropertyRef Name="OrderId" />
                </Key>
                <Property Name="OrderId" Type="Edm.Int32" Nullable="false" />
                <Property Name="JobId" Type="Edm.Int32" />
                ...
                <NavigationProperty Name="Job" Type="Coin.Jobs">
                    <ReferentialConstraint Property="JobId" ReferencedProperty="JobId" />
                </NavigationProperty>
            </EntityType>
            ...
        </Schema>
    </edmx:DataServices>
</edmx:Edmx>

這是創建 model 的代碼：

        private IEdmModel GetEdmModel()
        {
            var builder = new ODataConventionModelBuilder();
            builder.Namespace = "Coin";
            builder.ContainerName = "CoinContainer";
            ...
            var orders = builder.EntitySet<ODataOrderHeader>("Orders");
            return builder.GetEdmModel();
        }

我應該指出， ODataOrderHeader是 DTO 類型，而Jobs是 EF 腳手架類型。

下面是調用 API 的Simple.OData.Client代碼：

    private async void UpdateItem()
    {
        ODataClient client = new ODataClient(new ODataClientSettings(HttpClient, new Uri("odata", UriKind.Relative)));

        await client.For<ODataOrderHeader>("Orders")
            .Key(currentOrder.OrderId)
            .Set(currentOrder)
            .UpdateEntryAsync();
    }

這是上面代碼調用的 controller 操作：

        [ODataRoute("/orders({key})")]
        public async Task<IActionResult> Patch([FromODataUri] int key, Delta<ODataOrderHeader> order)
        {
            if (!ModelState.IsValid)
                return BadRequest();

            ...
        }

最后，完整的錯誤消息：

是否有我遺漏的配置錯誤或 controller 操作有問題？

對於將來偶然發現這一點的任何人，我能夠發現更多信息。

首先，通過在我的 Jobs class 上添加一些數據注釋[IgnoreDataMember]並在實例化ODataClient時添加{IgnoreUnmappedProperties = true} ，我能夠得到一個不同的錯誤。 類似於以下內容： The key 'JobId' does not exist in the dictionary 。

對於上下文，我正在嘗試執行 OData 所指的“深度更新” 。 我想在更新父實體的同時更新子實體。 但是，Simple.OData.Client 不支持深度更新或深度鏈接或深度創建。 這是來自 Simple.OData.Client 的 GitHub 頁面的一個 5 年前的問題，該頁面談到了這一點，不幸的是，這個 package 的開發似乎已經停止（ “Simple.OData.Client 的未來”和“Project Dead？” ）。 由於它不支持“深度更新”，它不知道如何生成請求 URL 這就是我的PATCH請求失敗的原因。
