C# 用于从ReadModel映射到实体的Odata配置

我使用的是

Microsoft.AspNetCore.OData 7.3.0

我的实体类：

public class ProjectReport
{
    public int OptionId { get; set; }
    public int Hash { get; set; }
    public int ProjectNo { get; set; }
    public int RevisionNo { get; set; }
    public int OptionNo { get; set; }
    public string CreatedBy { get; set; }
    // many more
}

我想公开一个ReadModel

StandardProjectReportReadModel的配置当前如下所示：

public class StandardProjectReportModelConfiguration : IModelConfiguration
{
    private static readonly ApiVersion V1 = new ApiVersion(1, 0);

    private EntityTypeConfiguration<StandardProjectReportReadModel> ConfigureCurrent(ODataModelBuilder builder)
    {
        var order = builder.EntitySet<StandardProjectReportReadModel>("StandardProjectReport").EntityType;

        order.HasKey(p => p.OptionId);

        return order;
    }

    public void Apply(ODataModelBuilder builder, ApiVersion apiVersion)
    {
        // note: the EDM for orders is only available in version 1.0
        if (apiVersion == V1)
        {
            ConfigureCurrent(builder);
        }
    }
}

[HttpGet]
[ODataRoute]
[EnableQuery(PageSize = 300)]
public IQueryable<ControllingProjectReportReadModel> Get(ODataQueryOptions<ControllingProjectReportReadModel> odataQuery)
{
    // Apply the filter as we are working on the Entity and project back to a model
    var executedQuery = _readContext.ProjectReport.Get(_mapper, odataQuery);

    return _mapper.Map<IList<ControllingProjectReportReadModel>>(executedQuery).AsQueryable();
}

公共类StandardProjectReportModelConfiguration:IModelConfiguration
{
私有静态只读ApiVersion V1=新ApiVersion（1,0）；

{
var order=builder.EntitySet（“StandardProjectReport”）.EntityType；

}
公共无效应用（ODataModelBuilder builder，ApiVersion）
{
//注：订单的EDM仅在版本1.0中可用

{

}
}
}

我的控制器：

[Authorize]

[ODataRoutePrefix("StandardProjectReport")]
[ApiExplorerSettings(IgnoreApi = false)]
public class StandardProjectReportController : ODataController
{
    private readonly IReportingReadOnlyContext _readContext;
    private readonly IIdentityService _identityService;
    private readonly IMapper _mapper;

    public StandardProjectReportController(IReportingReadOnlyContext readContext, IIdentityService identityService, IMapper mapper)
    {
        _readContext = readContext;
        _identityService = identityService;
        _mapper = mapper;
    }

    [HttpGet]
    [ODataRoute]
    [EnableQuery(PageSize = 300)]
    public IQueryable<StandardProjectReportReadModel> Get(ODataQueryOptions<ProjectReport> odataQuery)
    {
        var userId = "MyId;

        // Apply the filter as we are working on the Entity and project back to a model
        var executedQuery = _readContext.GetProjectReportsFilteredByCwsId(userId).Get(_mapper, odataQuery);

        return _mapper.Map<IList<StandardProjectReportReadModel>>(executedQuery).AsQueryable();
    }
}

}
}

当我呼叫时：我得到一个异常：

System.ArgumentException:给定模型不包含类型“Reporting.Core.Models.ProjectReport”。（参数“elementClrType”） 位于Microsoft.AspNet.OData.ODataQueryContext..ctor（IEdmModel模型，类型elementClrType，ODataPath路径） 位于Microsoft.AspNet.OData.ODataQueryParameterBindingAttribute.ODataQueryParameterBinding.BindModelAsync（ModelBindingContext bindingContext） 位于Microsoft.AspNetCore.Mvc.ModelBinding.Binders.BinderTypeModelBinder.BindModelAsync（ModelBindingContext绑定上下文） 位于Microsoft.AspNetCore.Mvc.ModelBinding.ParameterBinder.BindModelAsync（ActionContext ActionContext、IModelBinder modelBinder、IValueProvider valueProvider、ParameterDescriptor参数、ModelMetadata元数据、对象值） 在Microsoft.AspNetCore.Mvc.Controllers.ControllerBinderDelegateProvider.c_uuDisplayClass0_0.d.MoveNext（）中

我的问题：如何配置ReadModel和Entity之间的映射？

看起来是控制器导致了错误

我需要传递

ODataQueryOptions-odataQuery

而不是

ODataQueryOptions-odataQuery

控制器方法现在看起来像：

public class StandardProjectReportModelConfiguration : IModelConfiguration
{
    private static readonly ApiVersion V1 = new ApiVersion(1, 0);

    private EntityTypeConfiguration<StandardProjectReportReadModel> ConfigureCurrent(ODataModelBuilder builder)
    {
        var order = builder.EntitySet<StandardProjectReportReadModel>("StandardProjectReport").EntityType;

        order.HasKey(p => p.OptionId);

        return order;
    }

    public void Apply(ODataModelBuilder builder, ApiVersion apiVersion)
    {
        // note: the EDM for orders is only available in version 1.0
        if (apiVersion == V1)
        {
            ConfigureCurrent(builder);
        }
    }
}

[HttpGet]
[ODataRoute]
[EnableQuery(PageSize = 300)]
public IQueryable<ControllingProjectReportReadModel> Get(ODataQueryOptions<ControllingProjectReportReadModel> odataQuery)
{
    // Apply the filter as we are working on the Entity and project back to a model
    var executedQuery = _readContext.ProjectReport.Get(_mapper, odataQuery);

    return _mapper.Map<IList<ControllingProjectReportReadModel>>(executedQuery).AsQueryable();
}

{
//当我们处理实体并将其投影回模型时，应用过滤器
var executedQuery=\u readContext.ProjectReport.Get（\u mapper，odataQuery）；

}
