Question

我正在尝试运行RavenDB转换，但我遇到了以下异常：

Raven.Imports.Newtonsoft.Json.JsonSerializationException：无法读取属性值：Id ---＆gt; System.FormatException：输入字符串的格式不正确。

我认为这是因为我的模型使用整数ID而不是字符串。如何让转换与int一起使用？

DiscountCode_ViewModel.cs

public class DiscountCode_ViewModel : AbstractTransformerCreationTask<DiscountCode>
{
    public DiscountCode_ViewModel()
    {
        TransformResults = discounts => discounts
            .Select(discount => new SimpleDiscountCode
            {
                // Throws an exception here
                Id = discount.Id,
                MerchantId = discount.MerchantId,
                TermsAndConditions = discount.TermsAndConditions,
                Code = discount.Code,
                Description = discount.Description
            });
    }
}

DiscountCode.cs

public class DiscountCode
{
    public int Id { get; set; }
    public int MerchantId { get; set; }
    public string Description { get; set; }
    public string Code { get; set; }
    public string TermsAndConditions { get; set; }

    public DateTime StartDate { get; set; }
    public DateTime EndDate { get; set; }
    public int SortOrder { get; set; }

    // a bunch more properties...
}

SimpleDiscountCode.cs

public class SimpleDiscountCode
{
    public int Id { get; set; }
    public int MerchantId { get; set; }
    public string Title { get; set; }
    public string Code { get; set; }
    public string TermsAndConditions { get; set; }
}

DiscountCode_ByMerchantId.cs

public class DiscountCodes_ByMerchantId : AbstractIndexCreationTask<DiscountCode>
{
    public DiscountCodes_ByMerchantId()
    {
        Map = discounts => discounts
            .Select(discount => new
            {
                discount.MerchantId,
                discount.StartDate,
                discount.EndDate,
                discount.SortOrder
            });

        Sort(x => x.SortOrder, SortOptions.Int);
    }
}

Query.cs

var discounts = await session
                .Query<DiscountCode, DiscountCodes_ByMerchantId>()
                .Include<DiscountCode, Merchant>(d => d.MerchantId)
                .Where(x => x.MerchantId == id)
                .Where(x => x.StartDate <= DateTime.Now && x.EndDate >= DateTime.Now)
                .OrderBy(x => x.SortOrder)
                .TransformWith<DiscountCode_ViewModel, SimpleDiscountCode>()
                .ToListAsync();

var merchant = await session.LoadAsync<Merchant>(id);
