在Entity Framework Core中使用[ComplexType] [英] Using [ComplexType] in Entity Framework Core

问题描述

我正在EF Core数据模型中使用自己的类的属性.

I'm using a property of my own class inside EF Core data model.

public class Currency
{
    public string Code { get; set; }
    public string Symbol { get; set; }
    public string Format { get; set; }
}

[ComplexType]
public class Money
{
    public int? CurrencyID { get; set; }
    public virtual Currency Currency { get; set; }
    public double? Amount { get; set; }
}

public class Rate
{
    public int ID { get; set; }
    public Money Price = new Money();
}

我的问题是，当我尝试创建迁移时，EF Core报告一个错误.

My problem is that when I try to create a migration, EF Core reports a error.

Microsoft.Data.Entity.Metadata.ModelItemNotFoundException: The entity type 'RentABike.Models.Money' requires a key to be defined.

如果我声明一个密钥，则会为"Money"创建一个单独的表，这不是我想要的.

If I declare a key, a separate table for "Money" is created, which is not what I'm looking for.

是否可以在EF Core中使用ComplexType并将其全部放入单个表中?

Is there any way to use ComplexType in EF Core and put it all into a single table?

推荐答案

当前支持积压的复杂类型

Support for complex types is currently on the backlog https://github.com/aspnet/EntityFramework/issues/246
