无法确定类型之间关联的主体结束 [英] Unable to determine the principal end of an association between the types

问题描述

我收到此错误：

无法确定
类型之间的关联的主体结尾CustomerDetail和客户

Unable to determine the principal end of an association between the types CustomerDetail and Customer.

这是我的客户和 CustomerDetail 模型

[Table("CUSTOMER")]
public class Customer
{
    [Required]
    [Column("CUSTOMER_ID")]
    public int Id {get; set;}

    [Column("FIRST_NAME")]
    public string FirstName {get; set;}
    // other fields  

    public virtual CustomerDetail customerDetail {get; set;}
}

[Table("CUSTOMER_DETAIL")]
public class CustomerDetail
{
    [Required]
    [Column("CUSTOMER_DETAIL_ID")]
    public int Id {get; set;}
    // other fields

    public virtual Customer Customer {get; set;} 
}

客户到 CustomerDetail 具有1：1关系。

Customer to CustomerDetail has a 1:1 relation.

推荐答案

我认为你必须指定一个 ForeignKey c>客户属性映射到实体上存在的关键属性。

I think that you have to specify a ForeignKey relation on the Customer property that maps to the key property exists on the entity.

[Table("CUSTOMER_DETAIL")]
public class CustomerDetail
{
    [Required]
    [Column("CUSTOMER_DETAIL_ID")]
    public int Id {get; set;}
    // other fields

    [ForeignKey("Id")]
    public virtual Customer Customer {get; set;} 
}

这个问题引用了一个不同的错误，但是有一个类似的目标是什么你正在努力实现。
