无法确定类型之间的关联的主要终点 [英] Unable to determine the principal end of an association between the types

问题描述

我得到这个错误：

无法确定为CustomerDetail的
类型之间的关联的主要结束，客户。

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

下面是我的客户和为CustomerDetail 模式

[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;} 
}

客户到为CustomerDetail 有一个1：1的关系。

Customer to CustomerDetail has a 1:1 relation.

推荐答案

我认为你必须指定在一个 ForeignKey的关系存在于实体映射到关键属性客户属性。

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;} 
}
