我有这个型号和配置
public class Person
{
public int? FatherId { get; set; }
public virtual Person Father { get; set; }
public int? MotherId { get; set; }
public virtual Person Mother { get; set; }
public virtual List<Person> Childs { get; set; }
}
class PersonConfiguration : EntityTypeConfiguration<Person>
{
public PersonConfiguration()
{
HasOptional(e => e.Father).WithMany(e => e.Childs)
.HasForeignKey(e => e.FatherId);
HasOptional(e => e.Mother).WithMany(e => e.Childs)
.HasForeignKey(e => e.MotherId);
}
}
我得到这个类型是初始的错误.
Schema specified is not valid. Errors: (151,6) : error 0040: Type
Person_Father is not defined in namespace ExamModel (Alias=Self).
解决方法
无法将两个导航属性映射到单个集合属性.它看起来很嘲笑,但你必须有两个集合属性
public class Person
{
public int? FatherId { get; set; }
public virtual Person Father { get; set; }
public int? MotherId { get; set; }
public virtual Person Mother { get; set; }
public virtual List<Person> ChildrenAsFather { get; set; }
public virtual List<Person> ChildrenAsMother { get; set; }
}
class PersonConfiguration : EntityTypeConfiguration<Person>
{
public PersonConfiguration()
{
HasOptional(e => e.Father).WithMany(e => e.ChildrenAsFather)
.HasForeignKey(e => e.FatherId);
HasOptional(e => e.Mother).WithMany(e => e.ChildrenAsMother)
.HasForeignKey(e => e.MotherId);
}
}
