c# – Fluent api Cascade删除与一个表的关系

我有以下配置.我有一个用户.用户有邮政地址和物理地址(见下文). @H_404_5@

@H_404_5@

public class UserProfile
{
    public Guid UserProfileId {get; set;}

    public Guid PostalAddressId {get;set;}
    public virtual Address PostalAddress {get;set;}

    public Guid PhysicalAddressId {get;set;}
    public virtual Address PhysicalAddress {get;set;}
}

public class Address{
    public Guid AddressId {get;set;}
    public string LineOne {get;set;}
    public string LineTwo {get;set;}
    public string LineThree {get;set;}
}

@H_404_5@接下来是我流畅的映射

@H_404_5@

public UserProfileMapping()
{
    ToTable("UserProfile");
    HasKey(pk => pk.UserProfileId);
    Property(pr => pr.UserProfileId).HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);

    Hasrequired(a => a.PostalAddress).WithMany().HasForeignKey(fk => fk.PostalAddressId);
    Hasrequired(a => a.PhysicalAddress).WithMany().HasForeignKey(fk => fk.PhysicalAddressId);
}

public AddressMapping()
{
    ToTable("Address");
    HasKey(pk => pk.AddressId);
    Property(pr => pr.AddressId).HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
}

@H_404_5@当我尝试运行update-database时,我得到：

@H_404_5@

@H_404_5@Introducing FOREIGN KEY constraint
‘FK_dbo.UserProfile_dbo.Address_PhysicalAddressId’ on table
‘UserProfile’ may cause cycles or multiple cascade paths. Specify ON
DELETE NO ACTION or ON UPDATE NO ACTION,or modify other FOREIGN KEY
constraints.

@H_404_5@我需要在Address对象上没有任何反向映射.
我还需要能够硬删除UserProfile对象,包括其子地址(其中只有两个地址表).

@H_404_5@我的问题是,我想要的是什么？如果是这样,我做错了什么？

@H_404_5@[编辑]
Address对象也用于UserCompany和Customer等对象.

解决方法

因为地址不是UserProfile的子节点,而只是关联,所以您不想使用级联删除： @H_404_5@

@H_404_5@

Hasrequired(a => a.PostalAdress)
    .WithMany()
    .HasForeignKey(fk => fk.PostalAddressId)
    .WillCascadeDelete(false);
