本文介绍了CTP5:还是自我引用问题?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

有一个简单的模型:

   公共类节点

    {

        public long Id {get;组; }
        public virtual Node Parent {get;组; }
    }

    public class Node
    {
        public long Id { get; set; }
        public virtual Node Parent { get; set; }
    }

以下地图代码将引发异常:

the following map code will throw an exception:

    public class NodeContext:DbContext

    {

        public DbSet< Node>节点{get;组; }


        protected override void OnModelCreating(ModelBuilder modelBuilder)

        {

            base.OnModelCreating(modelBuilder);

    public class NodeContext : DbContext
    {
        public DbSet<Node> Nodes { get; set; }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);

            modelBuilder.Entity< Node>()。HasOptional(n => n.Parent).WithMany()。IsIndependent()。Map(m => m.MapKey(p => p.Id," ParentId" ));

            modelBuilder.Entity<Node>().HasOptional(n => n.Parent).WithMany().IsIndependent().Map(m => m.MapKey(p => p.Id, "ParentId"));

        }
    }

        }
    }

可能是因为它无法自我引用自定义外键名称吗?是吗?

推荐答案

我有类似的东西

刚丢失 

。地图(m => m.MapKey(p => p.Id," ParentId")))
部分

...建筑似乎有一些问题,所以我认为它确实没有用。

你可能会得到NodeId而不是parentId,没关系多少b $ b希望它有帮助

I have something similar
just lose the 
.Map(m => m.MapKey(p => p.Id, "ParentId"))
part
...that construction seems to have some problems, so I don't think it works really.
You'll probably get NodeId instead of parentId, doesn't matter much
hope it helps
