通过流畅的nhibernate映射类和子类 [英] Mapping of classes and sub classes by fluent nhibernate

问题描述

朋友们，



我在映射模型类时遇到问题（带子类）。

我没有得到名字。它在编写代码时显示错误。

错误是CatsTute不包含'Name'的定义，并且没有扩展方法'Name'可以找到接受'CatsTute'类型的第一个参数（你是否缺少using指令或汇编参考？）：

这是主模型（CatsTutes）：

hi friends,

I am getting problem while mapping my model class(with subclasses).
I am not getting the Name. It shows error while writing the code.
The error is "CatsTute' does not contain a definition for 'Name' and no extension method 'Name' accepting a first argument of type 'CatsTute' could be found (are you missing a using directive or an assembly reference?)":
Here is main model (CatsTutes):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using codes.Models.BaseModel;

namespace codes.Models
{
    public class CatsTute:ModelBase
    {
        public class Category:ModelBase
        {
            public virtual string Name { get; set; }
            public virtual string Image { get; set; }
        }
        public class SubCat:ModelBase
        {
            public virtual int CatId { get; set; }
            public virtual string Name { get; set; }
            public virtual string Image { get; set; }
        }
        public class Tutorial:ModelBase
        {
            public virtual string Name { get; set; }
            public virtual string Description { get; set; }
            public virtual int SubCatId { get; set; }
        }
    }
}

这是基本型号（ModelBase）： -

This is base model(ModelBase):-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace codes.Models.BaseModel
{
    public class ModelBase
    {
        public virtual int Id { get; set; }
        public virtual DateTime CreatedOn { get; set; }
        public virtual DateTime UpdatedOn { get; set; }
        public virtual int Deleted { get; set; }
        public virtual bool Status { get; set; }
    }
}

这是映射类（AllMapping）： -

Here is mapping class(AllMapping):-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using FluentNHibernate.Mapping;

namespace codes.Models.Mapping
{
    public class AllMappings : ClassMap<CatsTute>
    {
        public AllMappings()
        {
            Table("CatsTute");
            Id(x => x.Id, "Id").GeneratedBy.Identity().UnsavedValue(0);
            Map(x => x.Status);
            Map(x => x.CreatedOn);
            Map(x => x.UpdatedOn);
            Map(x => x.Deleted);
            Map(x => x.Name).CustomSqlType("nvarchar(50)");   <========Here is the problem
            DynamicUpdate();
        }
    }
}

我尝试了什么：



我不知道该怎么做............

推荐答案

在我看来，' Name '被定义了三次，所以也许你需要使用像 Name1，Name2，Name3这样的唯一名称。

这是一篇关于CodeProject的文章，它解释了映射子类： Fluent Nhibernate中的继承映射策略 [ ^ ]

The problem seems to me that 'Name' is defined three times, so maybe you need to use unique names like Name1, Name2, Name3.
Here is an article on CodeProject which explains mapping subclasses: Inheritance mapping strategies in Fluent Nhibernate[^]
