Question

您好我有一个名为document的对象和一个名为user

的对象

文档

    public virtual string Name { get; set; }
    public virtual string Description { get; set; }
    public virtual User User { get; set; }

Documentmap

    public DocumentMap()
    {
        Map(x => x.Name);
        Map(x => x.Description);
        References(x => x.User);
    }

用户

    public virtual string UserId { get; set; }
    public virtual string FirstName { get; set; }
    public virtual string MiddleInitial { get; set; }
    public virtual string LastName { get; set; }
    private readonly IList<Document> _documents = new List<Document>();
    public virtual IEnumerable<Document> Documents { get { return _documents; } }
    public virtual void Remove(Document document)
    {
        _documents.Remove(document);
    }
    public virtual void Add(Document document)
    {
        if (!document.IsNew() && _documents.Contains(document)) return;
        _documents.Add(document);
    }

    Map(x => x.UserId);
        Map(x => x.FirstName);
        Map(x => x.MiddleInitial);
        Map(x => x.LastName);
        HasMany(x => x.Documents).Access.CamelCaseField(Prefix.Underscore);

相当直接（他们从诸如createddate modifieddate之类的东西继承基类）

当我尝试通过用户ID获取所有文档时，我得到了这个

无效的列名称'UserId'。

列绝对是在表中。它还列出了几个不存在的基类项目。

我接受sql并在查询管理器中将其过去，我得到intellisense，说它们是无效的列。我运行它，它执行得很好。还有更多使用这些基类的其他对象没有问题。

我尝试了各种各样的事情，比如显式映射键名，使用inverse等列名无效。真的不知道该怎么做。谢谢， RAIF

//根据请求编辑对不起，它太冗长了。数据库由nhibernate create schema

创建

文档

public class Document : Entity
{
    public virtual string Name { get; set; }
    public virtual string Description { get; set; }
    public virtual DocumentCategory DocumentCategory { get; set; }
    [ValueOf(typeof(DocumentFileType))]
    public virtual string FileType { get; set; }
    public virtual string FileUrl { get; set; }
    public virtual int? Pages { get; set; }
    public virtual decimal? Size { get; set; }
    public virtual User User { get; set; }
}

public class DocumentMap : EntityMap<Document>
{
    public DocumentMap()
    {
        Map(x => x.Name);
        Map(x => x.Description);
        Map(x => x.FileUrl);
        Map(x => x.Pages);
        Map(x => x.Size);
        Map(x => x.FileType);
        References(x => x.DocumentCategory);
        References(x => x.User);
    }
}

实体

public class Entity : IGridEnabledClass, IEquatable<Entity>
{
    public virtual int EntityId { get; set; }
    public virtual DateTime? CreateDate { get; set; }
    public virtual DateTime? ChangeDate { get; set; }
    public virtual int ChangedBy { get; set; }
    public virtual bool Archived { get; set; }

    public virtual bool IsNew()
    {
        return EntityId == 0;
    }

用户

 public class User : DomainEntity, IUser
{
    public virtual string UserId { get; set; }
    [ValidateNonEmpty]
    public virtual string FirstName { get; set; }
    public virtual string MiddleInitial { get; set; }
    [ValidateNonEmpty]
    public virtual string LastName { get; set; }
    public virtual string Title { get; set; }
    public virtual DateTime? BirthDate { get; set; }
    public virtual string StartPage { get; set; }
    public virtual UserLoginInfo UserLoginInfo { get; set; }
    public virtual UserStatus UserStatus { get; set; }
    public virtual Photo HeadShot { get; set; }
    private readonly IList<Document> _documents = new List<Document>();
    public virtual IEnumerable<Document> Documents { get { return _documents; } }
    public virtual void Remove(Document document)
    {
        _documents.Remove(document);
    }
    public virtual void Add(Document document)
    {
        if (!document.IsNew() && _documents.Contains(document)) return;
        _documents.Add(document);
    }
    several more collections

public class UserMap : DomainEntityMap<User>
{
    public UserMap()
    {
        Map(x => x.UserId);
        Map(x => x.FirstName);
        Map(x => x.MiddleInitial);
        Map(x => x.LastName);
        Map(x => x.BirthDate);
        Map(x => x.StartPage);
        References(x => x.UserStatus);
        References(x => x.UserLoginInfo);
        References(x => x.HeadShot);
        HasMany(x => x.Documents).Access.CamelCaseField(Prefix.Underscore);

数据库表从脚本选择创建到管理工作室的菜单项

  SELECT [EntityId]
  ,[CreateDate]
  ,[ChangeDate]
  ,[ChangedBy]
  ,[Archived]
  ,[Name]
  ,[Description]
  ,[FileUrl]
  ,[Pages]
  ,[Size]
  ,[FileType]
  ,[DocumentCategoryId]
  ,[UserId]
  FROM [DecisionCriticalSuite].[dbo].[Document]
 GO


  SELECT [EntityId]
  ,[CreateDate]
  ,[ChangeDate]
  ,[ChangedBy]
  ,[Archived]
  ,[TenantId]
  ,[OrgId]

Answer 1

确保nhibernate正在查询与您在sql management studio中查询的数据库相同的数据库。

Answer 2

我遇到了同样的问题，因为我已经将 Entity1.Entity2 映射为Entity3。

因此，在加入时，它将尝试使用Entity3中的属性，就像它存在于Entity2上一样。

当列存在时，Nhibernate错误'列名无效'
