Castle Active Record - 一对多关系

Question

我尝试在活动记录中创建多对多关系。

[ActiveRecord("Users")]
public class User : ActiveRecordBase<User>
{
    private IList<PhotoAlbum> _albums = new List<PhotoAlbum>();

    [PrimaryKey]
    public virtual int UserId { get; set; }

    [BelongsTo("ProfilId")]
    public virtual Profil Profil { get; set; }

    [HasMany(Inverse = false,Cascade = ManyRelationCascadeEnum.Delete)]
    public IList<PhotoAlbum> Album
    {
        get { return _albums; }
        set { _albums = value; }
    }

    [Property]
    public virtual string Nick { get; set; }

}

[ActiveRecord("Profiles")]
public class Profil : ActiveRecordBase<Profil>
{
    [PrimaryKey]
    public int ProfilId { get; set; }

    [Property]
    public int Age { get; set; }
    [Property]
    public int Sex { get; set; }
    [Property]
    public string Region { get; set; }
    [Property]
    public string Town { get; set; }
    [Property]
    public bool WithPhoto { get; set; }
    [Property]
    public bool HasPhotoAlbum { get; set; }
}

[ActiveRecord("PhotoAlbums")]
public class PhotoAlbum : ActiveRecordBase<PhotoAlbum>
{
    [PrimaryKey]
    public int PhotoAlbumId { get; set; }

    [Property]
    public string Name { get; set; }
    [Property]
    public int NumberOfPhoto { get; set; }
}

我正在使用 http://www.castleproject.org/activerecord/gettingstarted/relations 中的示例。 html

它完成时出现以下错误：

ActiveRecord 尝试推断有关 User.Album 关系的详细信息，但是 它无法在目标类型中找到“BelongsTo”映射属性

StrackTrace 中找到“BelongsTo”映射属性：

在 Castle.ActiveRecord.Framework.Internal.SemanticVerifierVisitor.VisitHasMany(HasManyModel 型号）在 Castle.ActiveRecord.Framework.Internal.HasManyModel.Accept(IVisitor 访客）在 Castle.ActiveRecord.Framework.Internal.AbstractDepthFirstVisitor.VisitNode(IVisitable 可访问）在 Castle.ActiveRecord.Framework.Internal.AbstractDepthFirstVisitor.VisitNodes(IEnumerable 节点）在 Castle.ActiveRecord.Framework.Internal.AbstractDepthFirstVisitor.VisitModel(ActiveRecordModel 型号）在 Castle.ActiveRecord.Framework.Internal.SemanticVerifierVisitor.VisitModel(ActiveRecordModel 型号）在 Castle.ActiveRecord.Framework.Internal.ActiveRecordModel.Accept(IVisitor 访客）在 Castle.ActiveRecord.Framework.Internal.AbstractDepthFirstVisitor.VisitNode(IVisitable 可访问）在 Castle.ActiveRecord.Framework.Internal.AbstractDepthFirstVisitor.VisitNodes(IEnumerable 节点）在 Castle.ActiveRecord.ActiveRecordStarter.RegisterTypes(ISessionFactoryHolder holder，IConfigurationSource 源，IEnumerable`1 类型，布尔值 忽略ProblematicTypes）在 Castle.ActiveRecord.ActiveRecordStarter.Initialize（IConfigurationSource 源，Type[] 类型）位于 SAMPLE_1.Program.Main(String[] args) 中 E:\C# PROJECTS\STUDY\STUDY.ORM\Active Record

SAMPLE_1.相册

我认为问题出在这里：

    [HasMany(Inverse = false,Cascade = ManyRelationCascadeEnum.Delete)]
    public IList<PhotoAlbum> Album
    {
        get { return _albums; }
        set { _albums = value; }
    }

如果我省略了这个属性/关系，它会很好地工作。

Answer 1

假设一个配置文件有许多相册，您的 PhotoAlbum 类缺少一个属性：

[BelongsTo("ProfileId")]
public Profile Profile { get; set; }
