【问题描述】:
我正在尝试映射这些实体:
[Table("AAN_DigitalLib_Asset")]
public class Asset
{
[Column("ID")]
public int ID { get; set; }
[Column("format_id")]
public int FormatID { get; set; }
[Column("person_id")]
public int? PersonID { get; set; }
[Column("publicationYear")]
public int? PublicationYear { get; set; }
public Person People { get; set; }
//public virtual AssetKeyword AssetKeywords { get; set; }
public virtual ICollection<AssetKeyword> AssetKeywords { get; set; }
}
使用这些实体:
[Table("AAN_DigitalLib_AssetKeyword")]
public class AssetKeyword
{
[Column("ID")]
public int ID { get; set; }
[Column("asset_id")]
public int AssetID { get; set; }
[Column("keyword")]
public string Keyword { get; set; }
}
单个Asset 可以有多个AssetKeywords。数据库中没有指定关系,如何使用 Fluent API 创建关系?
