城堡Activerecord。两个同一类的集合

Question

我想在Activerecord中有两个相同类项的集合。 如何映射？

class Project
{
 [HasMany]
 IList<Resource> Resources { get; set; }

 [HasMany]
 IList<Resource> DepartmentResources { get; set; }
}

public class Resource
{
 [BelongsTo ???
}

Answer 1

使用ColumnKey属性，例如：

[HasMany(ColumnKey="res")]
IList<Resource> Resources { get; set; }

[HasMany(ColumnKey="deptres")]
IList<Resource> DepartmentResources { get; set; }

...

public class Resource {
  [BelongsTo("res")]
  Project Project {get;set;}

  [BelongsTo("deptres")]
  Project DeptProject {get;set;}
}
