创建一个 ActiveRecord 类，该类具有一个行为类似于枚举的字段（但是对另一个 ActiveRecord 类的引用）
抱歉标题很长，问题相当简单：
我有 2 个类，玩家和角色（它们是 activerecord 表）
class Player
{
...Various fields...
[BelongsTo("RoleId")]
public Role Role {get;set;}
}
class Role
{
...Various fields...
[Property]
public string Name {get;set;}
}
一个玩家只能有一个角色，但是（对我来说），角色是否有 0- 并不重要1-2-很多玩家，所以我想省略 HasMany 属性（我的例子很简单，但我的数据库比这个大得多）。角色的行为类似于用户定义的枚举，可以这样做吗？哪个是正确的方法？
编辑1： 如果我有类似的情况，但我需要一个角色仅属于一个玩家（onetoone），但我想再次省略“角色”类中的部分（因此角色对这个关联一无所知）怎么办？
Sorry for long title, the question is rather simple:
I have 2 classes, Player and Role (they are activerecord table)
class Player
{
...Various fields...
[BelongsTo("RoleId")]
public Role Role {get;set;}
}
class Role
{
...Various fields...
[Property]
public string Name {get;set;}
}
A Player, can have only one role, but (for me), it doesn't matter if Role has 0-1-2-many players, so I would like to omit HasMany attribute (my example is easy, but my database is much bigger than this). Role is behaving like a user-defined enum, is possible to do this? Which is the correct way?
Edit 1:
What if I have a similar situation but I need that a Role belogs only to one player (onetoone), but again I would like to omit the part from the "Role" class (so role doesn't know anything about this association)

如果您指定BelongsTo属性而不是HasMany属性，我想要的已经完成，角色是否有0-1-2多个玩家并不重要。
If you specify BelongsTo attribute and not HasMany attribute, what I want is already done, the Role doesn't matter if has 0-1-2-many players.
