[英]Same table NHibernate mapping
How can i go about defining a same table relation mapping (mappingbycode) using Nhibernate 如何使用Nhibernate定义相同的表关系映射(mappingbycode)
for instance let's say I have a class: 例如,假设我有一堂课:
public class Structure{
public int structureId;
public string structureName;
public Structure rootStructure;
}
that references the same class as rootStructure. 引用与rootStructure相同的类。
mapper.Class<Structure>(m =>
{
m.Lazy(true);
m.Id(u => u.structureId, map => { map.Generator(Generators.Identity); });
m.Property(c => c.structureName);
m.? // Same table mapping
}
;
Thanks 谢谢
there is no special mapping for recursive mappings i am aware of. 我知道递归映射没有特殊的映射。 Just map it like you would map a collection of a different class.
就像映射一个不同类的集合一样映射它即可。 In your case this should work (untested though):
在您的情况下,这应该可以工作(尽管尚未试用):
m.OneToOne(c => c.rootStructure, a => a.Lazy(LazyRelation.Proxy))
NHibernate will assume that the foreign key for this relation is stored on column rootStructure of the table associated to that class. NHibernate将假定此关系的外键存储在与该类关联的表的rootStructure列上。
