c# - One-Many via NHibernate Loquacious mapping by code or xml -

i want implement one-to-many relationship between person , car, , have crud operations on both person , car. brief crud , relationships:

update

• a person has many cars
• crud operations on both person , car via person object.
• deleting person delete s/his cars
• ability perform crud operation on someone's cars, either via person object or car object.

is possible via orm, in particular nhibernate?

classes below:

public class personset {     public virtual int id { get; set; }     public virtual string name { get; set; }     public virtual iset<carset> cars { get; set; } }  public class carset {     public virtual int id { get; set; }     public virtual string name { get; set; }     public virtual personset person { get; set; } } 

mapping shown below:

  public class personsetmap : classmapping<personset>     {         public personsetmap()         {             id(x => x.id, m=>m.generator(generators.identity));             property(x=>x.name);             set(x => x.cars, c =>                 {                     //c.key(k =>                     //    {                     //        k.column("personid");                     //    });                      c.cascade(cascade.all);                     c.lazy(collectionlazy.nolazy);                    // c.inverse(true);                 }                 , r =>                     {                         r.onetomany();                     }                 );         }     }      public class carsetmap : classmapping<carset>     {         public carsetmap()         {             id(x => x.id, m => m.generator(generators.identity));             property(x => x.name);             manytoone(x => x.person, m =>             {                 m.column("personid");                 m.cascade(cascade.none);                 m.notnullable(true);             });          }     } 

the problem have if update 1 car , try save on person object, doesn't change.

update

i want find out if possible, , mapping above wrong. idea on either xml version or loquacious appreciated.

there should personid foreign key on table car.

i don't know if solve problem, in manytoone mapping unique , notnullable methods should applied @ column level.

manytoone(x => x.person, m => {     m.column(c =>     {         c.name("personid");         c.notnullable(true);     });     m.cascade(cascade.none); });
