c# - Mapping db view without Id to class model in NHibernate -

in application, use nhibernate orm , automapper mapping entities class model. as: fluent-nhibernate/wiki/auto-mapping

for tables working.

problem when try mapping db view without id field, like:

public class vtest {      [notnull]     public virtual aaatab aaa { get; set; }     [notnull]     public virtual bbbtab bbb { get; set; } 

}

i create composite key :

public void override(automapping<vtest> mapping)     {         mapping.ignoreproperty(x => x.id);         mapping.compositeid()                 .keyproperty(x => x.aaa.id)                .keyproperty(x => x.bbb.id);     } 

but not working. error, becouse in db query have select id :

[genericadoexception: not execute query [ select this_.id id7_0_, this_.aaaid aaaid7_0_, this_.bbbid bbb_7_0_ [vtest] this_ ]

its possible use automapper case?

i find solutions. in compositekey must use phisical exist property in db view, create new properties:

public virtual int aaaid {get;set;} public virtual int bbbid {get;set;} 

and create:

    mapping.ignoreproperty(x => x.id);     mapping.compositeid()            .keyproperty(x => x.aaaid)            .keyproperty(x => x.bbbid); 

this automapping view or table without id works. (to model dbview or table, need add override function equals() , gethashcode() )
