テーブル モデル:
public class UserOwnerShip
{
public virtual int Id { get; set; }
public virtual User User { get; set; }
public virtual City City { get; set; }
public virtual Company Company { get; set; }
public virtual UserRole UserRole { get; set; }
public virtual DateTime RegistryDate { get; set; }
public virtual bool IsActive { get; set; }
}
マッピング:
internal class UserOwnerShipMap : ClassMap<UserOwnerShip>
{
public UserOwnerShipMap()
{
Id(x => x.Id);
Map(x => x.IsActive);
Map(x => x.UserRole).CustomType(typeof(int));
Map(x => x.RegistryDate);
References(x => x.User).Not.Nullable();
References(x => x.City).Nullable();
References(x => x.Company).Nullable();
}
}
私のEnumConventionクラス:
public class EnumConvention : IUserTypeConvention
{
public void Accept(IAcceptanceCriteria<IPropertyInspector> criteria)
{
criteria.Expect(x => x.Property.PropertyType.IsEnum ||
(x.Property.PropertyType.IsGenericType &&
x.Property.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) &&
x.Property.PropertyType.GetGenericArguments()[0].IsEnum)
);
}
public void Apply(IPropertyInstance target)
{
target.CustomType(target.Property.PropertyType);
}
}
および UserRole Enum
public enum UserRole
{
User,
Operator,
Manager,
Manager,
Admin
}
そして、私の nhibernate 設定セクション:
....().Conventions.AddFromAssemblyOf<EnumConvention>())
だから私がクエリすると:
IList<UserOwnerShip> userOwnerShip = session.QueryOver<UserOwnerShip>()
.Where(u => u.UserRole == UserRole.Owner)
.Where(u => u.IsActive)
.List<UserOwnerShip>();
私は例外を得ました:
Type mismatch in NHibernate.Criterion.SimpleExpression: UserRole expected type System.Int32, actual type XXX.XXX.UserRole (which is enum type class)
