AutoMapper 7.0.1
Found an interesting issue that I couldn't explain. When mapping the view model back to the DB entity object, the Id property is not mapped and is always 0, unless I explicitly set its MapFrom in the CreateMap definition.
In the database, the TimeDetail.Id column is an auto-increment column, but I don't see how automapper would know that...but that was the only reason I could think of. Plus, this is for instances of updating an existing TimeDetail.
Debugger showing Id is populated in viewModel:
Debugger showing entity object that was mapped from automapper with Id = 0:
Map expression:
var entity = Mapper.Map<TimeDetail>(viewModel);
DB Table class object:
public partial class TimeDetail
{
public int Id { get; set; }
....other columns
}
View Model:
public class TimeDetailsListViewModel
{
public int Id { get; set; }
... other columns
}
Map:
CreateMap<TimeDetailsListViewModel, TimeDetail>(MemberList.Destination).IgnoreAllVirtual()
.ForMember(dest => dest.Id, c => c.MapFrom(m => m.Id)) <---- Id is 0 if I don't explicitly set the map using this
.ForMember(dest => dest.StartDateTime, c => c.MapFrom(m => TimeUtilities.ConvertToUTCDateTime(m.StartDateTime).Value))
.ForMember(dest => dest.EndDateTime, c => c.MapFrom(m => TimeUtilities.ConvertToUTCDateTime(m.EndDateTime)))
;
IgnoreAllVirtual Extension Method:
public static class AutoMapperExtensions
{
public static IMappingExpression<TSource, TDestination>IgnoreAllVirtual<TSource, TDestination>(
this IMappingExpression<TSource, TDestination> expression)
{
var desType = typeof(TDestination);
foreach (var property in desType.GetProperties().Where(p =>
p.GetGetMethod().IsVirtual))
{
expression.ForMember(property.Name, opt => opt.Ignore());
}
return expression;
}
}
