In an ASP.NET Core 1.1 Web API, I am trying to map an entity model to a DTO using AutoMapper.
The entity model:
namespace InspectionsData.Models
{
[Table("property")]
public class Property
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
[Column("property_id")]
public int? Id { get; set; }
[Column("show_inventory")]
public bool ShowInventory { get; set; }
[Column("latitude")]
public double? Latitude { get; set; }
[Column("longitude")]
public double? Longitude { get; set; }
[Column("property_type_id")]
public int? PropertyTypeId { get; set; }
[ForeignKey("PropertyTypeId")]
[Display(Name = "Property Type")]
public PropertyType PropertyType { get; set; }
[Column("inspection_frequency_id")]
public int? InspectionFrequencyId { get; set; }
[ForeignKey("InspectionFrequencyId")]
[Display(Name = "Inspection Frequency")]
public InspectionFrequency InspectionFrequency { get; set; }
[Column("group_id")]
public int? GroupId { get; set; }
[ForeignKey("GroupId")]
[Display(Name = "Group")]
public Group Group { get; set; }
[Column("added_by_id")]
public int? AddedById { get; set; }
[ForeignKey("AddedById")]
[Display(Name = "Added By")]
public virtual User AddedBy { get; set; }
[Column("added_date")]
[Display(Name = "Added Date")]
public DateTime AddedDate { get; set; }
[Column("deleted_by_id")]
public int? DeletedById { get; set; }
[ForeignKey("DeletedById")]
[Display(Name = "Deleted By")]
public virtual User DeletedBy { get; set; }
[Column("deleted_date")]
[Display(Name = "Deleted Date")]
public DateTime? DeletedDate { get; set; }
}
and the DTO:
namespace InspectionsData.DTOs
{
public class PropertyDto
{
public int? Id { get; set; }
public bool ShowInventory { get; set; }
public double? Latitude { get; set; }
public double? Longitude { get; set; }
public PropertyType PropertyType { get; set; }
public InspectionFrequency InspectionFrequency { get; set; }
public DateTime NextInspectionDate { get; set; }
}
}
The mapping is done in a configuration file:
public class AutoMapperProfileConfiguration : Profile
{
public AutoMapperProfileConfiguration()
{
// Add as many of these lines as you need to map your objects
var map = CreateMap<Property, PropertyDto>();
map.ForAllMembers(opt => opt.Ignore());
map.ForMember(dest => dest.Id, opt => opt.MapFrom(src => src.Id));
map.ForMember(dest => dest.ShowInventory, opt => opt.MapFrom(src => src.ShowInventory));
map.ForMember(dest => dest.Latitude, opt => opt.MapFrom(src => src.Latitude));
map.ForMember(dest => dest.Longitude, opt => opt.MapFrom(src => src.Longitude));
map.ForMember(dest => dest.PropertyType, opt => opt.MapFrom(src => src.PropertyType));
map.ForMember(dest => dest.InspectionFrequency, opt => opt.MapFrom(src => src.InspectionFrequency));
}
}
And the setting up of AutoMapper in Startup.cs:
public void ConfigureServices(IServiceCollection services)
{
var config = new AutoMapper.MapperConfiguration(cfg =>
{
cfg.AddProfile(new AutoMapperProfileConfiguration());
});
var mapper = config.CreateMapper();
services.AddSingleton(mapper);
}
In my controller action, I execute the mapping:
[HttpGet]
public async Task<IActionResult> GetProperty()
{
var properties = _context.Property
.Include(t => t.PropertyType)
.Include(f => f.InspectionFrequency)
.Where(a => a.DeletedDate == null && a.GroupId == 1);
var propertiesDto = _mapper.Map<IEnumerable<PropertyDto>>(properties);
return Ok(propertiesDto);
}
It doesn't give an error, but all the properties in all the objects in the propertiesDto list are default values (NULL for objects and nullable types, FALSE for booleans, 0 for integers, etc.) Any ideas where I'm going wrong?
It's because the following line
map.ForAllMembers(opt => opt.Ignore());
is letting AM ignore all member mappings, including the ones you have configured explicitly.
Simply use ForAllOtherMembers
instead:
map.ForAllOtherMembers(opt => opt.Ignore());
