asp.net mvc automapper using

recently i've started to use viewmodels with automapper. the problem appeared immediately. for example, i have such classes:

public class Zone
{
    public int ZoneId;

    public string Title;

    public int BannersCount;
}

public class ZoneView
{
    public int ZoneId
    {
        get;
        set;
    }

    public string Title;
    {
        get;
        set;
    }

    [Required(ErrorMessage = "Поле Кол-во баннеров является обязательным.")]
    [Display(Name = "Кол-во баннеров*")]
    public int BannersCount
    {
        get;
        set;
    }
}

and i don't want to edit Title in my view. so there i show Title not in TextEditor but so:

@Model.Title

and then in my POST action ZoneView comes with empty Title:

public ActionResult Edit(ZoneView zoneView)

after this i map it to domain model:

var zone = zonesRepository.Get(zoneView.ZoneId);
Mapper.Map<ZoneView, Zone>(zoneView, zone);

and after this in zone there is empty Title. What is the best way to act in this case?

  • Most of the time i use Hidden input such values.
  • And also check at DB level for validation of value with title.

This might not best solution but it works.

You can create a mapping definition, instructing automapper to ignore the Title property when pushing values into Zone. 

Mapper.CreateMap<ZoneView, Zone>()
   .ForMember(destination => destination.Title, member => member.Ignore());

You will define this CreateMap once, at application start up. Then map as you have been.

var zone = zonesRepository.Get(zoneView.ZoneId);
Mapper.Map<ZoneView, Zone>(zoneView, zone);
