I have the following scenario.
public class DictionaryEntity
{
public virtual string DictionaryName { get; set; }
public virtual IList<DictionaryRecordEntity> DictionaryRecord { get; set; }
}
public class DictionaryDto
{
public string DictionaryName { get; set; }
public IList<DictionaryRecordEntity> DictionaryRecord { get; set; }
}
I'm using Automapper and NHibernate. In NHibernate the DictionaryRecord property is marked as lazy loaded .
When I make the mapping from DictionaryEntity -> DictionaryDto , Automapper loads all my DictionaryRecords.
But I don't want this behavior, is there a way to configure the Automapper in order to don't resolve this property until I really access this property.
My workaround for this situation consists of splitting the DictionaryEntity in 2 classes and create a second Automapper mapping.
public class DictionaryDto
{
public string DictionaryName { get; set; }
}
public class DictionaryDtoFull : DictionaryDto
{
public IList<DictionaryRecordEntity> DictionaryRecord { get; set; }
}
and then in the code, depending on the need, call AutoMapper.Map appropriately.
return Mapper.Map<DictionaryDto>(dict);
return Mapper.Map<DictionaryDtoFull>(dict);
Does somebody have a better solution for my problem?
You must add a condition to validate if the collection is initialized to be mapped. You can read here more details: Automapper: Ignore on condition of .
AutoMapper.Mapper.CreateMap<DictionaryEntity, DictionaryDto>()
.ForMember(dest => dest.DictionaryRecord, opt => opt.PreCondition(source =>
NHibernateUtil.IsInitialized(source.DictionaryRecord)));
You could ignore the property, if this is of use?
AutoMapper.Mapper.CreateMap<DictionaryEntity, DictionaryDto>()
.ForMember(dest => dest.DictionaryRecord,
opts => opts.Ignore());
