I am using ASP.NET Core Web API. I have these models:
public abstract class EntityBase
{
[Key]
public int Id { get; set; }
}
public class Mandate : EntityBase
{
public DateTime DueDate { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public virtual TransactionLog TransactionLog { get; set; }
}
public class TransactionLog
{
[Key, ForeignKey("Mandate")]
public int? MandateId { get; set; }
public string RawData { get; set; }
public virtual Mandate Mandate { get; set; }
}
Models: Mandate and TransactionLog
Mandate has one-to-one relationship with TransactionLog
Mandate Table
- Id
- DueDate
- StartDate
- EndDate
TransactionLog
- MandateId (Key)
- RawData
ViewModel (Dto):
public class MandateDto
{
public DateTime DueDate { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public int? MandateId { get; set; }
public string? RawData { get; set; }
}
EntityMapper:
public class EntityMapper
{
public Mandate FromMandateDtoToMandate(MandateDto mandate)
{
return new Mandate
{
DueDate = mandate.DueDate,
StartDate = mandate.StartDate,
EndDate = mandate.EndDate
};
}
public TransactionLog FromMandateDtoToTransactionLog(MandateDto mandate)
{
return new TransactionLog
{
RawData = ???,
};
}
}
MandateService:
public async Task<Mandate> Post(MandateDto mandate)
{
var mapper = new EntityMapper();
var mandate = mapper.FromMandateDtoToMandate(mandate);
var transaction = mapper.FromMandateDtoToTransactionLog(mandate);
try
{
await _unitOfWork.MandateRepository.Insert(mandate);
await _unitOfWork.TransactionRepository.Insert(transaction);
await _unitOfWork.SaveChangesAsync();
}
catch (Exception e)
{
throw new Exception(e.Message);
}
return mandate;
return transaction;
}
As explained earlier, Mandate has one-to-one relationship with TransactionLog. Since both Mandate and TransactionLog Data will be inserted at the same time, I want to automatically insert DueDate,StartDate, EndDate fron Mandate into RawData of TransactionLog as JSON RawData:
RawData = ???
How do I achieve this?
Thanks

You can use the JsonSerializer.Serialize
method from System.Text.Json
to do that.
