I am making an update API Call, but its updating CreationTime and CreatorUserId columns even If I'm not passing these values.
{
"testCode": "string",
"testName": "string",
"testDesc": "string",
"id": 1
}
public async Task UpdateTest(TestDetailsDTO input)
{
var classobj = ObjectMapper.Map<Test>(input);
await UpdateAsync(classobj);
}
public class TaxJurisdictionDetailsDTO : FullAuditedEntityDto
{
public string JurisdictionCode { get; set; }
public string JurisdictionName { get; set; }
public string JurisdictionDesc { get; set; }
}
Parameter input gets CreationTime in UpdateTest service method.

Hi @ManojReddy,
if you use mapper like following, a new object is creating. So all of properties are changing.
var classobj = ObjectMapper.Map<Test>(input);if you want to update entity, first you get the entity from database, and map it from dto like following.
var classobj = _someService.GetEntity(input.id); ObjectMapper.Map(input, classobj ); -

Thanks for your response.
But in this case it will make extra DB call by calling GetEntity method. Don't we have any alternative approach?

When you select entity from DB, EF can track this entity, if you want to do this manually, you should attach the entity to dbContext. For examlple;
// Create new stub with correct id and attach to context. var entity = new myEntity { Id = input.Id }; db.SomeEntities.Attach(entity); // Now the entity is being tracked by EF, update required properties. entity.Title = "new title"; entity.Url = "new-url"; // EF knows only to update the propeties specified above. db.SaveChanges();To do this in aspnet zero, you should change repositorybase or you can write a custom repository.

Following code is not working, Its updating CreationTime, CreatorUserId.
var classobj = _someService.GetEntity(input.id); ObjectMapper.Map(input, classobj ); -

Remove CreationTime and CreatorUserId from TestDetailsDto.
If you want a workaround:
var classobj = _someService.GetEntity(input.id); input.CreationTime = classobj.CreationTime; input.CreatorUserId = classobj.CreatorUserId; ObjectMapper.Map(input, classobj);
