Dear support, I am injecting objects through an IRepository, and the CreatorUserId is filled with my current UserId = 2 (auto detected by ABPSession) when inserted into DB.
I want to modify the UserId of the object, to set it to null. Following your documentation, I use the session.Use (allowing a "long?" parameter) method but when I set the 2nd parameter as null, the UserId is still equals to "2".
If I use a non null value (e.g. "10"), this new value will correctly inserted into db.
Is there any info related to the null, that I am not aware of ?
public void InsertOrUpdateAreas(IList areas)
{
using (_session.Use(_session.TenantId, null))
{
var tenantId = _session.TenantId; //2
var userId = _session.UserId; //2 ==> abp gives "2" instead of null
foreach (var area in areas)
_areaRepository.Insert(area);
CurrentUnitOfWork.SaveChanges();
}
}

Hi @daws
UserId for audit fields is retrieved using this method https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp.EntityFrameworkCore/EntityFrameworkCore/AbpDbContext.cs#L492. You can override it in your DbContext and allow null values. By default, it doesn't allow null values.

Thanks for the hint but I am still stuck.
If I override GetAuditUserId, of course I can force it to return null but I want to get a null value only in a specific call, not for all methods. In all other method (except the one listed in my other post), it is important to keep the UserId filled in.
thus, I wanted to use this function https://github.com/aspnetboilerplate/aspnetboilerplate/blob/dev/src/Abp/Runtime/Session/AbpSessionBase.cs#L40 which is supposed to take nullable userId but which does not work.
I halso have another possibility which is to give a boolean parameter to the dbcontext
TestDbContext : AbpZeroDbContextonce the program is started and, depending of this boolean parameter, returning null in GetAuditUserId(). But I can not find a way to give a parameter to the dbcontext when it is created.do you have any more tips ?
thanks
protected override long? GetAuditUserId() { if (AbpSession.UserId.HasValue && CurrentUnitOfWorkProvider != null && CurrentUnitOfWorkProvider.Current != null && CurrentUnitOfWorkProvider.Current.GetTenantId() == AbpSession.TenantId) { return AbpSession.UserId; } return null; } -

Hi @daws
Maybe you can set a parameter in HttpContext and return null only when that parameter is set. In that way, you can return null only for specific calls.

modifing the httpcontext or overriding the abpsession was too much complex for my use case.
I have found the solution, simply use
using (_unitOfWorkManager.Current.DisableAuditing(new string[]{ AbpAuditFields.CreationUserId}))
