How to add a new M-N relation in an Extended non-Abstract Entity? #8943

Hi, I have extended a non-abstract entity "OrganizationUnits" and created "OrganizationUnitGT". It works fine adding new parameters such as "ExternalCode". Now I want to add a new relation, it is an M-N relation with my Entity "TeleWorkingAudit". But I have the following problem:

"*The instance of entity type 'OrganizationUnitGT' cannot be tracked because another instance with the same key value for {'Id'} is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached. Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the conflicting key values.
System.InvalidOperationException: The instance of entity type 'OrganizationUnitGT' cannot be tracked because another instance with the same key value for {'Id'} is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached.Consider using 'DbContextOptionsBuilder.EnableSensitiveDataLogging' to see the conflicting key values.

Here I attach my code.

Entity - OrganizationUnitGT (extended from "OrganizationUnit")

namespace GenTime.Model
{
    /// <summary>
    /// Represents an extended organization unit in the system.
    /// </summary>
    public class OrganizationUnitGT : OrganizationUnit
    {
        public virtual string ExternalCode { get; set; }
        public ICollection<TeleWorkingAuditOrganizationUnitGT> TeleWorkingAuditOrganizationUnitGTs { get; set; }

        public OrganizationUnitGT()
        {
            TeleWorkingAuditOrganizationUnitGTs = new HashSet<TeleWorkingAuditOrganizationUnitGT>();
        }

    }
}

Entity - TeleWorkingAudit

namespace GenTime.Model
{
    public partial class TeleWorkingAudit : FullAuditedEntity, IMayHaveTenant
    {
        public TeleWorkingAudit()
        {
            TeleWorkingAuditApplications = new HashSet<TeleWorkingAuditApplication>();
            TeleWorkingAuditTeleWorkingControlGroups = new HashSet<TeleWorkingAuditTeleWorkingControlGroup>();
            TeleWorkingAuditUsers = new HashSet<TeleWorkingAuditUser>();
            TeleWorkingAuditOrganizationUnitGTs = new HashSet<TeleWorkingAuditOrganizationUnitGT>();
        }

        public int DesiredUse { get; set; }
        public int? RealUse { get; set; }
        public string DesiredTimeUse { get; set; }
        public long RealTimeUse { get; set; }
        public string UseTopDown { get; set; }

        public string FromHour { get; set; }
        public string ToHour { get; set; }
        public int[] DaySelected { get; set; }

        public int? TenantId { get; set; }

        public ICollection<TeleWorkingAuditApplication> TeleWorkingAuditApplications { get; set; }
        public ICollection<TeleWorkingAuditTeleWorkingControlGroup> TeleWorkingAuditTeleWorkingControlGroups { get; set; }
        public ICollection<TeleWorkingAuditUser> TeleWorkingAuditUsers { get; set; }
        public ICollection<TeleWorkingAuditOrganizationUnitGT> TeleWorkingAuditOrganizationUnitGTs { get; set; }
    }
}

MN Class - TeleWorkingAuditOrganizationUnitGT

namespace GenTime.Model
{
    public partial class TeleWorkingAuditOrganizationUnitGT
    {
        public int TeleWorkingAuditId { get; set; }
        public TeleWorkingAudit TeleWorkingAudit { get; set; }

        public long OrganizationUnitGTId { get; set; }
        public OrganizationUnitGT OrganizationUnitGT { get; set; }
    }
}

What am I doing wrong? What should modify or add?

Thanks in advance for your help.

    Hi,

    Could you also share your TeleWorkingAuditAppService.CreateAsync method ?

    Did you try to inherit TeleWorkingAuditOrganizationUnitGT from Entity class ?

    Hi,

    Add/Create m-n link ok.

            var organizationUnitListCall = await GetOrganizationUnits();
        var organizationUnitList = organizationUnitListCall.Items.ToList();
        for (int i = 0; i < input.OUs.Count; i++)
        {
            var organizationUnitDto = organizationUnitList.Where(x => x.Id == input.OUs[i]).FirstOrDefault();
            var organizationUnit = _objectMapper.Map<OrganizationUnitGT>(organizationUnitDto);
            organizationUnit.TenantId = teleWorkingAudit.TenantId;
            if (organizationUnit != null)
                teleWorkingAudit.TeleWorkingAuditOrganizationUnitGTs.Add(new TeleWorkingAuditOrganizationUnitGT() { OrganizationUnitGT = organizationUnit, OrganizationUnitGTId = organizationUnit.Id });
        }

    ----> the error is here, when everything is saved

        await _teleWorkingAuditRepository.InsertOrUpdateAsync(teleWorkingAudit);

    Hi,

    Could you check the value of Id field for organizationUnit in below line for each item ? Is it 0 or different all the time ?

    var organizationUnit = _objectMapper.Map<OrganizationUnitGT>(organizationUnitDto);

    Hi,

    Then, it seems fine. Could you add code below to your DbContext class to see the detailed error message and conflicting key ?

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder.EnableSensitiveDataLogging();
    // ...
}
