Why does it create an Id field in the database again in C# coding?-CodePudding

My bll codes:

        {
            return BaseList(filter, x => new KasaL
            {
                Id = x.Id,
                Kod = x.Kod,
                KasaAdi = x.KasaAdi,
                OzelKod1Adi = x.OzelKod1.OzelKodAdi,
                OzelKod2Adi = x.OzelKod2.OzelKodAdi,
                Aciklama = x.Aciklama,
                BelgeNo=x.BelgeNo,
                BenzersizKod=x.BenzersizKod,

                Borc = x.KasaHareket.Where(y => y.KasaId == x.Id).GroupBy(y => y.KasaId).DefaultIfEmpty().Select(z => new { Borc = z.Select(a => a.Borc).DefaultIfEmpty(0).Sum() }).FirstOrDefault().Borc,
                Alacak = x.KasaHareket.Where(y => y.KasaId == x.Id).GroupBy(y => y.KasaId).DefaultIfEmpty().Select(z => new { Alacak = z.Select(a => a.Alacak).DefaultIfEmpty(0).Sum() }).FirstOrDefault().Alacak,

            }).OrderBy(x => x.Kod).ToList();
        }

My DTO Codes:

public class KasaL : BaseEntity
    {
        public string KasaAdi { get; set; }
        public string OzelKod1Adi { get; set; }
        public string OzelKod2Adi { get; set; }
        public string Aciklama { get; set; }
        public decimal Borc { get; set; } = 0;
        public decimal Alacak { get; set; } = 0;
        public decimal Bakiye { get; set; } = 0;

    }

My Entity Kasa Codes:

   public class Kasa : BaseEntityDurum
    {
        [Index("IX_Kod", IsUnique = false)]
        public override string Kod { get; set; }

        public OzelKod OzelKod2 { get; set; }
        public List<KasaHareket> KasaHareket { get; set; }
    }

My KasaHareket entity code:

When the migration is done, the Kasa_Id field is created automatically. When this field is created, collection operations are not performed.

The Kasa_Id field is created automatically. This area should not exist.

Can you help me?

CodePudding user response：

Do you have a property defined in of the base classes I.e. BaseEntity or BaseEnityDurum that has a byte field and/or a [Key] attribute Data Annotation in it /

CodePudding user response：

You may need to clarify which table/entity you are seeing the extra ID in. I'm assuming your "BaseEntityDurum" class has:

[Key]
long Id {get; set;}

declared?

One issue I see if you are referring to the KasaHareket table/entity:

    public Kasa Kasa { get; set; }
    public Kasa Kasa2 { get; set; }

While you do have:

    public long KasaId { get; set; }
    public long? Kasa2Id { get; set; }

You are not nominating these as Foreign Keys. EF's default convention is to name FKs based on the type rather than the property name. So with two references to a Kasa entity it would typically use "Kasa_Id" and "Kasa_Id2". It may have auto-resolved "KasaId" from your entity, but then when it went to map Kasa2, it opted to generate "Kasa_Id".

Try updating the Kasa references to nominate the FKs:

[ForeignKey("KasaId")]
public Kasa Kasa { get; set; }
[ForeignKey("Kasa2Id")]
public Kasa Kasa2 { get; set; }
