I am trying to insert value in DateTime column with Entity Framework but it throwing error on db.SaveChanges() function. There are 2 DateTime columns but exception throwing for only one (entry.OT_Date) with no maximum detail.
var entry = new OT_Request_N();
entry.Emp_ID = StaticFunctions.WindowUserId;
entry.slno = db.OT_Request_N.Max(x=>x.slno)+1;
entry.OT_Date= otD;
entry.OT_Time_Req = hourRequest;
entry.Remarks_Req = sError.ReqRemarks;
entry.Req_Sent_On = DateTime.Now;
entry.Supervisor_ID = sError.ManagerID;
entry.Approve_Status = 0;
db.OT_Request_N.Add(entry);
db.SaveChanges();
Here is SQL table Design
Here is class generated in edmx file
public partial class OT_Request_N
{
public int slno { get; set; }
public string Emp_ID { get; set; }
public Nullable<System.DateTime> Req_Sent_On { get; set; }
public Nullable<int> OT_Time_Req { get; set; }
public string Supervisor_ID { get; set; }
public string Remarks_Req { get; set; }
public string Remarks_App { get; set; }
public Nullable<int> OT_Time_App { get; set; }
public string Approved_By { get; set; }
public Nullable<int> Approve_Status { get; set; }
public Nullable<System.DateTime> Approved_On { get; set; }
public Nullable<int> Operations { get; set; }
public string AltReq_ID { get; set; }
public Nullable<bool> Is_alert_sent { get; set; }
public Nullable<System.DateTime> OT_Date { get; set; }
}
This is my error :
Unable to determine the principal end of an association between the types 'SANTEK.Web.Models.SantekOrder' and 'SANTEK.Web.Models.OrderMoneySum'. The principal end of this association must be explicitly configured using either the relationship fluent API or data annotations.
What is my mistake logically ?? I mean to build one-to-one relation.
My model classes are here :
[Table("Orders")]
public class SantekOrder
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int SantekOrderId { get; set; }
[Required, StringLength(25)]
[DisplayName("Çatdırılacaq şəxs")]

public virtual SanTekUser SanUser { get; set; }
[ForeignKey("SanTekUserId")]
public virtual OrderMoneySum OrderMoneySum { get; set; }
}
This is my OrdersDetail Table to hold all product and their quantity
[Table("OrderedProducts")]
public class OrderMoneySum
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int OrderMoneySumId { get; set; }
[Required]
public int SantekOrderId { get; set; }

}
I have a situation with data field validation in MVC 4
this is my Model
public class Purchase
{
public Purchase()
{
PurchaseDetails = new List<PurchaseDetails>();
}
public int PurchaseID { get; set; }
[DisplayName("Compra N°")]
[Required]
public int PurchaseNumber { get; set; }
[DisplayName("Anulada")]
[Required]
public bool isAnulada { get; set; }
public int ProviderID { get; set; }
public virtual Provider Provider { get; set; }
[DisplayName("Nombres/Notas")]
[Required]
public string Notes { get; set; }
[DisplayName("Detalles de Compra")]
public string ProposalDetails { get; set; }
[DataType(DataType.Date), DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
[DisplayName("Creado")]
public DateTime TimeStamp { get; set; }
[DataType(DataType.Date), DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
[DisplayName("Pagado en Fecha")]
public DateTime PaidDate { get; set; }
[DisplayName("Impuesto a la Compra")]
[Range(0.00, 100.0, ErrorMessage = "Valor debe estar expresado en % Entre 0 y 100")]
public decimal AdvancePaymentTax { get; set; }
[DisplayName("Pagada")]
[Required]
public bool Paid { get; set; }
public virtual ICollection<PurchaseDetails> PurchaseDetails { get; set; }
}
When try Post or Create my purchase raise the error "The Field must be a Date" i don't know how, this malfunction appear in IExplorer an Chrome browser
Any Idea? Thanks for the answer....

You're returning JoomlaWebservice.KundeService.Opgave, not JoomlaWebservice.Opgave. You need to change your code to either return the contract directly or to map between your created object and the contract.
I have three model classes and three views. Models are given below
