と競合Entity FrameworkのINSERT文の私は、次のクラスO.R.M. FOREIGN KEY制約例外
public class Employee
{
public Guid Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Gender { get; set; }
public int Salary { get; set; }
public string PhoneNumber { get; set; }
public Guid DepartmentId { get; set; }
public virtual Department Department { get; set; }
public int Deleted { get; set; }
public bool IsDeleted()
{
return this.Deleted == 1 ? true : false;
}
public void MarkAsDeleted()
{
this.Deleted = 1;
}
public string GetFullName()
{
return this.FirstName + " " + this.LastName;
}
}
public class Department
{
public Department()
{
this.Employees = new List<Employee>();
}
public Guid Id { get; set; }
public string Name { get; set; }
public virtual List<Employee> Employees { get; set; }
public int Deleted { get; set; }
public bool IsDeleted()
{
return this.Deleted == 1 ? true : false;
}
public void MarkAsDeleted()
{
this.Deleted = 1;
}
public void AddEmployee(Employee employee)
{
this.Employees.Add(employee);
}
public void RemoveEmployee(Employee employee)
{
this.Employees.Remove(employee);
}
}
を持っていると私は、1対多の関係を作成したいと私の構成では、私はこの
次のコードを持っています[modelBuilder.Entity<Department>()
.HasMany(l => l.Employees).
WithRequired(r => r.Department).
HasForeignKey(r => r.DepartmentId);
しかし、それはFOREIGN KEY制約と競合INSERT文
例外がスローされます\ FK_dbo.Employees_dbo.Depa rtments_DepartmentId。競合がデータベース\エンティティ\、テーブル\ dbo.Departments \、列IDで発生しました
誰でもお手伝いできますか?ありがとう
