Updating Database for first time, getting error - asp.net-mvc

I m building an mvc application, using EF code first. I m right at begning. here is code which is concerned with my problem.
Advertisement Model
[Key]
public virtual int ID { get; set; }
public virtual int UserID { get; set; }
public virtual int Cycles { get; set; }
public virtual decimal Cost { get; set; }
public string Name { get; set; }
public virtual List<AdDisplayTime> DispalyTime { get; set; }
public virtual DateTime CreateDate { get; set; }
public virtual DateTime UpdateDate { get; set; }
public virtual int UpdatedBy { get; set; }
public virtual bool FullScreen { get; set; }
AdDisplayTimes Model
[Key]
public virtual int ID { get; set; }
public virtual int AdID { get; set; }
public virtual string DisplayTime { get; set; }
Status Model
[Key]
public virtual int ID { get; set; }
public virtual string Name { get; set; }
Here is seed method in my migrations class
var adDisplayTimes = new List<AdDisplayTime>
{
new AdDisplayTime{AdID = 1,DisplayTime = "10:30"},
new AdDisplayTime{AdID = 1,DisplayTime = "10:40"},
new AdDisplayTime{AdID = 1,DisplayTime = "10:50"},
new AdDisplayTime{AdID = 1,DisplayTime = "11:00"}
};
context.Advertisements.AddOrUpdate(a => a.Name,
new Advertisement
{
Name = "Fisrt Ad",
OwnerID = 1,
Cycles = 125,
Cost = (decimal)234.45,
FileName = "test.jpg",
Tier = 1,
Path = "~/UploadedImages/Pending/test.jpg",
DispalyTime = adDisplayTimes,
CreateDate = DateTime.Now,
ValidFrom = DateTime.Now,
ValidTill = DateTime.Now.AddMonths(1),
FullScreen = true,
IsAdminAd = false,
Status = 1
}
);
context.AdDisplayTimes.AddOrUpdate(ad=>ad.AdID,
new AdDisplayTime { AdID = 1, DisplayTime = "10:30" },
new AdDisplayTime { AdID = 1, DisplayTime = "10:40" },
new AdDisplayTime { AdID = 1, DisplayTime = "10:50" },
new AdDisplayTime { AdID = 1, DisplayTime = "11:00" }
);
context.Statuses.AddOrUpdate(s=>s.Name,
new Status{Name = "Pending"},
new Status{Name = "Approved"},
new Status{Name = "Edited"},
new Status{Name = "Activated"},
new Status{Name = "DeActivated"}
);
When i run command "update-database" from package manager consol in Visual studio I get
this
update-database

Please help me solve this

if you check inner exception you can see this error
The conversion of a datetime2 data type to a datetime data
type resulted in an out-of-range value
and the common solution found in SO is defining DateTime column's data type as datetime2.you can do it with Data Annotation like :
[Column(TypeName="datetime2")]
and with Fluent Api like :
HasColumnType("datetime2")
hope this helps.

DbUpdateException when removing and saving changes in EF

I'm trying to delete a record in the database by simply using db.'table'.remove('object') but when calling db.SaveChanges() exception is thrown.
'An exception of type 'System.Data.Entity.Infrastructure.DbUpdateException' occurred in EntityFramework.dll but was not handled in user code'
My deleting method in controller
public ActionResult Delete(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
Customer customer = db.Customers.Find(id);
if (customer == null)
{
return HttpNotFound();
}
db.Customers.Remove(customer);
db.SaveChanges();
return RedirectToAction("Index");
}
Model:
public class Customer
{
[Key, ForeignKey("User")]
public int UserId { get; set; }
public string Email { get; set; }
public virtual CreditCard CreditCard { get; set; }
public virtual ShoppingCart ShoppingCart { get; set; }
public virtual List<Enquiry> Enquiries { get; set; }
public virtual List<Order> Orders { get; set; }
public virtual User User { get; set; }
}
public class User
{
[Key]
public int Id { set; get; }
public string Username { set; get; }
public string Password { set; get; }
public string FirstName { set; get; }
public string Surname { set; get; }
public virtual UserRole UserRole { get; set; }
}
public class ShoppingCart
{
[Key, ForeignKey("Customer")]
public int Id { get; set; }
public virtual List<CartItem> CartItems { get; set; }
public virtual Customer Customer { get; set; }
}

It seems you have another Table called dbo.ShoppingCarts about a Shopping Cart, which have one or more rows related to the Customer you are trying to delete.
So first you must delete the rows related to that customer an then you can delete the customer. That happens because the Customer id is foreign key in that other table.
If that is no exactly the case, please add your ShoppingCarts class to the question.

DbUpdateException unhandled when trying to save in POST method of Delivery and Order after editing respectively

I seem to be getting DbUpdateException error on db.SaveChanges() after I edit my Delivery or Order. I'm not sure why, it works fine for Create and Delete.
Am I missing something somewhere? The GET Edit methods work fine for both.
I get this exception error:
System.Data.Entity.Infrastructure.DbUpdateException was unhandled by

PLEASE NOTE: I didn't use ViewModels for Edit Order, only for Edit Delivery.
The important part of the error is
Message=The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value`.
Both Delivery and Order have a number of DateTime fields and at least one of them is not being set when you save so their values are 01/01/0001 (i.e. DateTime.MinValue), but your database table field is DATETIME which only has a year range of 1753-9999. To prevent the error, you can change the sql type to DATETIME2 which matches the c# DateTime range.
However, I suspect the real issue is that you really should be setting the DateTime property. Your Edit() POST method has
Delivery delivery = new Delivery()
{
DriverID = model.DriverID,
};
db.Deliverys.Add(delivery);
however an Edit() method suggests your editing and existing object, so it should be
// Get the data model based on the ID of the view model
Delivery delivery = db.Delivery.Find(model.ID);
// Map the view model properties to the data model
delivery.DriverID = model.DriverID;
// Mark as modified and save
db.Entry(order).State = EntityState.Modified;
db.SaveChanges();

Here is my model :
public class NomsPRItem
{
public long RequestID { get; set; }
public long PartID { get; set; }
public string PartNumber { get; set; }
public string PartDesc { get; set; }
public string UnitName { get; set; }
public double PartQuantity { get; set; }
public string CurrName { get; set; }
public double PiecePrice { get; set; }
public DateTime DeliveryDate { get; set; }
public string ProposeSuppliers { get; set; }
public string Comments { get; set; }

public string AccountType { get; set; }
public string InboxLearUID { get; set; }

public double TotalAmount { get; set; }
public double Amount { get; set; }
public string ItemId { get; set; }
public string FullName { get; set; }
}
}
And my connection
public static List<NomsPRItem> LoadPRItems(DateTime from, DateTime to)
{
string sSrcipt = m_sReport + "and p.[RequestDate] between '" + from.ToString("yyyy-MM-dd HH:mm:ss") + "' and '" + to.ToString("yyyy-MM-dd HH:mm:ss") + "'";
List<NomsPRItem> results = new List<NomsPRItem>();
using (SqlConnection con = new SqlConnection(m_sConnectionString))
{
con.Open();
using (SqlCommand command = new SqlCommand(sSrcipt, con))
{
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
results.Add( new NomsPRItem()
{
RequestID = reader.GetInt32(0)
,PartID = reader.GetInt32(15)
,PartDesc = reader.GetString(1)
,PartNumber = reader.GetString(7)
,SupplierID = reader.GetString(16)
,AccountType = reader.GetString(3)
,CurrName = reader.GetString(4)
,PartQuantity = (double)reader.GetDecimal(5)
,PiecePrice = (double)reader.GetDecimal(6)
,Amount = (double)reader.GetDecimal(5) * (double)reader.GetDecimal(6)
});
}
}
}
return results;
}
}
I am using angularjs in this, so I am converting this data to JSON ..
Here is my controller :
public JsonResult GetList()
{
DateTime today = DateTime.Now;
List<NomsPRItem> model = CheckerConnection.LoadPRItems(new DateTime(today.Year, today.Month, 1, 0, 0, 0), today);
return Json(model, JsonRequestBehavior.AllowGet);
}
public JsonResult GetReportList(string from, string to)
{
DateTime fromd = DateTime.Now;
DateTime tod = DateTime.Now;
if (from != "undefined")
fromd = Convert.ToDateTime(from);
if (to != "undefined")
tod = Convert.ToDateTime(to);
fromd = new DateTime(fromd.Year, fromd.Month, fromd.Day, 0, 0, 0);
tod = new DateTime(tod.Year, tod.Month, tod.Day, 23, 59, 59);
return Json(CheckerConnection.LoadPRItems(fromd, tod), JsonRequestBehavior.AllowGet);
}
I hope someone can help me on this mistake !
Your requestID is long and you are converting it to Int32.Change it to Int64 like this.
RequestID = reader.GetInt64(0)
,PartID = reader.GetInt64(15)

Entity Framework 4 CTP 5 Self Referencing Many-to-Many

I have the following scenario in my database. It is a record of Studies and those studies have other studies as prerequisites. In my DB design, it looks like this:
And my code looks something like this:
public class Study
{
public int ID { get; set; }
public string Topic { get; set; }
public byte TypeID { get; set; }
public virtual StudyType Type { get; set; }
public bool Deprecated { get; set; }
public virtual ICollection<Study> Prerequisites { get; set; }
}
public class StudyType
{
public byte ID { get; set; }
public string Name { get; set; }
public virtual ICollection<Study> Studies { get; set; }
}
public class MyContext : DbContext
{
public DbSet<Study> Studies { get; set; }
public DbSet<StudyType> StudyTypes { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Study>()
.HasMany(p=>p.Prerequisites)
.WithMany().Map(ps =>
{
ps.ToTable("Prerequisites");
ps.MapLeftKey(x=>x.ID,"StudyID");
ps.MapRightKey(y=>y.ID,"PrerequisiteID");
});
}
I'm not super good at the EF syntax, but from what I've found Googling, that seems like it should work. Instead, I get Sequence contains more than one matching element.
I found this, but since the entity is referencing itself, I can't exactly rename the key field in only one of the tables: http://social.msdn.microsoft.com/Forums/eu/adonetefx/thread/745a2c4f-cb66-41ad-9524-15aa198c40c7
Anybody help me through this?

Here is the full stack trace of the exception:
It executes on a line of LINQ: var x = from s in db.Studies select s;

This is what I have in an EntityTypeConfiguration<> implementation for a similar situation in CTP5.
HasMany(g => g.SubGroups)
.WithMany(g => g.ParentGroups)
.Map(m => m.ToTable("Groups_SubGroups"));
Not sure exactly how that translates to configuring the DbContext directly, but I imagine it should be close.
If memory serves, LeftKey() RightKey() syntax wasn't quite there in CTP5, so you just have to use the default column names that it creates or is expecting. In my case, it is GroupId and GroupId1. That follows the pattern <class>Id and <class>Id1, not <field> and <field>1 by the way.
The error that you're getting does seem familiar and I don't remember that the solution was obvious in any way. But, I did set this all up a while ago so the memories of how I arrived at something that works is a bit swiss cheesed. Hope it helps some.
