问题


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:

}

PLEASE NOTE: I didn't use ViewModels for Edit Order, only for Edit Delivery.


回答1:


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();
