Question

My update method is not working in an ASP.NET MVC 3 application. I have used the following EF 4.1 code:

[HttpPost]
public ActionResult UpdateAccountDetails(Account account)
{
    if (ModelState.IsValid)
    {
        service.SaveAccount(account);
    }
}

and SaveAccount looks like this:

internal void SaveAccount(Account account) {         
    context.SaveChanges();
}

Answer 1

internal void SaveAccount(Account account) {

    // Load current account from DB
    var accountInDb = context.Accounts.Single(a => a.Id == account.Id);

    // Update the properties
    context.Entry(accountInDb).CurrentValues.SetValues(account);

    // Save the changes
    context.SaveChanges();
}

Alternative:

internal void SaveAccount(Account account) {

    context.Entry(account).State = EntityState.Modified;
    context.SaveChanges();
}
