Need help with MVC 4 Entity Framework

I am using a Model Wrapper to include three models into one view as below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace RescueFormsAdministration.Models
{
    public class CreateAccountViewModel
    {
        public Account AccountModel { get; set; }
        public Data DataModel { get; set; }
        public Phone PhoneModel { get; set; }
    }
}

I modified the Create ActionResult in the AccountsController to use the CreateAccountViewModel instead of Account. This works fine after I also modified the -CreateOrEdit.cshtml partial class to use the CreateAccountViewModel as well
        [HttpPost]
        public ActionResult Create(CreateAccountViewModel accountViewModel)
        {
            if (ModelState.IsValid)
            {
                context.Accounts.Add(accountViewModel.AccountModel);
                context.SaveChanges();
                return RedirectToAction("Index");  
            }

            return View(accountViewModel);
        }


 I am having trouble modifying the non-HttpPost Edit Edit ActionResult

        public ActionResult Edit(int id)
        {
            Account account = context.Accounts.Single(x => x.AccountsID == id);
            return View(account);
        }

The problem is when I change Account account to CreateAccountViewModel accountViewModel  I get a problem with this line:

CreateAccountViewModel accountViewModel = context.Accounts.Single(x => x.AccountsID == id);

I get the error:
“Cannot implicitly convert type 'RescueFormsAdministration.Models.Account' to 'RescueFormsAdministration.Models.CreateAccountViewModel'       

'RescueFormsAdministration.Models.Account' is one of the three Models that I have placed into the CreateAccountViewModel wrapper and 'RescueFormsAdministration.Models.CreateAccountViewModel' is of course the name of the Model Wrapper itself.

Can anyone please help me?

context.Accounts.Single return an Account. You're trying to assign the Account to a CreateAccountViewModel. They aren't the same thing. That's exactly what the error message is telling you. You need to assign the results of context.Accounts.Single to the AccountModel inside CreateAccountViewModel.

CreateAccountViewModel accountViewModel = new CreateAccountViewModel();
accountViewModel.AccountModel = context.Accounts.Single (...)

OK, I am slowly getting there, this fixed my problem with...

public ActionResult Edit(int id)

now I have a prolem after the Edit with that I belive is related since I get the same error message

        [HttpPost]
        public ActionResult Edit(CreateAccountViewModel accountViewModel)

How can I award you the 500 points and create another question but get it to your attention since you were able to fix the first problem?
