How to Edit and Save ViewModels data back to database

Question

I have a ViewModel which is joined by three Entities to get data from all entities into one view form. Although i succeeded to implement the same. But i have no idea how to Edit and Save data back to the database. My model classes are joined by one to one relationship.

My Models are:

public class Doctor
{
    public int DoctorId { get; set; }
    public string Name { get; set; }
    public string Speciality { get; set; }

    public virtual DoctorAddress DoctorAddress { get; set; }
    public virtual DoctorCharge DoctorCharge { get; set; }
    public virtual DoctorAvailablity DoctorAvailablity { get; set; }

}

public class DoctorAddress
{
    public string Address { get; set; }
    public string City { get; set; }
    public int DoctorId { get; set; }

    public virtual Doctor Doctor { get; set; }
}

public class DoctorCharge
{
    public decimal OPDCharge { get; set; }
    public decimal IPDCharge { get; set; }
    public int DoctorId { get; set; }

    public virtual Doctor Doctor { get; set; }
}

My ViewModel is:

public class DoctorViewModel
    {
        public Doctor Doctor { get; set; }
        public DoctorAddress DoctorAddress { get; set; }
        public DoctorCharge DoctorCharge { get; set; }

    }

My Controller is:

public ActionResult Index()
    {
        var model = from t1 in db.Doctors
                    join d in db.DoctorAddress on t1.DoctorId equals  d.DoctorId into listi
                    join dc in db.DoctorCharges on t1.DoctorId equals dc.DoctorId into listj

                    from d in listi.DefaultIfEmpty()
                    from dc in listj.DefaultIfEmpty()

                    select new DoctorDetailsViewModel.DoctorViewModel { Doctor = t1, DoctorAddress = d, DoctorCharge = dc };

        return View(model.ToList());

    }

My View is:

@model XXX.DoctorDetailsViewModel.DoctorViewModel

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<fieldset>
    <legend>Doctor</legend>

    <div class="editor-label">
       Name
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Doctor.Name)
    </div>

    <div class="editor-label">
        OPD Charge
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.DoctorCharge.OPDCharge)
    </div>

<div class="editor-label">
        Address
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.DoctorAddress.Address)
    </div> <p>
        <input type="submit" value="Create" />
    </p>
</fieldset>}

My Controller Class is:

public ActionResult Create()
    {
        return View();
    }

    //
    // POST: /Doctor/Create

    [HttpPost]
    public ActionResult Create(Doctor doctor)
    {
        if (ModelState.IsValid)
        {
            db.Doctors.Add(doctor);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        return View(doctor);
    }

Please help me how do i do. Thanks in advance.

Here, for creating:

[HttpPost]
public ActionResult Create(DoctorViewModel model)
{
    if (ModelState.IsValid)
    {
        model.Doctor.DoctorAddress = model.DoctorAddress;
        model.Doctor.DoctorCharge = model.DoctorCharge;
        db.Doctors.Add(doctor);
        db.SaveChanges();
        return RedirectToAction("Index");
    }

    return View(doctor);
}
