ASP.NET MVC multiple models in one view

Question

I have the following models Patient Class:

public class Patient
{
    public int PatientID { get; set; }

    public virtual Salutation salutation { get; set; }
    public int SalutationID { get; set; }
    public string Surname { get; set; }
    public string Firstname { get; set; }
    [Display(Name = "Date of Birth")]
    [DisplayFormat(DataFormatString="{0:d}", ApplyFormatInEditMode=true)]
    public DateTime DOB { get; set; }
    public string RegNo { get; set; }
    public DateTime RegDate { get; set; }
    public string Occupation { get; set; }
}

VatalSigns Class

public class VitalSign
{
    public int VitalSignID { get; set; }
    public string Sign { get; set; }
    [Display(Name = "Lower Limit")]
    public int? LowerHold { get; set; }
    [Display(Name = "Upper Limit")]
    public int? UpperHold { get; set; }
    [Display(Name = "Unit Of Measurment")]
    public string Units { get; set; }
}

PV class that stores VitalSigns for each patient

public class PVSign
{

    public long PVSignId { get; set; }
    [Display(Name = "Patient")]
    public int PatientID { get; set; }
    public VitalSign VitalSigns { get; set; }
    //public IList<VitalSign> VitalSigns { get; set; }
    public Patient patient { get; set; }

}

Now the problem I have is that I have not been able to get display on one from to enter the details. I want to select the Patient and the different Vitals signs will appear and I will save the ones I need to the PVSign table.

I have tired all sorts of samples from the web. You can see from the code below, this is the index stub:

public ActionResult Index()
{
    var pVSigns = db.PVSigns.Include(p => p.patient).Include(p => p.PVSignId).Include(p => p.VitalSigns);
    //var pVSigns = from o in db.Patients join o2 in db.PVSigns
    //List<object> myModel = new List<object>();
    //myModel.Add(db.Patients.ToList());
    //myModel.Add(db.VitalSigns.ToList());

    //return View(myModel);
    return View(pVSigns.ToList());
}

How to I solve this issue. I am new to MVC, if it was Webforms, I would have been through with this project.

Thank you.

why not encapsulate all your models into one and then pass it? — jamiedanq

There is no single answer(solution) to this(your) problem. It depends on how you want to design/build/achieve your solution. The simple, brute solution : Just have a view model as a wraper that has as his properties the classes(models) you made and work around that,

public class FullPatientDetailsViewModel
{
    public Patient { get; set;}
    public List<PVSign> PatientPvSigns { get; set;} // Patien PV Signs
}

Or use just a PatientViewModel and load his PVSigns async with Ajax. There is no simple best solution, it all depends about what do you want to achieve as a bigger picture.

I've answered a similar question here. As Alexandru mentioned, the easiest and most straightforward way would be to wrap your models inside a ViewModel. You can read about other ways to implement this here.
