I'm having a lot of trouble trying to create a partial view on my home controller from a .edmx model.
I cannot change the properties of this model because it is a part of another system that I am building this Website around.
I have spent a very long time trying to work this out and have came here to hopefully get some help and advice.
Aim: Render a partial _Patient.cshtml view on the Homepage using models in an .edmx model. I would like for you to show me where I have gone wrong as it does not work.
What is the problem?
I get multiple errors such as:
model: : EntityType model has no key defined. Define the key for this entity type.
The model item passed into the dictionary is of type 'Models', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`
using the generic type 'system.collections.generic.ienumerable requires 1 type arguments MVC
Currently I'm getting this error but I get the feeling that it's at the front of a long list of them.
The model item passed into the dictionary is of type 'FaceToFaceWebsite.Models.PatientListViewModel', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[FaceToFaceWebsite.Models.PatientListViewModel]'.
Below is the .edmx (as I cannot post images yet..
User (edmx) -Properties- UserID CodeName UseBriefInstructions Device_DeviceID -Navigation Properties- Device RegimeItems
Device -Properties- DeviceID Name -Navigation Properties- Users
Session -Properties- SessionID ActiveUserID ActiveDeviceID StartedAt ReachedFinish -Navigation Properties- SessionExcercises
(the Edmx is alot bigger than shown however these are the models that i currently need to use. however session and user are infact linked through another model)

I've posted everything i see as relevant, if you need anymore information please let me know. I apologise if the solution is simple, im new to MVC and this problem has gone on for quite some time.
---------UPDATE 2.0------------- Views/home/index.cshtml
@model FaceToFaceWebsite.Models.PatientListViewModel
@{

}

You are passing back the PartialView as a Result:
return PartialView("_Patient", new FaceToFaceWebsite.Models.PatientListViewModel());
Change this to return View(model); In your Index function. This will return your Home Page "Views/Home/Index.cshtml", and in this Index view you have:
@Html.Partial("_Patient", Model)
Which will Render the Partial View. But you are passing the wrong Model to your Index View: in Controller you are passing PatientListViewModelBut in you index you have: IEnumerable<FaceToFaceWebsite.Models.PatientHomeViewModel>.
So either you pass IEnumerable<FaceToFaceWebsite.Models.PatientHomeViewModel>,
like this:
public ActionResult Index(){
return PartialView(new FaceToFaceWebsite.Models.PatientListViewModel());
}
And then you can call Partial View like this:
@model IEnumerable<FaceToFaceWebsite.Models.PatientHomeViewModel>
@{
ViewBag.Title = "Home Page";
}
@Html.Partial("_Patient", Model)
What you should do.
Controller:
public ActionResult Index()
{
var viewModel = PatientListViewModel();
viewModel.PatientList = new List<Patients>();
viewModel.CustomerList = new List<Cusotmer>();
return View(viewModel);
}
Index.cshtml
@model PatientListViewModel
@* Considering your partial view is in Shared Foler*@
// Note Passing the Correct Model to Partial View
@Html.Partial("_Patient", Model.PatientsList)
// Another Example:
@Html.Partial("_Customer", Model.CustomerList)
Your _Patient.cshtml (partial View)
@model List<PatientsList>
@foreach(var item in Model){
item.Name
}
Your _Customer.cshtml (partial View) // Another Example
@model List<Custom>
@foreach(var item in Model){
item.Name
}
Your ViewModel:
public class PatientListViewModel{
public List<Patient> PatientsList {get;set;}
public List<Customer> CustomerList{get;set;}
}
public class Patient{
public string Name {get;set;
}
// Another Example
public Class Customer{
public string Name{get;set;
}
UPDATE
@model FaceToFaceWebsite.Models.PatientListViewModel
@{
ViewBag.Title = "Home Page";
}
// PatientListViewModel this is the Name of you class
// To Access your Model you always have to use Model. Not the Class Name
// PatientListViewModel is the Class name
// Model is the Object --> You passed from Controller.
// Use Model.PatientProfile
// Not PatientListViewModel.PatientProfile
@Html.Partial("_Patient", Model.PatientProfile)
