Passing the “owner”-identity to the create-view for a related model
0
I have this viewmodel for Employees:
public class EmployeeViewModel
{
public int Id { get; set; }
// some more properties
public List<EmployeeReservationViewModel> Reservations { get; set; }
}
... and this one for EmployeeReservations:
public class EmployeeReservationViewModel
{
public int Id { get; set; }
public int EmployeeId { get; set; }
// some more properties
public EmployeeViewModel Employee { get; set; }
}
In the Employees Details-view, I have a link for adding a new EmployeeReservation, like this:
<a asp-controller="EmployeeReservations"
asp-action="Create">Add reservation</a>
How should I pass the EmployeeId to the EmployeeReservations/Create-View?
At the moment I'm using a session-variable, like this, in the Employees's Details-method in the controller:
HttpContext.Session.SetInt32("EmployeeId", employee.Id);
... and then retreiving it in the Create POST-method in the EmployeeReservations-controller:
employeeReservation.EmployeeId = HttpContext.Session.GetInt32("EmployeeId").Value;
db.Add(employeeReservation);
await db.SaveChangesAsync();
I have a feeling my method is not optimal. What if the session times out? Is there another, more fail-safe method of doing it?

You can use asp-route-id
In view
<a asp-controller="EmployeeReservations"
asp-action="Create" asp-route-id="10">Add reservation</a>
In Controller add id as parameter fore create action
Public IActionResult Create(string id){
}

I have to add this in theCreate-view to make that work:<input type="hidden" name="EmployeeId" value="@ViewContext.RouteData.Values["id"]" />. Am I right? Because I tested it, and it works. But it seems a bit "hacky" to have to add manual hidden inputs in the view.

You can use it like this but good practice is passing the employee id in a model to view from create controller

It worked when I added:EmployeeReservationViewModel vm = new EmployeeReservationViewModel { EmployeeId = id }; return View(vm);in the create GET method and<input type="hidden" asp-for="EmployeeId" />in the create-view. :)
