MVC ViewModel display - asp.net-mvc

Question

I am frustrated. I have a series of tables where I am trying to display fields from one model into another model's view. This is my table structure -
I am attempting to display Device, Status and Location fields in DeviceLog's detail view. I have created my own device model.
public class DeviceLogIndexData
{
public IEnumerable<DeviceLog> DeviceLogs { get; set; }
public IEnumerable<DeviceStatu> DeviceStatus { get; set; }
public IEnumerable<DeviceLocation> DeviceLocations { get; set; }
public IEnumerable<Location> Locations { get; set; }
public IEnumerable<Status> Status { get; set; }
public IEnumerable<Device> Devices { get; set; }
}
and have made several ways to use this. My latest attempt was -
var devicelog = new DeviceLogIndexData();
devicelog.DeviceLogs = db.DeviceLogs
.Include(d => d.Device)
.Include(d => d.Device.DeviceStatus.Select(s => s.Status))
.Include(d => d.Device.DeviceLocations.Select(x => x.Location))
.OrderBy(d => d.DeviceLogID);
devicelog = devicelog.DeviceLogs.Where(d => d.DeviceLogID == id.Value);
Now I am just totally frustrated and confused on how to use my ViewModel.

Answer 1

You want to project into your view model
var devicelog = db.DeviceLogs
.Include(d => d.Device)
.Include(d => d.Device.DeviceStatus.Select(s => s.Status))
.Include(d => d.Device.DeviceLocations.Select(x => x.Location))
.Where(d => d.DeviceLogID == id.Value)
.Select(d => new DeviceLogIndexData { Name = d.Device.Name, ... }).ToList();
This is all pseudo code. so you may need to play around with it a little.
Where your view model class looks something like this
public class DeviceLogIndexData {
public string Name {get;set;}
public string Status {get;set;}
public string Location {get;set;}
}
Then return an IEnumerable<DeviceLogIndexData> to your view.
