How do I get my view to show my database table - asp.net-mvc

Question

i'm new to ASP.net. I am trying to figure out how to get my Edit/Display pages working properly for a multiselect listbox.
My create works fine, and saves to my database, but I cannot figure out how to return to the edit page, and still see the values selected.
Hopes this makes sense.
Here is the code that I have for the create method. The record saves fine in both tables, but I am having trouble getting the values from my Options table.
I want to try to make the Edit view look like the Create View
Controller
[HttpPost]
public IActionResult Create(MusicViewModel model)
{
if(ModelState.IsValid)
{
var album = new Music();
album.Album = model.Album;
album.Artist = model.Artist;
album.Label = model.Label;
album.Review = model.Review;
album.ReleaseDate = model.ReleaseDate;
foreach(Types type in model.Options)
{var opt = new Options();
opt.Music = album;
opt.Types = type;
_musicData.AddOptions(opt);
}
_musicData.Add(album);
_musicData.Commit();
return RedirectToAction("Details", new { id = album.MusicID });
}
return View();
}
Music.cs
public enum Types
{
Spotify,
Groove,
CD,
Vinyl,
Pandora
}
public class Music
{
public int MusicID { get; set; }
[Required]
[MaxLength(50),MinLength(5)]
public string Artist { get; set; }
[Required, MinLength(5)]
public string Album { get; set; }
public int Rating { get; set; }
public Label Label { get; set; }
[DataType(DataType.Date)]
[Display(Name ="Release Date")]
public DateTime ReleaseDate { get; set; }
public string Review { get; set; }
public List<Options> Options { get; set; }
}
public class Options
{
public int OptionsID { get; set; }
public Types Types { get; set; }
public int MusicID { get; set; }
public Music Music { get; set; }
}
public class MusicDbContext:DbContext
{
public DbSet<Music> Albums { get; set; }
public DbSet<Options> Options { get; set; }
}
View
#model Music
....

Answer 1

I figured it out, probably not the most efficient way, but at least the code works
[HttpPost]
public IActionResult Edit(int id,MusicViewModel model)
{
var album = _musicData.GetM(id);
if (album != null && ModelState.IsValid)
{
album.Album = model.Album;
album.Artist = model.Artist;
album.Label = model.Label;
album.Review = model.Review;
album.ReleaseDate = model.ReleaseDate;
_musicData.RemoveOptions(id);
foreach (Types type in model.Options)
{
var opt = new Options();
opt.MusicID = id;
opt.Types = type;
_musicData.AddOptions(opt);
}
_musicData.Commit();
return RedirectToAction("Details",id);
}
return View(album);
}
