Hi, guys. I have a question related to ASP.Net MVC. I created a project with individual user accounts. And now I've created a model "Room".
<pre lang="c#">public class Room
        public int RoomId { get; set; }
        public string RoomName { get; set; }

        public string OwnerId { get;set }
        public virtual ApplicationUser Owner { get; set; }

And I added
public DBSet<Room> Rooms{get;set;}

And also I created a RoomController which has an ActionResult Create.
private ApplicationDbContext db = new ApplicationDbContext();
        // POST: Room/Create
        public ActionResult Create(Room room)
                // TODO: Add insert logic here

                return RedirectToAction("Index");
                return View();

I'm starting to learn ASP.Net just few weeks. And I've tried so many ways to solve this problem. Also

What I have tried:

Also I've tried to do some operations in HomeController. But it failed too. In my tables of Room there is no OwnerId. How can I connect this model with AspNetUsers?

You did not describe the problem.

I edited my text.Can you look one more time?

It is still impossible to tell where is the issue since we do not have the relevant code.
Have you tried debugging?
Member 14726247 14-Feb-20 7:56am
yes.but Create button doesn't work
Member 14726247 14-Feb-20 7:57am
so I don't know where is the problem

Only you can find out the issue. And you have a tool which is meant for that: debugging. Have you tried? Do you need help on how to debug an ASP.NET project?
Member 14726247 14-Feb-20 8:06am
i just tried debugging. and it says that "db.SaveChanges()" is not used. Because OwnerId and Owner have a null value

ASP.NET - Debugging[^] will introduce you to the concept of debugging.

There are a lot of other sources, though. Your favourite search engine will give you plenty of links about it.
Put a breakpoint on the line where you are assigning the owner; and follow the values of your variables from there.
