Null after asp.net post? Editting models

Question

I'm new to asp.net, but I'm having a ridiculous amount of trouble creating a simple Edit method. I've googled alot, but it was of no help.Though I've seen this issue accure no answers were relevent to my case.

I've made the create methods, but during edit method, after retrieving data from the form, all of the attributes seam to be either empty or 0.

I've spent two days on this and have no clue what to do. Please please advise.

These are the two methods of the controller are

 public IActionResult Edit(int? id)
        {
            if (id == null)
            {
                return HttpNotFound();
            }

            Question question = _context.questions.Single(m => m.id == id);
            if (question == null)
            {
                return HttpNotFound();
            }
            return View(question);
        }


        [HttpPost]
        public  IActionResult Edit( Question question)
        {
            if(question.id == 0)
                return HttpNotFound();

            //      _context.questions.Attach(question);
            //         _context.Entry(question).State = EntityState.Modified;
            //         _context.SaveChangesAsync();

            return RedirectToAction("Index");

        }

The view's form

        Question
        
        
        
            
        
        
            
            
                
                
            
        
        
            
            
                
                
            
        
        
            
            
                
                
            
        
        
            
                
            
        
    



    Back to List


@section Scripts {
    
    
    
}

namespace Daycare.Models { public class Question {

    public Question() {

    }

    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int id { get; set; }
    public string title { get;set;}

    public string question { get; set; }

    public string answer { get; set; }
    public DateTime date { get; set; }
}

}

The model is just a very simple thing with an Int Id and some string attributes.

Please tell me, why is this error accuring?

It seemed to be a bug. Creating a viewmodel and using it aroung the model helped.
