ASP.NET MVC 5空的ApplicationUser

Question

I have a table with [QuestionID] [Description] [User_id].

public int QuestionID { get; set; }
public string Description { get; set; }
public ApplicationUser user { get; set; }

The question is stored in the database when a user sends a question using a form and all the fields are saved correctly.

I send a list from my QuestionController with all the questions to my view:

return View(db.Questions.ToList());

In my view I use that list:

@foreach (var item in Model)
{
    <tr>
        <td class="td-title">
            @Html.DisplayFor(modelItem => item.QuestionID)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.user.id)
        </td>
   </tr>
...

Everything works except the item.user.id which shows no value (it is filled in the database). How come this is empty? And what can I do to show the user information?

Edit:

I use code-first and this is how I fill in the database:

public ActionResult Create([Bind(Include = "QuestionID,Description")] Question question)
{
    if (ModelState.IsValid)
    {
        question.user = UserManager.FindById(User.Identity.GetUserId());

        db.Questions.Add(question);
        db.SaveChanges();
        return RedirectToAction("Index");
    }
    return View(question);
}

Example of database result after form:

[QuestionID]  [Description]  [user_Id]
      1          blalbla..    397d27d...

Answer 1

Did you try "public virtual ApplicationUser user { get; set; }" ?

I think you have to make it virtual to access ApplicationUser properties or change the code in your view to "@Html.DisplayFor(modelItem => item.user)"
