如何將ASP.net的默認應用程序用戶附加到應用程序特定模型？

Question

這是這是創造這種模式

 [HttpPost] 
    [ValidateAntiForgeryToken] 
    public async Task<IActionResult> Create([Bind("ID,EmployerName")] Employer employer) 
    { 
     if (ModelState.IsValid) 
     { 

      //was hoping solution would be as easy as.. 
      //employer.User = HttpContext.User; 
      //but that is not working neither is anything else I find 

      _context.Add(employer); 
      await _context.SaveChangesAsync(); 
      return RedirectToAction("Index"); 
     } 
     return View(employer); 
    } 

當僱主模式沒有創建ApplicationUser的asp.net的默認設置被設定爲它在我的應用的模型

public class Employer 
    { 
     public int ID { get; set; } 
     public string EmployerName { get; set; } 
     public virtual ApplicationUser User { get; set; } 


    } 

。如何從當前會話中獲取用戶並在創建時將其設置爲模型實例。我對asp.net框架很陌生，所以原諒我缺乏理解。非常感謝您對此的閱讀。

假設這是ASP身份和用戶已登錄：

if (ModelState.IsValid) 
{ 
    string currentUserId = User.Identity.GetUserId(); 
    employer.User = _context.Users.FirstOrDefault(u => u.Id == currentUserId); 
    _context.Add(employer); 
    await _context.SaveChangesAsync(); 
    return RedirectToAction("Index"); 
} 

另一種選擇是存儲在會話的用戶。
