Question

使用Windows身份验证创建了一个应用。我需要您的建议，关于如何显示谁是元素的创建者（或被其修改）以及何时（或何时更改）的信息？

我的模特是

  Public class Movie

    {

    public int Id {get;set;}

    public string Text{get;set;}

    public datetime Created{get;set;}

    public string CreatedBy {get;set;}

    public datetime Modified{get;set;}

    public string ModifiedBy {get;set;}           
    }

控制器是

public ActionResult Create()
        {
            return View();
        }

        // POST: Movies/Create
        // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
        // more details see https://go.microsoft.com/fwlink/?LinkId=317598.
        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create([Bind(Include = "Id,Text,Created,CreatedBy,Modified,ModifiedBy")] Movie movie)
        {
            if (ModelState.IsValid)
            {
                db.Movies.Add(movie);

                  db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(movie);
        }

Answer 1

重写您的Create操作，如下所示：

public ActionResult Create()
    {
        return View();
    }

    // POST: Movies/Create
    // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
    // more details see https://go.microsoft.com/fwlink/?LinkId=317598.
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "Id,Text")] Movie movie)
    {
        movie.CreatedBy = HttpContext.Current.User;
        movie.Created = DateTime.Now;
        if (ModelState.IsValid)
        {
            db.Movies.Add(movie);

              db.SaveChanges();
            return RedirectToAction("Index");
        }

        return View(movie);
    }

对于“编辑”操作，请执行与对“创建”操作相同的操作。希望有帮助！
