asp.net-mvc – RenderAction应该与表单一起使用吗？

在我看来(/步骤/细节)我有：

<!-- List comments -->
<% Html.RenderAction("List","Comments",new { id = Model.Step.Id }); %>

<!-- Create new comment -->
<% Html.RenderAction("Create",new { id = Model.Step.Id }); %>

在我的评论控制器中,我有我的POST方法：

// POST: /Comments/Create
    [HttpPost]
    public ActionResult Create([Bind(Exclude = "Id,Timestamp,ByUserId,ForUserId")]Comment commentToCreate)
    {
        if (ModelState.IsValid)
        {
            //Insert functionality here

            return RedirectToAction("Details","Steps",new { id = commentToCreate.StepId });

        }

    //If validation error
        else
        {

            //Store modelstate from tempdata
            TempData.Add("ModelState",ModelState);

            //Redirect to action (this is hardcoded for now)
            return RedirectToAction("Details",new { id = commentToCreate.StepId });
        }
    }

在评论控制器中也是我的GET方法：

//
    // GET: /Comments/Create

    public ActionResult Create(int id)
    {

        if (TempData.ContainsKey("ModelState"))
        {
            ModelStateDictionary externalModelState = (ModelStateDictionary)TempData["ModelState"];
            foreach (KeyValuePair<string,ModelState> valuePair in externalModelState)
            {
                ModelState.Add(valuePair.Key,valuePair.Value);
            }
        }
        return View(new Comment { StepId = id });
    }

这对我很有用,但我很感激这是一个好习惯的反馈,等等.

另外,我注意到MvcContrib有一个ModelStateToTempData装饰,看起来这样做,但是更清洁.我接下来要尝试一下.
