Question

我有一个“恢复”视图，它调用了RenderAction，因此我可以在简历中添加注释。代码：

    @{Html.RenderAction("Add", "ResumeComment", new { resumeId = @Model.Id });}

所以上面的代码在我的ResumeComment控制器中调用Add动作并传递resumeId。如果我在Add（GET）方法中查看我的ControllerContext.ParentActionViewContext.RouteData，我会看到4个值：

PL <- which is resume category
954 <- resume id
Resume <- Controller
Edit <- Action, because I am adding comments on the Edit page in the resume.

The problem that I have is that I am loosing resume category (PL) and resume id(954) when I post (add a comment). Here is my ResumeComment form:

    @using (Html.BeginForm("Add", "ResumeComment"))
    {
    ...
    <input type="submit" value="Add Comment" />   

    ..}

So this form will call Add (Post) method in the ResumeComment controller when sumitted. Here is my add method:


    [HttpPost, ActionName("Add")]  
    public ActionResult Add(ResumeComment resumeComment)
    {
    .....
    }

I am not able to access ControllerContext.ParentActionViewContext.RouteData at all, it is null. I am however able to access ControllerContext.RouteData but when I look at the values I only see "ResumeComment" and "Add" in there and that is it. How can I preserve the resume category and resume id?

Answer 1

如果您想将表单中的某些值发布到ResumeComment.Add，则需要将它们放入隐藏的输入中。 RouteData在请求之间不存在任何神奇的方式。

Answer 2

您可以使用TempData - 类似会话，但一旦您从中读取数据就会被删除。它是在两个连续请求之间存储临时数据的好方法。

RouteData在由RenderAction调用的控制器中丢失
