View engine does not render the view when I pass a model from the controller

Question

I am developing an MVC3 application using C# and Razor. I have a problem when I need to display one the Play View.

The Play action method is used to retrieve a path of a FLV (Flash) file to be then passed to the Play View to reproduce the file. When I use return View("Play") the application renders the View correctly. However I need to pass the path variable to the View as shown in the code. When I do it I receive the following message:

The view 'Play' or its master was not found or no view engine supports the searched locations

Here is the Action Method:

public ActionResult Play(int topicId)
{
var ltopicDownloadLink = _webinarService.FindTopicDownloadLink(topicId);

if (ltopicDownloadLink != null)
{
    var path = Server.MapPath("~/App_Data/WebinarRecordings/" + ltopicDownloadLink);
    var file = new FileInfo(path);
    if (file.Exists)
    {
        return View("Play", path);
    }
}

return RedirectToAction("Index");
}

Here is the Play View:

@model System.String

<div id='player'>This div will be replaced by the JW Player.</div>

<script type='text/javascript' src='/FLV Player/jwplayer.js'></script>

<script type='text/javascript'>

   var filepath = @Html.Raw(Json.Encode(Model));

   jwplayer('player').setup({
   'flashplayer':'/FLV Player/player.swf',
   'width': '400',
   'height': '300',
   'file': filepath
   });
</script>

My only hint is that I make some mistake in using the model in the javascript. May you please help me?

Thanks

Answer 1

You are invoking a wrong overload. Here's the correct overload:

return View("Play", (object)path);

or you could also declare the path variable as object:

object path = Server.MapPath("~/App_Data/WebinarRecordings/" + ltopicDownloadLink);

and then

return View("Play", path);

will also work:
