asp.net-mvc – Umbraco Surface Controller或RenderMvcControll

嗨,我有’home’控制器和umbraco 7中的’sort’控制器.’home’控制器可以正常处理索引操作,因为它是从RenderMvcController重写的.首先,我很困惑我应该在哪种控制器中使用哪种控制器,即表面控制器或rendermvccontroller.我似乎无法访问下面的twitter动作,这是我需要的ajax.我是否需要将twitter动作放在表面控制器中,还是可以在umbraco中使用常规的mvc控制器？

public override ActionResult Index(RenderModel model)


       {
            var storedProcedure = new StoredProcedure()
            {
                ConnectionString = ConfigurationManager.ConnectionStrings["CentralDbContext"].ConnectionString
            };

            DataSet ds = storedProcedure.ExecuteProcedureToDataSet("GetHomePage");

            IMapSetup map = new MapHomePage();
            HomePage homepage = map.Setup<HomePage>(ds);


            homepage.Slideshow = CurrentPage.AncestorsOrSelf(1).First().Descendants("SlideshowItem").Take(5).AsMany<Slideshow>();

            this._weatherSettings.DefaultLocation = "warrington";
            homepage.Forecast = new Forecaster(this._weatherSettings,this._cacheHelper).GetWeather(this._weatherSettings.DefaultLocation);

            return CurrentTemplate(homepage);
        }
 public ActionResult TwitterSort(int? page)
    {
        int currentPageIndex = page.HasValue ? page.Value - 1 : 0;

        var storedProcedure = new StoredProcedure()
        {
            ConnectionString = ConfigurationManager.ConnectionStrings["CentralDbContext"].ConnectionString
        };

        DataSet ds = storedProcedure.ExecuteProcedureToDataSet("GetHomePage");

        IMapSetup map = new MapHomePage();
        HomePage homepage = map.Setup<HomePage>(ds);


        if (Request.IsAjaxRequest())
        {
            return PartialView("umbTweets",homepage.Twitter.ToPagedList(currentPageIndex,DefaultPageSize));
        }

        return PartialView(homepage.Twitter.ToPagedList(currentPageIndex,DefaultPageSize));
    }
