Kentico 12 MVC - The resource cannot be found message on page preview

Petline developer asked on May 2, 2019 22:53

I work on Kentico 12 MVC, and wanted to know something basic regarding URL pattern for previewing content only pages. I able to see the home page, but once I added another new content-only page type , and trying to preview that page I get "The resource cannot be found." message.

Under the " Page types> General > URL pattern" I tried "/{%NodeAlias%}" and "/blog" but none is working and I keep getting the above message when I preview or when I use the "Page" tab.

can someone please help, I am sure I am missing something really simple.

Thanks!

Well in your controller you currently have:

public ActionResult Index()
{
        OurBlog page = OurBlogProvider.GetOurBlog("/blog", "en-us", "KenticoTest");            
        ...
}

Which isn't dynamic at all...

You could change it to something like:

public ActionResult Index(int nodeId, string nodeAliasPath)
{
        OurBlog page = OurBlogProvider.GetOurBlog(nodeId,
            LocalizationContext.CurrentCulture.CultureCode,
            SiteContext.CurrentSiteName);
            // extend this with more properties like columns, only published, etc.

        ...
}

This will try to retrieve the pages based on the NodeID.

How MVC works is that you have registered Routes...

You have to make sure that the URL pattern you enter has a valid route that points to a controller that knows how to handle that url.

So first check the RouteConfig.cs probably in your App_start folder.

Say you have a news page. You could setup a route like (note that i simplified it):

        route = routes.MapRoute(
          name: "news",
          url: "news/{nodeId}/{nodeName}",
          defaults: new { controller = "News", action = "Detail", nodeName = UrlParameter.Optional }
          );

In the News Controller your Detailed action method can retrieve the page based on type (news) and nodeID which is in the URL.

    public ActionResult Detail(int nodeId, string nodeName)
    {
        /// ... some logic retrieving the model based on NodeID
        return View("NewsDetail", model);
    }

at this point you can setup your UrlPattern to be "news/{%NodeID%}/{%NodeAlias%}

Hi David,

Thanks so much for getting back to me, so under the RouteConfig.cs file I have this:

Code
            routes.MapRoute(
            name: "OurBlog",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "OurBlog", action = "Index", id = UrlParameter.Optional }
        );

And under the "OurBlogController" I have this:

Code
    public ActionResult Index()
    {
        OurBlog page = OurBlogProvider.GetOurBlog("/blog", "en-us", "KenticoTest");

        // Returns a 404 error when the retrieving is unsuccessful
        if (page == null)
        {
            return HttpNotFound();
        }

        // Initializes the page builder with the DocumentID of the page
        HttpContext.Kentico().PageBuilder().Initialize(page.DocumentID);

        return View(page);
    }

I did try what you suggested, but right now I have only one simple page, no sub pages. I still get the error. can you please advise what else I might be missing??

Thanks!

Yes but you don't use the ID parameter. So your query

OurBlogProvider.GetOurBlog("/blog", "en-us", "KenticoTest");

Will always return the same result. You should update it to use that property NodeID in it's dataretrieval.

sorry, not sure I understand, can you please specify what line I need to updated? Is the below line, is the only issue? OurBlogProvider.GetOurBlog("/blog", "en-us", "KenticoTest");

Or if you can provide an example based on what I am using.

thanks
