UmbracoVirtualNodeByIdRouteHandler - How to get the node by Guid (Custom Routing)

Extending Umbraco and using the API

Umbraco 7
Hi Guys,

Here is a bit of an issue I can trying to figure out.
1. I started using Umbraco Courier 3 and it works great.
2. I noticed when Courier uploads nodes/documents to the live environment the Id is different but it retains the same Guid. Fine! I expected this would be the case.
3. Because of this I have started referencing nodes by Guid rather than the Id since there wont be any confusion on local, staging, and live when referencing nodes.
4. This has been working fine for everything except this one issue.
Part of my application has custom routes within the application starting event.

E.g
```
RouteTable.Routes.MapUmbracoRoute(
                "JobSearch1",
                "find-a-job/search-jobs/{value1}",
                new
                {
                    controller = "Routing",
                    action = "JobList"
                },
                new UmbracoVirtualNodeByIdRouteHandler(1276));//job list page Id
```
Obviously as per my description above I no longer want to use Ids as the primary referencing. So this line of code becomes an issue.
```
new UmbracoVirtualNodeByIdRouteHandler(1276))
```
I couldn't find an equivilant that accepts a Guid. First of all if anyone knows an equivilant then please shout out.

I attempted to get around this by the following code
```
var umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);
int Id = umbracoHelper.TypedContent(guid).Id;

 RouteTable.Routes.MapUmbracoRoute(
                    "JobSearch1",
                    "find-a-job/search-jobs/{value1}",
                    new
                    {
                        controller = "Routing",
                        action = "JobList"
                    },
                    new UmbracoVirtualNodeByIdRouteHandler(Id));//job list page Id
```
The issue here is that in the starting event the context doesn't exist. I have using the EnforceUmbracoContext in the past with similar issues but in this case its not working and I am really not confidant this is the way to go. Its too much of an hack and I am guessing it's going to cause all sorts of problems at a later date.

Cant anyone point me in the right direction or give me some advise on this?

Thanks in advance.

Kind Regards

Hi,

So I have figured out a way around this. I am not sure if this the best way so I am keen to hear what other people are doing.

I use the same code for the custom route. The only difference is instead of using the Id of the page this will route to for the virtual node I simply use the Id of the homepage. This will always be the same between staging and live. Plus its not that important as long as its an Id that exists.
```
  RouteTable.Routes.MapUmbracoRoute(
                    "JobSearch1",
                    "find-a-job/search-jobs/{value1}",
                    new
                    {
                        controller = "Routing",
                        action = "JobList"
                    },
                    new UmbracoVirtualNodeByIdRouteHandler(1063));//Homepage Node Id
```
The next part of this hack is within the controller handing the return of the model. I simply created a new RenderModel based on the Guid I wanted to use then passed this back out instead of the virtual node as I was previously using.
```
public class RoutingController : Umbraco.Web.Mvc.RenderMvcController
{
    public ActionResult JobList(RenderModel model)
    {
        model = new RenderModel(BusinessManager.GetPublishedContentByGuid(Guid.Parse("a25dbd15-f4fb-4fc5-9b4d-23c40fd2e115")));
        return View("JobList", model);
    }
}
```
I hope this helps someone. If anyone knows of a better solution please let me know.

Kind Regards

Hi David,

You should never reference to a hardcoded node. Rather create your own virtual route handler.
```
public class FindJobPageRouteHandler : UmbracoVirtualNodeRouteHandler
{
    protected override IPublishedContent FindContent(RequestContext requestContext, UmbracoContext umbracoContext)
    {
        // change this to whatever you need, but make sure it is fast!
        var jobspage = umbracoContext.ContentCache.GetAtRoot().First().FirstChild<MyJobAreaDocType>(); 
        return jobspage ;
    }
}
```
Then replace your new UmbracoVirtualNodeByIdRouteHandler(1063) with new FindJobPageRouteHandler() when adding your route.

Like this you won't need the context to route to the correct page.

Hope this helps

Kind regards
Damiaan

PS: I won't mark your own reply as an accepted solution, if you want other people to jump in. Btw, it is only a workaround, not a solution. :-p
