Hi Enrico,

The easiest way is to use UmbracoHelper like that:

var id = Umbraco.GetIdForUdi(udi);

Thanks,

Alex

this is always empty.

I tried also to implement IPublishedContentWithKey, but the key is always empty.

I checked also the file Umbraco.config in the folder App_Data and the key are ok for every content.

This all the code from my controller

public class MenuController : UmbracoApiController
    {

        [HttpGet]
        public HttpResponseMessage GetNavigation()
        {
            var linkItems = new List<LinkItem>();
            var homepage = Umbraco.ContentAtRoot().First();


            linkItems.Add(new LinkItem {Id = homepage.Id, Name = homepage.Name, ParentId = 0, Url = homepage.Url});

            foreach (var item in homepage.Children.Where("Visible"))
            {
                linkItems.AddRange(GetChildLinks(item));
            }

            var response = Request.CreateResponse(HttpStatusCode.OK, linkItems, new AngularJsonMediaTypeFormatter());
            response.Headers.Add("Access-Control-Allow-Origin", "*");
            return response;
        }


        [HttpGet]
        public HttpResponseMessage GetNavigationTree()
        {
            var menuItems = new List<MenuItem>();
            var homepage = Umbraco.ContentAtRoot().First();

            // menuItems.Add(new MenuItem { Id = homepage.Id, Name = homepage.Name, ParentId = 0, Url = homepage.Url });

            foreach (var item in homepage.Children.Where("Visible"))
            {
                menuItems.AddRange(GetTreeLinks(item));
            }

            var response = Request.CreateResponse(HttpStatusCode.OK, menuItems, new AngularJsonMediaTypeFormatter());
            response.Headers.Add("Access-Control-Allow-Origin", "*");
            return response;
        }

        private List<LinkItem> GetChildLinks(dynamic item)
        {
            var newItems = new List<LinkItem>();

            newItems.Add(new LinkItem {
                        Id = item.Id,
                        Name = item.Name,
                        ParentId = item.ParentId,
                        Url = item.Url

            });


            foreach (var sub in item.Children.Where("Visible"))
            {
                newItems.AddRange(GetChildLinks(sub));
            }

            return newItems;
        }

        private List<MenuItem> GetTreeLinks(dynamic item)
        {
            var newItems = new List<MenuItem>();
            var tempItems = new List<MenuItem>();

            foreach (var sub in item.Children.Where("Visible"))
            {
                tempItems.AddRange(GetTreeLinks(sub));
            }

            newItems.Add(new MenuItem
            {
                name = item.Name,
                link = tempItems.Any() ? "#" : item.id.ToString(),
                url = item.Url,
                subtree = tempItems.Any() ? tempItems : null

            });

            return newItems;
        }



    }

Enrico, did you try this method - https://github.com/Shazwazza/Articulate/blob/master/src/Articulate/Models/PublishedContentExtensions.cs#L52?

public static IPublishedContentWithKey GetContentWithKey(IPublishedContent model)
        {
            var withKey = model as IPublishedContentWithKey;
            if (withKey != null) return withKey;

            var wrapped = model as PublishedContentWrapped;
            if (wrapped != null)
            {
                return GetContentWithKey(wrapped.Unwrap());
            }
            return null;
        }

        public static Guid GetContentKey(this IMasterModel model)
        {
            var withKey = GetContentWithKey(model);
            if (withKey != null) return withKey.Key;
            return Guid.Empty;
        }

I tried also this approach.

I also tried to restore the obselete editors adding the key

<showDeprecatedPropertyEditors>true</showDeprecatedPropertyEditors>

in the file 'umbracoSettings.config' under the folder 'Config'

Now it's two days that I stuck. I think I will give up and downgrade Umbraco to a previous version where the old editors were in use.

The reason why i wanted to to do this is because I am working with the Umbraco Rest API, that only accepts ids to retrieve the content and does not accept routes or udi.

Enrico, try to disable PropertyValueConverters.

The Property value converters are controlled by an umbracoSetting.config setting: in section settings/content, setting EnablePropertyValueConverters set to false.

And you will be able to use old school ids in your properties.

will not help you

Thanks for your kind help.

But also this setting doesn't work.

I will try tomorrow with an older version of Umbraco. Hopefully the code I already wrote, will work.

Hi Enrico

Yes, Examine is the fastest way to query data from Examine index, it's not the same as cache little bit. But it's the fastest way to query data.

Did you read this article: https://our.umbraco.org/documentation/reference/Common-Pitfalls/

Thanks,

Alex

Here is a JavaScript function that I wrote to match and replace udi. The input is the html string to parse and the sitelinks is a list of the Umbraco pages.

    function filterByUdi() {
    return function(input, siteLinks) {

        if (input) {

            var regex2 = /href=\"\/{localLink:umb:\/\/document([^\"]*)"/g;
            var links = input.match(regex2);

            if (links && siteLinks) {

                var output = input.replace(/data-udi=\"([^\"]*)\"/g, "");

                for (var j = 0; j < siteLinks.length; j++) {
                    for (var k = 0; k < links.length; k++) {
                        if (links[k].includes(siteLinks[j].NodeUdi)) {
                            if (siteLinks[j].Url === "/") {
                                output = output.replace(links[k], 'href=\"#!home\"');
                            } else {
                            output = output.replace(links[k], 'href=\"#!' + siteLinks[j].Url + '\"');
                            }
                        }
                    }
                }

                return output;
            }
        }

        return input;
    };
}

I hope it could be helpful

Thanks @Enrico for the solution.

After the Umbraco 8 Code clean up the accessing methods got changed compared to Umbraco 7

So, I have updated the code for Get UID from ID in Umbraco 8 as follows

    using Umbraco.Core;

    private GuidUdi GetUdi(int id)
    {
        var node = Services.ContentService.GetById(id);
        if (node != null)
        {
            return node.GetUdi();
        }
        return null;
    }

is working on a reply...
