strange behavior with children node url when website is multilingual

Hi, I'm using v8.9.1 and I just noticed something very strange.

I have a multilingual site with the following Culture and Hostnames settings on the Home page. enter image description here

I'm listing Project children pages and the url is correct at first, e.g. http://localhost:52202/projects/ivy-tech-community-college/ but when I go to other languages, like http://localhost:52202/de and clicking on the same list, the url is not http://localhost:52202/de/projekt-archiv/ivy-tech-community-college/ but the same before, so http://localhost:52202/projects/ivy-tech-community-college/. Same problem with other languages.

If I save any content in the back-office, and refresh the page when I'm on the German site, the url is http://localhost:52202/de/projekt-archiv/ivy-tech-community-college/ on the page, and now switch to other languages, e.g. back to English, the url remains German.

The links are good when I visit the project children pages individually. enter image description here

I'm listing children like this:

var projects = Model.Root().Descendants().Where(x => x.IsDocumentType("projects")).FirstOrDefault(); 

@foreach(var project in projects.Where(x => x.IsVisible())){
    <a href="@project.Url">@project.Name</a>
}

Any idea or suggestion? Is it a bug maybe?

Additionally:

I read this article (https://24days.in/umbraco-cms/2020/multilingual-websites-in-umbraco-8/) and in section "Generating HrefLang Tags" I added the code to generate hreflang tags:

@foreach (var culture in Model.Cultures)
{
    string url = Model.Url(culture: culture.Key, mode: UrlMode.Absolute);

    if (!string.IsNullOrEmpty(url) && url != "#")
    {
        <link rel="alternate" href="@Model.Url(culture: culture.Key, mode: UrlMode.Absolute)" hreflang="@culture.Key" />
    }
}

The tags have generated on every pages except on these Project children pages (e.g. http://localhost:52202/projects/ivy-tech-community-college/) when it gave me an error: enter image description here

Hi.

I think Model.Cultures is a IReadOnlyDictionary<string, PublishedCultureInfo> So it would be culture.Value.Culture

like

@foreach (var culture in Model.Cultures)
{
    string url = Model.Url(culture: culture.Value.Culture, mode: UrlMode.Absolute);

    if (!string.IsNullOrEmpty(url) && url != "#")
    {
        <link rel="alternate" href="@Model.Url(culture: culture.Value.Culture, mode: UrlMode.Absolute)" hreflang="@culture.Value.Culture" />
    }
}

Thanks Bo, but it gives the same error. Actually this part of the code is not my main problem, but the this one:

var projects = Model.Root().Descendants().Where(x => x.IsDocumentType("projects")).FirstOrDefault(); 

@foreach(var project in projects.Where(x => x.IsVisible())){
    <a href="@project.Url">@project.Name</a>
}

I don't know why the url is the same when I change language.

You will always get the url of your main language. So you need to specify the culture like project.Url(culture: "fr-FR") but if you are using FirstOrDefault() you only get returned one project or null.

If you need the current culture then you can use Model.GetCultureFromDomains(), but what i think you need is this:

@foreach (var project in Model.Root().DescendantsOfType("projects").Where(x => x.IsVisible()))
{
    <a href="@project.Url(culture: "fr-FR")">@project.Name("fr-FR")</a>
}

or

@foreach (var project in Model.Root().DescendantsOfType("projects", "fr-FR").Where(x => x.IsVisible()))
{
    <a href="@project.Url(culture: "fr-FR")">@project.Name("fr-FR")</a>
}

@inherits Umbraco.Web.Mvc.UmbracoViewPage
@{
    Layout = null;

    var currentCulture = Model.GetCultureFromDomains();
    var projects = Model.Root().DescendantsOfType("projects", currentCulture).Where(x => x.IsVisible());
}

@foreach (var project in projects)
{
    <a href="@project.Url(culture: currentCulture)">@project.Name(currentCulture)</a>
}
