Hey all

How do i get only a list of published langauges for a page (langauges that are available to front end user).

var xxxxx = currentPage as ILocalizable;

xxxxx.ExistingLanguages

Seems to return me all langauges even language's the page has only been created in although not published.

currentPage.ExistingLanguages.Select(x => x.Name); is the same.

Thanks

Minesh

Hi,

Can you please try this-

var contentLoader = ServiceLocator.Current.GetInstance<IContentLoader>();
var startPage = contentLoader.Get<StartPage>(ContentReference.StartPage);
var published = contentLoader.GetChildren<PageData>(startPage.ContentLink)
                                // skip container pages
                                .Filter(new FilterTemplate())
                                // skip unpublished pages
                                .Filter(new FilterPublished())
                                // ...
                                .ToList();

using EPiServer.Filters;

....

PageDataCollection myPages = GetChildren(myParentPage);
new FilterPublished(PagePublishedStatus.Published).Filter(myPages);

GetChildren() might not be the most optimal way to get other language branches for the current page. That method is travelling page tree..

Ive opted going down this route,

var availablePageLanguages = FilterForVisitor.Filter(pageLanguagesBranches).OfType<PageData>();
var currentPageLanguages = availablePageLanguages.Select(page => page.Language.Name).ToList();

Glad you found the resolution

Not sure whether there is ready made method for this, but this could be the closest I could get to:

var pages = currentPage
    .ExistingLanguages
    .Where(l => l != currentPage.Language)
    .Select(l => _loader.Get<StartPage>(currentPage.ContentLink.ToReferenceWithoutVersion(), l))
    .Where(p => p.Status == VersionStatus.Published);

don't copy AS-IS ;) just an example from my experiments with StartPage

An alternative is to use IContentVersionRepository, pseudo code:

var publishedVersions = currentPage.ExistingLanguages.Select(x => _contentVersionRepo.LoadPublished(currentPage.ContentLink, x.Name));

var published = _contentLoader.GetItems(publishedVersions.Select(x => x.ContentLink), new LoaderOptions()).OfType<YourContentType>();

and depending on your requirements you might need to exclude page in current language (if you are looking only for published pages in other languages).

@QUAN would your approach perform better than

            var pageLanguagesBranches = contentRepository.GetLanguageBranches<PageData>(currentPage.ContentLink).ToList();
            var availablePageLanguages = FilterForVisitor.Filter(pageLanguagesBranches).OfType<PageData>();
            var currentPageLanguages = availablePageLanguages.Select(page => page.Language.Name).ToList();

There is no way to say for sure, unless you profile it. But

GetLanguageBranches

gets each language branch individually, so if you have many languages, it looks like it will be slower than my suggestion
