Enforcing that childitems without language version are not returned

Question

I have a menu container that contains link items. The menu container is just a container so it does not need to have separate versions in all the active site languages. More specifically, it will always only contain a version in english. The childitems however need to have separate versions in the active languages and there should be no language fallback if an item does not have a version in a language.

The code:

var mainMenuContainer = menuContainer.Children.FirstOrDefault(ch => ch.Name == MAINMENU_ITEMNAME);

So the mainMenuContainer will have the english language.

Then I do:

    var mainNavItems = mainMenuContainer.Children.Where(m => m.TemplateID == Constants.LinkItemTemplateId); 

How could I enforce that this call only returns child items that have a version in the context language? Maybe I could do something like

 foreach (var language in item.Languages)
 {
     var langSpecificItem = MasterDb.GetItem(item.ID, language);

     if (langSpecificItem.HasVersion())
     {

     }
}

but this seems not to be a terribly efficient way. I see that I could also check the IsFallback property of each item, but that seems not to be very elegant.

Answer 1

var mainNavItems = mainMenuContainer.Children.Where(m => m.TemplateID == Constants.LinkItemTemplateId && m.Versions.Count > 0); 

Where: m.Versions.Count > 0 is the new bit.

Items don't have language versions, only field values do. Add the above to your LINQ expression and you're good to go.

There is a new functionality, EnforceVersionPresence that also does this on a data layer level - but I highly recommend you do not use it. You'll basically have to "break off" your API from standard implementations to "Enforced" which could make it less portable.
