Feather: Filter by category or tag

If your controller has an action named ListByTaxon with first parameter Telerik.Sitefinity.Taxonomies.Model.ITaxon then Feather invokes this action, if a category or a tag matches the URL segment after the page URL.

You can optionally have a second parameter of type int? that you can use for paging.

The following declaration that uses this convention:

public ActionResult ListByTaxon(ITaxon taxonFilter, int? page)

Feather first tries to match a category, then it fallbacks to tags. When an item matches, the action is invoked with the matching taxon.

The following sample implementation filters NewsItems:

public ActionResult ListByTaxon(ITaxon taxonFilter, int? page)
   {
       var manager = NewsManager.GetManager();
 
       string fieldName;
       if (taxonFilter.Taxonomy.Name == "Categories")
           fieldName = taxonFilter.Taxonomy.TaxonName;
       else
           fieldName = taxonFilter.Taxonomy.Name;
 
       var items = manager.GetNewsItems().Where(n => n.GetValue<IList<Guid>>(fieldName).Contains(taxonFilter.Id) && n.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live).ToList();
 
        return View("Index", items);
   }
