Bucket Items and Glass Mapper Retrieving

Question

So I am trying to bring back a list of Bucket Items and map them using Glass Mapper.

A couple of issues I am running into. I tried as you can see using the News glass model, but I get back several thousand records instead of just the one I have now.

The records returned are empty. So that is probably incorrect. If you look at the count variable with that I get back two records one being the News item I expect and the other is the standard values of the News item. I believe I am on the right track as Bucket Items get put in the index, but not sure how to map this correctly to Glass Mapper. Any ideas?

using (var context = ContentSearchManager.GetIndex("sitecore_web_index").CreateSearchContext())
{
    var newsitems = context.GetQueryable<Models.sitecore.templates.Feature.News.News>().ToList();
    var count = context.GetQueryable<SearchResultItem>().Count(item => item.TemplateId == INewsConstants.TemplateId)
}

Answer 1

This is happening because in your first query, you are not filtering the results by anything:

var newsitems = context.GetQueryable<Models.sitecore.templates.Feature.News.News>().ToList();

Your query is returning all the Sitecore items in the index. But if your News template is setup to enforce the template on the Glass model, it will not be able to cast the Sitecore Item to your Glass model in the results that don't match the template.

Glass doesn't automatically apply a query to filter the search results by template Id.

You could add this in a couple of ways:

1. Just add the filter to the query:

   var newsitems = context.GetQueryable<Models.sitecore.templates.Feature.News.News>()
       .Where(item => item.TemplateId == INewsConstants.TemplateId)
       .ToList();
   

2. Add a predefined query to your model class:

   [PredefinedQuery("__templatename", ComparisonType.Equal, "news"]
   public class News 
   {
       // fields here
   }
   

This would then automatically add the template query anytime you used that class to return results from the search API.
