help modifying site.tags data

[alexellison]

Because we're storing press release and products in collecitons as opposed to keeping them in the _posts dir where blogs sit, the tags specified in their frontmatter are not making it into the site.tags variable.

In order to get the tags specified by collection items (in addition to _posts) added to the site.tags hash I started writing some custom code that, but could not successfully modify the site.tags element.

@levelos check out the tags-from-collections branch and see my latest commit (5d06346a038691c149fb5c5a0917c0812857e65f) for the first try at modifying site.tags.

Going to close this one out as discussed. It may not be a requirement and won't work as we intend because site.tags is a method, not a property. The code snippet below would work, for posterity.

  class CollectionTags < Generator
    def generate(site)
      site.collections.each do |key, collection|
        collection.docs.each do |item|
          if item.data['tags']
            item.data['tags'].each do |tag|
              site.tags << tag
            end
          end
        end
      end
    end
