Noindex deal criteria - i.e. instruct search engines to ignore deals (and remove from index) and *not* publish in xml sitemap.

gistfile1.rb

# Deal types currently included in xml sitemap
#  * "LocalDeal", "EscapesDeal", "AtHomeDeal", "FamiliesDeal"
#  * live event deals are included
# URLs are generated with LS::Routing
#  * Need to support a mobile version of the url for alternate content and mobile sitemap in near future.
def search_engine_ignore?(deal)
  deal.exclusive? || deal.boomerang? || !deal.active?
end

#  this logic expands to
def search_engine_ignore?(deal)
  # deal.exlusive?  - bitfield in deals db. name defined in LS::Deals
  # deal.boomerang? - DealEvergreenPreferece is associated to Deal as has_one in deals db.
  # deal.active?    - current time is within the overall deal runtime AND all options are available for purchase and !sold_out
  deal.exclusive? || deal.deal_evergreen_preference.present?
    || !(((!!(deal.offer_starts_at && deal.offer_ends_at)) && deal.offer_starts_at <= Time.current && Time.current < deal.offer_ends_at) && !(deal.options.select(&:available_for_purchase).all?(&:sold_out?)))
end
