There are multiple places where we use conditions like "where(1=0)" or "where(id<0)" etc. because we want to preserve the active relation object. Since Rails 4 there is `none` method that achieves the same goal with null object pattern, so the eventual query won't even be sent to the DB - https://api.rubyonrails.org/classes/ActiveRecord/QueryMethods.html#method-i-none
