In yesterday's post I said, in relation to "how does .present? work on ActiveRecord::Relation", I said that present? performs an existence check SELECT 1 AS one FROM ... LIMIT 1 because it calls exists? underneath. This is actually wrong - it loads the relation.

Jonathan Mast corrected me on Twitter. It turns out, I should have paid closer attention! Here is the actual implementation of blank? on ActiveRecord::Relation on Rails master:

# Returns true if relation is blank.
def blank?
  records.blank?
end
