| * | | | | | ActiveRecord::Relation#blank? should `LIMIT 1`David Celis2013-06-071-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an SQL improvement to ActiveRecord::Relation#blank?. Currently, it calls `to_a` on the Relation, which loads all records in the association, and calls `blank?` on the loaded Array. There are other ways, however, to check the emptiness of an association that are far more performant. `#empty?`, `#exists?` and `#any?` all attach a `LIMIT 1` to the SQL query before firing it off, which is a nice query improvement. `#blank?` should do the same! Bonus performance improvements will also happen for `#present?`, which merely calls the negation of `#blank?` Signed-off-by: David Celis <me@davidcel.is>
