is database locking enabled by default in rails? -


some frameworks opinionated when comes database locking. example, grails orm (gorm) documents state following:

by default gorm classes configured optimistic locking

source: https://grails.github.io/grails-doc/latest/guide/gorm.html#locking

i've read through material online rails , understanding rails not provide locking default.

what rails default approach locking?

note: not question approach best, question confirm rails's approach locking.

by default, i'm pretty sure database locking turned off in rails. if want use locking, have @ ruby on rails docs:

http://api.rubyonrails.org/classes/activerecord/locking/pessimistic.html
