update_columns(attributes) public

Updates the attributes directly in the database issuing an UPDATE SQL statement and sets them in the receiver:

user.update_columns(last_request_at: Time.current)

This is the fastest way to update attributes because it goes straight to the database, but take into account that in consequence the regular update procedures are totally bypassed. In particular:

This method raises an +ActiveRecord::ActiveRecordError+ when called on new objects, or when at least one of the attributes is marked as readonly.
