Suppose the User model defines a column like this and does not have lock_version
class DeviseCreateUsers < ActiveRecord::Migration[5.1] def change create_table :users do |t| t.string :name # do not have a lock_version and other optimistic locks end end end
When executing User.locking_column, I thought that I would return nil because This Model does not have locking_column, but return “locking_column”.
Would you like to submit a PR that returns nil if there is no problem?
