module Sequel::Plugins::ColumnsUpdated
The columns_updated plugin stores the columns hash used in the UPDATE query
when saving the instance, and makes it available in the after_update and
after_save hooks via the columns_updated
accessor. The data
is cleared before returning from save
.
Usage:
# Make all model subclasses store the columns hash used for updating Sequel::Model.plugin :columns_updated # Make the Album class store the columns hash used for updating Album.plugin :columns_updated
