|
touch_column | [RW] | The column to modify when touching a model instance, as a symbol. Also used as the default column when touching associations, if the associations don‘t specify a column. |
touched_associations | [R] | A hash specifying the associations to touch when instances are updated or destroyed. Keys are association dataset method name symbols and values are column name symbols. |
Set the touch_column for the subclass to be the same as the current class. Also, create a copy of the touched_associations in the subclass.

Add additional associations to be touched. See the :association option of the Sequel::Plugin::Touch.configure method for the format of the associations arguments.
