Attributes

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.

Public Instance methods

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.

  subclass.touch_column = touch_column
  subclass.instance_variable_set(:@touched_associations, touched_associations.dup)

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