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.
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.
# File lib/sequel/plugins/touch.rb, line 61 def inherited(subclass) super subclass.touch_column = touch_column subclass.instance_variable_set(:@touched_associations, touched_associations.dup) end
Add additional associations to be touched. See the :association option of the Sequel::Plugin::Touch.configure method for the format of the associations arguments.
# File lib/sequel/plugins/touch.rb, line 70 def touch_associations(*associations) associations.flatten.each do |a| a = {a=>touch_column} if a.is_a?(Symbol) a.each do |k,v| raise(Error, "invalid association: #{k}") unless r = association_reflection(k) touched_associations[r.dataset_method] = v end end end
