Provides a way to honor the :conditions on an association while searching the association’s klass
# File lib/active_scaffold/helpers/association_helpers.rb, line 5 def association_options_find(association, conditions = nil) relation = association.klass.where(conditions).where(association.options[:conditions]) relation = relation.includes(association.options[:include]) if association.options[:include] relation.all end
returns options for the given association as a collection of [id, label]
pairs intended for the options_for_select
helper.

A useful override for customizing the records present in an association dropdown. Should work in both the subform and form_ui=>:select modes. Check association.name to specialize the conditions per-column.
