ActiveScaffold can't guess what classes can act as entity.
The best way is add a field for entity_type and another for entity_id.
Set :select form_ui to entity_type, with Person and Organization as options.
Then add a form override for entity_id:
config.columns[:entity_type].form_ui = :select
config.columns[:entity_type].options[:options] = ['Person', 'Organization']
config.columns[:entity_type].update_column = :entity_id
#AccountsHelper
def account_entity_id_form_column(record, options)
select_options = if record.entity_type
record.entity_type.constantize.all.map {|r| [r.to_label, r.id]}
else
[]
end
select :record, :entity_id, select_options, options
end
