yeah, easier though:
on item controller:
config.columns[:item_type].form_ui = :select
on item helper:
def options_for_association_conditions(association)
if association_name = :item_type
{'item_types.animal' => @record.thing_type}
else
super
end
end
Then you handle the meows, wuffs and moooos in a separate controller
using another model say, item_types, and cat, dog, cow, whatever in a
column named animal for this example.
There's another way to get it if you just need some static options:
form_column_override. Check the wiki for that
