I would use inheritance (STI) in that case, with a type column:
Customer
Company < Customer
Person < Customer
And then I would use two scaffolds, one for company and other for person,
probably including a module with common active_scaffold configuration.
Anyway you can use onchange event in the select, and in the event show or hide
the fields you want, using the clases for example:
function change_customer_type(event) {
$$('.company_field_1-input, .company_field_2-input,
.company_field_3-input,
.company_field_4-input').each(function(item) {
item.up('li').call(this.value == 'company' ? 'show' : 'hide');
});
$$('.person_field_1-input, .person_field_2-input, .person_field_3-
input').each(function(item) {
item.up('li').call(this.value == 'person' ? 'show' : 'hide');
});
}
