[Rails] Editing an object with associations

[David Heinemeier Hansson]

>> So to restate your problem.  An employee has many phone numbers, phone
>> numbers belong to a PhoneNumberType.   You want to edit the employee &
>> their phone numbers & their types in one page?

I think something like this would work:

View:
   <% @employee.phone_numbers.each do |@phone_number| %>
     <%= collection_select "phone_number[]", "phone_number_type_id", 
PhoneNumberType.find_all, :id, :name %>
     <%= text_field "phone_number[]", "number" %>
   <% end %>

Controller:
   @employee.phone_numbers.each_with_index do |phone_number, idx|
     phone_number.update_attributes(@params[:phone_number][idx])
   end

P.S.: The Ruby naming convention for variables is underscored, not 
camel case.
