On here: http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-check_box-label-Gotcha
you see this code: <%= fields_for "project[invoice_attributes][]", invoice, :index => nil do |form| %> <%= form.check_box :paid %> ... <% end %> why are they using :index => nil in the example? I mean I know that what it does is ensure that the invoice objects do not get passed an index number so that you have this: project[invoice_attributes][] rather than this: project[invoice_attributes][1]. But why in the above example, do they want to achieve this? It seems as though invoice is an existing object and therefore is not a new record. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
