Episode 73 of Ryan Bate's great series of screencasts shows an example of using fields_for to create a new record containing two models. I'm trying to repeat his result but alway get and error from this line:
<% fields_for "ferry[scheduled_port_attributes]", scheduled_port do |sp_form| %>
In the rails cast, this returns an array of scheduled_port_attributes, but instead I get a hash with "3" as a key:
{"commit"=>"Save", "ferry"=>{ "scheduled_port_attributes"=>{"3"=>{"departs(4i)"=>"21", "departs(5i)"=>"29", "arrives(1i)"=>"2007", "arrives(2i)"=>"10", "port_id"=>"2", "arrives(3i)"=>"12", "arrives(4i)"=>"21", "departs(1i)"=>"2007", "arrives(5i)"=>"29", "departs(2i)"=>"10", "departs(3i)"=>"12"}}, "id"=>"1"}}
Am I missing something? I'm on edge rails. Does that matter?
