Rails: create two nested items in controller but only one shows in the view -


consider following:

customer.rb

module refinery     class customer < refinery::core::basemodel             has_many :users, :class_name => "refinery::user"        accepts_nested_attributes_for :users     end   end end

user_decorator.rb

refinery::user.class_eval   belongs_to :customer, :class_name => 'refinery::customer' end

customer_controller.rb

module refinery   class userscontroller     def new       @customer = ::refinery::customer.new       # tried using build here no sucess       @owner = @customer.users.new       @inputer = @customer.users.new        # raise @customer.users.length.to_yaml => returns 2 works!     end   end end

new.html.erb

<%= form_for @customer |f| %>   <% if @customer.errors.any? %>     <div id="error_explanation">       <h2><%= pluralize(@customer.errors.count, "error") %> need corrected before continuing:</h2>       <ul>         <% @customer.errors.full_messages.each |msg| %>         <li><%= msg %></li>         <% end %>       </ul>     </div>   <% end %>   <!-- company fields here -->   <%= fields_for :users |user| %>     <div>       <%= user.label :first_name %>       <%= user.text_field :first_name %>     </div>     <div>       <%= user.label :last_name %>       <%= user.text_field :last_name %>     </div>     <!-- more user fields here etc -->   <% end $> <% end %>

when view page 1 user shows up. ids fields also:

<div>    <label for="users_last_name">last name</label>    <input id="users_last_name" name="users[last_name]" size="30" type="text"> </div>

i think there should kind of index in there right? (i.e. 0, 1, 2 etc if iterating on array.

what doing wrong?

you missed 

f.fields_for

just add , should work
