Rails cocoon f.fields_for not working

Question

I'm working with a project that requires nested forms to add multiple valves to a single order (order is called rfq in this case).

I get this error:

ActionView::Template::Error (uninitialized constant Rfq::Valf):
    48:   </div>
    49:
    50:   <div id="valves">
    51:     <%= f.fields_for :valves do |valve| %>
    52:       <%= render 'valve_fields', f: valve %>
    53:     <% end %>
    54:       <%= link_to_add_association 'add valve', f, :valves %>

Here's relevant part of the form partial,

<%= form_for @rfq do |f| %>
...
  <div class="field">
    <%= f.label :application %><br>
    <%= f.text_field :application %>
  </div>

  <div id="valves">
    <%= f.fields_for :valves do |valve| %>
      <%= render 'valve_fields', f: valve %>
    <% end %>
      <%= link_to_add_association 'add valve', f, :valves %>
  </div>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

Valve fields partial:

<div class="nested-fields">
    <div class="field">
        <%= f.label :line %>
        <%= f.text_field :productline %>
    </div>
    <%= link_to_remove_association "remove valve", f %>
</div>

RFQ model:

class Rfq < ActiveRecord::Base
    has_many :valves
    accepts_nested_attributes_for :valves, :allow_destroy => true
    belongs_to :customer
    has_paper_trail
end

Valve model:

class Valve < ActiveRecord::Base
    belongs_to :rfq
    has_paper_trail
end

Thanks in advance

Answer 1

Try specifying your "Valve" class name as illustrated below.

class Rfq < ActiveRecord::Base
  has_many :valves, :class_name => "Valve"
  accepts_nested_attributes_for :valves, :allow_destroy => true
  belongs_to :customer
  has_paper_trail
end
