ruby on rails - Undefined method 'nested attribute' for model -

i'm trying to create 2 type of addresses: pick address , delivery address. created polymorphic address model associated listing , order. want create new address in listings , orders views using fields for. reason works when create listing, when try create order undefined method 'address' model order.

note: irrelevant code has been omitted snippets below.

address.rb

class address < applicationrecord  belongs_to :addressable, polymorphic: true, optional: true end 

listing.rb

class listing < applicationrecord  has_many :orders  has_one :pickup_address, as: :addressable, class_name: "address", dependent: :destroy   accepts_nested_attributes_for :pickup_address end 

order.rb

class order < applicationrecord  belongs_to :listing  has_one :delivery_address, as: :addressable, class_name: "address", dependent: :destroy   accepts_nested_attributes_for :delivery_address end 

in form views have

app/views/listings/_form.html.erb

<%= form_for(setup_listing(@listing)) |f| %>  <%= f.label :description %>  <%= f.text_area :description, class: 'form-control' %>   <%= f.label :price %>  <%= f.text_field :price, class: 'form-control' %>   <%= f.fields_for :pickup_address |u| %>      <%= u.label :city %>     <%= u.text_field :city, class: 'form-control' %>      <%= u.label :sector %>     <%= u.text_field :sector, class: 'form-control' %>      <%= u.label :line_1 %>     <%= u.text_field :line_1, class: 'form-control' %>      <%= u.label :line_2 %>     <%= u.text_field :line_2, class: 'form-control' %>     <% end %>  <%= f.submit "submit", class: "btn btn-primary" %> <%end%> 

app/views/orders/_form.html.erb

<%= form_for([@listing, setup_order(@order)]) |f| %>   <%= f.fields_for :delivery_address |u| %>    <%= u.label :city %>   <%= u.text_field :city, class: 'form-control' %>    <%= u.label :sector %>   <%= u.text_field :sector, class: 'form-control' %>    <%= u.label :line_1 %>   <%= u.text_field :line_1, class: 'form-control' %>    <%= u.label :line_2 %>   <%= u.text_field :line_2, class: 'form-control' %>    <% end %>  <%= f.submit "submit", class: "btn btn-primary" %> <%end%> 

note in order form_for function use square brackets because build order listing.

routes.rb

rails.application.routes.draw   resources :listings      resources :orders   end end 

the setup_order/listing function comes from

app/helpers/form_helper.rb

 module formhelper      def setup_listing(listing)       listing.build_pickup_address if listing.pickup_address.nil?       listing     end      def setup_order(order)        order.build_delivery_address if order.delivery_address.nil?        order     end   end 

which use create new address in case 1 not exist suggested in this tutorial.

i made sure add address attributes params in controllers

listings_controller.rb

  def create     @listing = current_user.listings.build(listing_params)     if @listing.save       flash[:success] = "listing created!"       redirect_to @listing     else       render 'new'     end   end    .    .    private    def listing_params    params.require(:listing).permit(pickup_address_attributes: [:city,   :sector,:line_1, :line_2])   end 

orders_controller.rb

   .    .    def create      @listing = listing.find(params[:listing_id])      @order = @listing.orders.build(order_params)      if @order.save        redirect_to listings_path      else       render 'new'      end    end    .    .    private     def order_params      params.require(:order).permit(delivery_address_attributes: [:city, :sector, :line_1, :line_2])    end 

again, creating listing works perfectly. problem happens when try create new order. in advanced!

after not finding answers problem diceded change relationship has_one has_many, setting default attribute name, see if error had changed.

class order < applicationrecord    belongs_to :listing   has_many :addresses, as: :addressable, dependent: :destroy    accepts_nested_attributes_for :delivery_address  end 

i made changes in controller , view, again getting no method 'address' instead of 'addresses' should have been. realize somewhere must have written address searched @eeeeeean suggested , indeed in validations (which omitted in questions considering them irrelevant) still had validation address, here actual code model.

class order < applicationrecord   validates :address, :seller_id, :buyer_id, :listing_id, presence: true      belongs_to :listing   belongs_to :buyer, class_name: "user"   belongs_to :seller, class_name: "user"    has_one :delivery_address, as: :addressable, class_name: "address", dependent: :destroy    accepts_nested_attributes_for :delivery_address    enum status: [ :ordered, :shipped, :delivered, :rated ]  end 

so avoid omitting code in questions , make sure check places wouldn't so.
