Запазването не работи, разпръснете персонализиран метод

Работя върху моето приложение spree rails и по някакви причини правя някои персонализирани методи. Създадох нов и create методи в ProductsController, но последният не работи правилно, не записва данните в моята DB и не мога да разбера защо.

Това е моят контролер:

module Spree
  class ProductsController < Spree::StoreController
    before_action :load_product, only: :show
    before_action :load_taxon, only: :index

    rescue_from ActiveRecord::RecordNotFound, :with => :render_404
    helper 'spree/taxons'

    respond_to :html

    def index
      @searcher = build_searcher(params.merge(include_images: true))
      @products = @searcher.retrieve_products
      @taxonomies = Spree::Taxonomy.includes(root: :children)
    end

    def newproduct

      @product = Product.new();

      #render '/spree/home/newproduct'

    end

    def createproduct

      @name = params[:product][:name];
      @description = params[:product][:description];


      @product = Product.new({
                                 :id => 4,
                                 :name => @name,
                                 :description => @description});

      @product.save();

      if @product.save()
        redirect_to "/tutienda", :notice => "El producto ha sido insertado";
      else
        render '/spree/products/newproduct'
      end

    end

    ######################################################################################################

    def show
      @variants = @product.variants_including_master.active(current_currency).includes([:option_values, :images])
      @product_properties = @product.product_properties.includes(:property)
      @taxon = Spree::Taxon.find(params[:taxon_id]) if params[:taxon_id]
    end

    private
    def accurate_title
      if @product
        @product.meta_title.blank? ? @product.name : @product.meta_title
      else
        super
      end
    end

    def load_product
      if try_spree_current_user.try(:has_spree_role?, "admin")
        @products = Product.with_deleted
      else
        @products = Product.active(current_currency)
      end
      @product = @products.friendly.find(params[:id])
    end

    def load_taxon
      @taxon = Spree::Taxon.find(params[:taxon]) if params[:taxon].present?
    end
  end
end

И моите методи са newproduct и createproduct. Дори опитах whitn и abort преди @product.save, за да видя какво има в обекта и обектът има данните, но след това DB не ги получава. (съжалявам за лошия ми английски).
