NameError in StoreController#add_to_cart
uninitialized constant StoreController::Cart
This is the controller:
class StoreController < ApplicationController
def index
@products = Product.find_products_for_sale
end
def add_to_cart
@cart = find_cart
product = Product.find(params[:id])
@cart.add_product(product)
end
private
def find_cart
session[:cart] ||= Cart.new
end
end
Amd this is the model
class Cart
attr_reader :items
def initialize
@items = []
end
def add_product(product)
@items << product
end
end
Thanks for the help

Can you add items to the cart in the console? This is wild speculation, I''ve never made an app with a cart, but seems like you might need a has_many :items, :class_name => ''products'' in the Cart model?

maybe your file name is Cart.rb instead of cart.rb Marnen Laibow-Koser-2 wrote:> > > NameError in StoreController#add_to_cart > > uninitialized constant StoreController::Cart > > This is the controller: > > class StoreController < ApplicationController > def index > @products = Product.find_products_for_sale > end > > def add_to_cart > @cart = find_cart > product = Product.find(params[:id]) > @cart.add_product(product) > end > > private > > def find_cart > session[:cart] ||= Cart.new > end > > end > > Amd this is the model > > class Cart > attr_reader :items > > def initialize > @items = [] > end > > def add_product(product) > @items << product > end > end > > Thanks for the help > -- > Posted via http://www.ruby-forum.com/. > > > > >-- View this message in context: http://www.nabble.com/Uninitialized-constant-%28controller-model%29-tp18392649p26123953.html Sent from the RubyOnRails Users mailing list archive at Nabble.com.
