Phillip , my inventory_controller.rb:
class InventoryController < ApplicationController
def index
@albums=Album.find(:all)
@cart=find_cart
end
def add_to_cart
itemType=params[:itemType]
productId=(params[:id]) #parameter passed in from "add to
cart" submission, it's either 1 or 2 in this case
if itemType=='album'
product_temp=Album.find(productId)
dest='/inventory'
end
if itemType=='dvd'
product_temp=Dvd.find(productId)
dest='/inventory/dvd'
end
product=Product.new(itemType,product_temp.title,product_temp.price)
@cart=find_cart
@cart.add_product(product) #add the album to the cart in
the sessions
redirect_to dest
end
def check_out
@cart=find_cart
redirect_to '/inventory/checkOut'
end
def review
@cart=find_cart #for shopping car display in the sidebar
@title=(params[:title])
@itemType=(params[:itemType])
if @itemType=='album' #must be a better way to reduce the amount of
redundant code
@album=Album.find_by_title(@title)
@review=Review.new
@[EMAIL PROTECTED] #Review.find(:all, :conditions => ["album
= ?", @title])
end
if @itemType=='dvd'
@dvd=Dvd.find_by_title(@title)
@review=Review.new
@[EMAIL PROTECTED] #Review.find(:all, :conditions => ["album =
?", @title])
end
end
def dvd
@cart=find_cart
@dvds=Dvd.find(:all)
end
end
my application.rb:
# Filters added to this controller apply to all controllers in the
application.
# Likewise, all the methods added will be available for all controllers.
class ApplicationController < ActionController::Base
helper :all # include all helpers, all the time
# session :session_key => '_inventory_session_id'
# See ActionController::RequestForgeryProtection for details
# Uncomment the :secret if you're not using the cookie session store
protect_from_forgery # :secret => '33dad663a17f28eb93b293523bcb06f2'
def find_cart
unless session[:cart] # if there's no cart in the session
session[:cart] = Cart.new # add a new one
end #for the unless
session[:cart] # return existing or new cart
#session[:cart] ||=Cart.new #creates 1 cart session
#can also be written more efficiently as above
end
def empty_cart
session[:cart]=nil
redirect_to '/inventory'
end
def find_cart
unless session[:cart] # if there's no cart in the session
session[:cart] = Cart.new # add a new one
end #for the unless
session[:cart] # return existing or new cart
end
def log_out
session[:login]=nil
redirect_to '/inventory'
end
end
find_cart is in application.rb and is used by many of the methods in my
inventory_controller file. for some reason it doesn't pull up any data when
in the check_out method....
