similar to: new to rails; problem with testing section in Agile book

When I run the unit testing code in Unit Testing Models chapter of the Agile Rails book, I get the following error: $ ruby test/unit/cart_test.rb Loaded suite test/unit/cart_test Started F. Finished in 0.21806 seconds. 1) Failure: test_add_duplicate_product(CartTest) [test/unit/cart_test.rb:22]: <4690> expected but was <3579>. 2 tests, 3 assertions, 1 failures, 0 errors require

In the page 148 of the AWD book it''s mentioned that the while testing @products and @version_control_book are automatically made available. That''s not the case with me. In my test environment I don''t get those two variables. I was wondering if anything has changed in Rails 1.1 because in the new edition of the book (AWD - edition 2) there is no mention of such

Here is my products.yml version_control_book: id: 1 title: Pragmatic Version Control description: How to use version control image_url: /images/sk_svn_small.jpg price: 29.95 date_available: 2005-01-26 00:00:00 automation_book: id: 2 title: Pragmatic Project Automation description: How to automate your project

Hi all, I get an error when testing the "store_controller_test.rb" The troublesome line is in the test below: def test_add_to_cart get :add_to_cart, :id => @version_control_book.id <<< cart = session[:cart] assert_equal @version_control_book.price, cart.total_price assert_redirected_to :action => ''display_cart'' follow_redirect

This is a newbie question, I have a class which is not derived from ActionController or ActiveRecord but I want to use logging, I tried require but still logging does not work - This class is located in a file in "model" directory. ------------------------------------ require ''logger'' class Cart def add_product(product) logger.info("Searching for product

I''m doing the depot example in the Agle Web development book. I''m getting this error: "undefined method `product'' for #<BigDecimal:331ce70,''0.21E1'',8(8)> " "Extracted source (around line #9): 8: for item in @items 9: product = item.product 10: -%> 11: <tr> 12: <td><%= item.product%></td>"

I want to use something similar to the following: @total_price += { product.price <> nil ? product.price : 0.0 } This fails in rails with a "nil can''t be coerced into Float" error. What is the (most) correct way to do this? On a related issue, what is the significance of the value 40 following "cart.rb" in the trace snippet below? The entire class file

Hi, I am just learing Rails and I am going through the Agile Web Development with Rails book. I am receiving: NoMethodError in Store#add_to_cart undefined method `add_product'' for #<StoreController:0x3764d80> RAILS_ROOT: ./script/../config/..

Working my way through chapter 8 of "Agile Web Development...", I''m getting the following error when clicking the add_to_cart button. ArgumentError in Store#add_to_cart wrong number of arguments (0 for 1) What am I doing wrong? I know it''s got to be some thing stupid. Request: Parameters: {"id"=>"1"} session dump: --- :cart:

Hello! I am working my way through the Agile Web Development guide on RoR (the depot application). I am a bit lost as to where to debug the following error. The error is pasted below: ================================================================================================ NameError in Store#add_to_cart undefined local variable or method `product'' for LineItem:Class

I''m following Agile Edition 1. On page 148 it suggests using instance variables named after the fixture, for example: assert_equal @version_control_book.id, @product.id When I introduce this type of instance variable into my test, I get the following error: 1) Error: test_not_owner(GroupTest): RuntimeError: Called id for nil, which would mistakenly be 4 -- if you really wanted the

I bought the second edition of the ruby on rails, it seems to work fine now, did some adjustments to the code. But now I get a second error and I want to learn to understand to fix them myself. So here is the error. ArgumentError in StoreController#add_to_cart wrong number of arguments (1 for 0) #{RAILS_ROOT}/app/models/cart.rb:15:in `initialize'' #{RAILS_ROOT}/app/models/cart.rb:15:in

While running the product_test.rb test fixture in the Agile Web Development book (p. 148), but when I run ruby test/unit/product_test.rb, I get the following error: 1) Error: test_read_with_hash(ProductTest): NoMethodError: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occured while evaluating nil.[]

In the Agile Rails tutorial I am revisiting building a cart. I have followed the steps given in the book to create the class ''Cart'' thus: class Cart attr_reader :items attr_reader :total_price def add_product(product) @items << LineItem.for_product(product) @total_price += product.price end def initialize @items = [] @total_price = 0.0 end

I''m fairly new to Rails, and I''ve been learning from AGILE WEB DEVELOPMENT WITH RAILS. Everything has been going smoothly until the chapter on Unit Testing, where I''m getting some strange errors. I''m up to page 141 in the Agile book, and attempting to run the test program containing the method test_read_with_hash. The previous tests work properly, but I

When I add an item to the shopping cart, I get an error: undefined local variable or method `cart_item'' for #<#<Class:0x3715a78>:0x3715a48> Session info says the cart being updated properly. I''m just not able to output two variables: <%= cart_item.quantity %> &times; <%= h(cart_item.title) %> I did some research, and I can grasp that local

I''m working on building the shopping cart in the Depot tutorial in the Agile Web Development book. I''m at the part (about page 80) where you build the ability to add items to the cart. I''m able to get to /store/display_cart/ and it seems items are being added, but if I just click on a link to add an item (/store/add_to_cart/2) it gives me this: NoMethodError in

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] ||=
