Hello everyone, I''m a complete Rails newbie who is currently working my way through the Agile Web Dev with Rails book. I''ve reached the chapter on creating the shopping cart (chapter 8). I keep having a problem with the same error which I can''t get past, however what''s more confusing is that it''s being generated even when I swap all my app code out

Hello, Im in the process of working my way through the 2.ed of the agile book. As many of you already know, the book goes through the regular development cycle of the Depot application. I have hit a wall when they started talking about the sessions and the exact mechanics of how an item is added to the session. The code looks like this: depot/app/controllers/store_controller: def add_to_cart

Hello, I should give the expected disclaimer that I am brand new to rails and am going through the Agile web development with Rails book right now. I am in the testing section and I can''t get past an error. this is my cart_test.rb test file: require File.dirname(__FILE__) + ''/../test_helper'' class CartTest < Test::Unit::TestCase fixtures :products def setup

Hello, Im trying to understand how this helper method works: def hidden_div_if(condition, attributes = {}) if condition attributes["style"] = "display: none" end attrs = tag_options(attributes.stringify_keys) "<div #{attrs}>" end This is how they are calling it: <%= hidden_div_if(@cart.items.empty?, :id => "cart") %>

I have been working through the Agile Web Development with Rails book doing the Depot tutorial. I have completed it and it works but I cant say I understand how and why. My question is this "After adding products to the Cart, how do I then give users the option to delete just one item and not empty the whole cart?" I''ve been playing around with all sorts of code, just making

I''m working my way through the book Agile Web Development with Rails, and I am in the section where the book has me creating a display_cart method and the associated view. When I copied the code from the book into the view, it threw this error. If anyone could give me some hints where I should be looking I''d appreciate it. NoMethodError in Store#display_cart Showing

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

Hi I get to about page 103 of the book and get an application error. Further investigation reveals the following error in the dev log: Mysql::Error: #42S22Unknown column ''id'' in ''where clause'': UPDATE sessions SET `data` =

This is kind of frustrating (but no doubt helpful in the long run) that after following along and coding , and d/l the code the same error is appearing. For those who are familiar with the depot app, I''ve run into a problem after fixing the cart to reflect quanitites. I worked through the intended error messages but now have this appearing: SyntaxError in StoreController#add_to_cart

I''m new to Ruby and RoR but excited to learn what I can do with RoR; I have Pickaxe second edition and want to get "Agile Web Development with Rails" but I''m aware that the book was published some while before RoR version 1.0 was released. Has a lot changed since then, and would I therefore be advised to wait for a second edition of AWDwR? Many thanks in advance

Hello, I have a time-series of standards measured for Refractive index. They are daily standards, however, I didn't run one everyday so some days have no data. I can plot the values, but the x-axis does not represent the correct time series (i.e. it's just an evenly spaced 1,2,3 type axis). I want to plot the points with some form of representitive date line on the x-axis. I don't

My question is with regards to keeping things DRY. When the user goes to "view cart", that page needs to display the cart, then the cart display needs to update with AJAX calls when items are added from that page. It would

anyone can explain me why in the Agile Depot Tutorial application they use i.product_id to find if a product already exist in the cart, because the cart contains items, each of them references a product. I tried i.product_id like in the tutorial and i.product.i all of these 2 notation works , but i find the second seems more clean??? isn''t it. Any explanation will be fine Regards
