similar to: Railscast 75, Observe_field and Shopping Cart

I am using this line on my index.rhtml page to capture the quantity required of a particular item for a basic shopping cart app: <%= text_field ''line_item'', ''quantity'', {:size=>3} %> </td> but my next screen (a cart screen) doesn''t reflect what was entered in that text field when the item is added to the cart. That is,

This might seem really simple to some but just wanted to ask: what is the difference between @session[''user''] and session[:user] ? and how would you use each? And another question, I have the following code: def get_customer if @session[''customer''] @c = Customer.find(@session[''customer'']) end end private def

We''re currently looking for volunteers on the new RailsCart[1] project. The idea is to build something relatively simple with all of the features that most open source shopping carts seem to be missing. We''ll be using ActiveMerchant for all of our payment gateway needs. We''re not trying to build the ultimate shopping cart. This is designed for Rails developers who need

Hi there, I''m at a loss... I was on the #ROR channel last night and spoke to a really helpful person (Defiler) who gave me some direction on building a shopping cart. Unfortunately, I wasn''t able to successfully get to where I need to go. This is the predicament I am currently finding myself in: I''m building a shopping cart for a client''s new website. They

hi, i''m having a little trouble rendering a partial that uses a remote_form_for and is in another controller. <%= render :partial => "reviews/new"-%> and in the partial i have only this, inside another controller <% remote_form_for @review do |rv|-%> <%= rv.hidden_field :value, :value => 1 -%> <%= rv.image_submit_tag "thumbsupnc.png" %>

Hi all, just joined and have only just kicked off with Rails (coming, but not departing, from WebObjects development). And so far there seems to be a lot of promise except for one thing I can''t figure out as yet -- the above problem. Say I have the following conceptual relationships: ITEMS <<--->> CARTS i.e., each item can belong to one or more categories. So really

Hi, im looking to build a page similar to a shopping cart page. When you change the ''price'' or ''quantity'' fields, the total is calculated and displayed. There are other fields in the form which have no relation to this action. So i guess observe_form is not required. Can someone tell me what the best practise is for this?

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` =

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 want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

I recently got a copy of the second addition in PDF and got stuck on the Ajax portion using highlighting page 128. While trying to make my cart flash I got an RJS error when I click add to cart. I have gone back and made sure my code matched what was in the book but no help. I sent Dave an email and he rec''d this list. Anybody got any good links for troubleshooting Ajax or maybe have see

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 got the dragging to work, and the adding the to cart , but i''m having a problem drag from with the cart div it doesn''t drag. But the dragging works on the cart (url) here is a quick example of the cart http://64.90.176.114/ajax/drag.php - try dragging into the the solid line div (it will add an item to the db). but then try and drag from within the solid line div (gray

First of all id like to say hi to everyone from Argentina, im yet another Depot first-timer. Going through the example, i got to the point where my cart finally runs Ajax-based. And there is a line where Dave says, after all the job is done "You should see the cart in the sidebar update. And you shouldn''t see your browser show any indication of reloading the page. You''ve

All, does any one has a drag and drop sample code using rails and ajax that I can use as a starting point for mine? I ''ll for customers to drag and drop item being purchase into their shopping cart. Thanks Patrick

Hi, I''m developing an application which has to manage many types of products. But I can''t think what the best approach in rails is on how to implement them. Here is a selection of some of the products (with some data types) that the software will have to manage: Speaker Make - String Model - String Wattage - Integer Price - Decimal

Dear all, I have a general form (which I generate via form_tag) for a ''subscription''. Inside this form the user can add ''elements'' to his subscription. I do this with an an additional Ajax form: <% form_remote_tag :url => { :action => :add_to_cart, :id => element } do%> <%= submit_tag "Add" %> <% end %> Every time 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

I am really new to Ruby and Rails but as you probably see I am trying to get the shopping card working from the book. I am getting this error but I really don''t know what to do. I have looked up several of topics that stated the same problem but as far as I am, nothing has helped me out yet. Is there something wrong with the Product model? This is in the StoreController and I believe it
