similar to: re: Maintaining same session for a user across

Hi, I''m trying to make a simple shopping cart, where I want to maintain state when a use logs in from different location. Consider the following : 1. ''foo'' logs in from home pc and add ''bar'' item to the cart. 2. ''foo'' goes to office and logs in from office PC. 3. Now I want only one session for ''foo'', so that when

I am implementing a system for users to easily create a small shop for themselves. And I''ve run into a route problem. NOTE: I''ve removed a lot from my route.rb file, since I want focus on this particular problem. :-) I currently have a route.rb like this: ActionController::Routing::Routes.draw do |map| map.resources :shops do |shops| shops.resource :cart, :member => {

We''re going to have problems keeping cookies across domains. We want people to shop in one domain (e.g. "booksareus.com") and then checkout on the same server securely under a different domain (e.g. "greatbooks.com"). When we make the jump to the secure domain (the checkout link) can we submit the user''s session ID along with it and have it

Many of you probably know the ''depot'' app from the ''Agile Rails development'' book. When the view changes from ''Store'' to ''display_cart,'' a session containing the shopping-cart (:cart) is supposed maintain the ''cart'' between calls, but when the display_cart stub view shows up, I have always ZERO elements

I want to be able to write a script in Ruby which regularly consumes an XML feed from a fixed source, re-formats it, produces a large file for web delivery, and updates a database with the contained information. It''s simple - just running a script from a cron job, and some basic data manipulation... But I''d prefer to use the Rails database mapping constructs than roll my

http://script.aculo.us/demos/shop if you drag an item from the product list straight to the droppable area to remove an item from the cart, it''ll still add it to the cart. -PJ

Hi all, I am writing a simple shopping cart which will consist of a single class. There will be no DB table for carts so I do not want to make my Cart a model. But where do I place my Cart class so that I can access it in my controllers? I want to be able do do things like this (for instance in a shop controller): def add_to_cart @session[''cart''].add(article_id, amount)

I''m working on an application that can be accessed from multiple domains. I want to maintain session data across these domains, such that if a user logs in at www.domain1.com, then moves to www.domain2.com, they will still be logged in with the same account. Is this possible in Rails? Could anyone point me towards a guide of how to achieve it? Many thanks, Adam

Hi all, I''m following the shop example in ''Agile Web Development with Rails''. I would like to extend the checkout screen, in such a way people can change the number of items they have selected in there cart. In my controller I have: def checkout @cart = find_cart @items = @cart.items if @items.empty?

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,

Hi all I''m creating a shop page. I have a cart model that looks like the following: class Cart attr_reader :line_items def get_line_item id @line_items.each do |l| return l if l.id == id end end def initialize @line_items = [] end def empty! initialize end def empty? return true if @line_items.empty? false end end And I have some

All, I''ve just started Rails and Ruby a week or so ago. Please forgive me for my ignorance. I started writing a small test application to test some of my new knowledge and have hit a wall. Would like some best practices. I have 3 tables, as below... CREATE TABLE `carts` ( `id` int(11) NOT NULL auto_increment, `name` varchar(255) NOT NULL, `quantity` int(11) NOT NULL, PRIMARY

I''m about to get hosting for an on-line shop application in the UK. I''m leaning towards Bytemark, as they seem to have the right product range and attitude. Support sound knowledgeable and helpful and they show a marked preference for Debian, which I happen to be fond of. Has anyone tried them? Has anyone had good or bad experiences with other hosting companies

.... I have a CentOS 5.n VM running on a Fedora 14 server/host, installed using virt-manager, pretty plain vanilla. I use it to compile binaries to run under RHEL/CentOS 5.n OS. I occasionally notice that when the VM gets paged out by the server, it takes several minutes to get it back in :-/ (see below).

Hi all I''ve coded a small shop that works well on my dev machine (OSX 10.5). But look at the following page: http://shop.incense.ch/compact_discs/1 When clicking "Reservieren", the page is forwarded to a new page, where the product is added to the shopping cart, and a flash notice is prepare. Then the page is redirected back to the shop page. On my dev machine this works

I am working on a resource planning problem. I like to use a nice drag and drop interface for that. E.g. have a box of persons and a box of projects, now I would like to assign a persom to project by dragging it from the available resources box to a recieving project box. I have studied the amazing drag and drop shopping card code listed here http://demo.script.aculo.us/shop What I need to

Hi All Not specifically a scriptaculous question, but I was wondering how people were going about maintaining access to their applications via standard urls. Say for example I''ve a shop at www.shop.com, and its pure ajax to load in products. Now customer A wants to show a friend a product on the site - giving him the url www.shop.com and telling him to click on a series of links

Many of you probably know the ''depot'' app from the ''Agile Rails development'' book. I have constructed the ''products'' model, the Store-controller, and the ''Cart'' and ''Line Item'' classes. I have told Application-controller about :cart and :line_item: model :cart model :line_item Here''s part of

All, There is an assertion in AWDWR that the in-memory session store is "too simplistic." However, I find myself nudged in this direction by the need to keep a non-serializable model attribute available in my session and the relative pain of implementing either a custom serialization scheme for the model in question (or a custom caching mechanism so that I can store my attribute
