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

As a long-time author of computer books, fairly experienced MVC/OO thinker/coder, and recent Rails convert, it is probably not surprising that my midnight ruminations occasionally lead me to wonder if a Rails book might not be an interesting undertaking. But I know there are some great titles out there already and undoubtedly dozens more in the works. I''m interested in writing

I needed to format numbers with commas to make it more human readable. Here''s how I did it. def commify(number) c = { :value => "", :length => 0 } r = number.to_s.reverse.split("").inject(c) do |t, e| iv, il = t[:value], t[:length] iv += '','' if il % 3 == 0 && il != 0 { :value => iv + e, :length =>

It seems Rails sessions by default only last, well, a browsing session. If the Rails app keeps track of logged-in state by sessions, that state doesn''t survive restarting the browser. How best to change this behaviour, to make the session cookie live forever, or at least beyond browser restarts? It was suggested to me on IRC to combine sessions with code to generate a unique id and

Hi, My application has a table of People that has information about them, and I want to have a subset of those people as Users - people that can login to the application. What is the best way to do this? Add columns to People that only Users would use? I''ve read the threads on single table inheritance, but it seemed a little bit wasteful: 10,000 people vs 50 users For those more

Back in the horse-and-buggy days when I was cutting my OO eye teeth on Smalltalk, we had a LOT of conversations about the biggest problem dealing with a large and growing set of classes and methods in the Smalltalk image. It became clear that most, if not all, successful Smalltalk coders spent a lot of their time code-shopping, i.e., looking for a class or method that did something they

Hi ! I was talking to a seasider and he asked me if it was easy to do the following thing using rails : 1) ask a number to the user 2) ask a second number 3) give the addition of the two number and a link to be able to replay All these things have to be done in one controller and one action, there is no need for verification and other stuff. I tried but I''ve got some problems

Just tried the first AJAX example in the rails book (p.391-392, the ''word guessing'' thing), and the AJAX partial used seems to render as a full page. I''m not sure whether it''s a) a partial bug b) some interaction between ajax and partials c) a change since the book came out or d) pilot error I''ve checked the errata pages and it''s flagged up

Hi Railers, I have a scenario to figure out that I''ve never yet come to a good answer for, and I''m hoping some of you can shed some light. The owner of website I built a while back (in PHP) would like to extend the capabilities of the website to be fully CMS driven, with multiple language versions (French, Spanish etc.) available in future. At the moment, a few parts of

Hi Folks! I''m new in the forum and i have a doubt. The button back function with the Ajax on Rails? tks. -- Posted via http://www.ruby-forum.com/.

I am curious what you find is good and bad MVC design. Let''s use the find and find_by_sql methods as examples. Currently I have these spread out all over the place... View: here I have some find methods when I am for example populating a select list with choices in a form. Controller: here I have the simpler find methods. Model: here I have the more complicated find methods (usually
