In two weeks, Dave Thomas will be in Pasadena doing a three-day Rails workshop. I''m about to sign up for it. I figure three intense days with Dave and a few dozen other Rails developers will produce huge learning leaps for me. Then it occurred to me that it might be useful to ask the list if anyone has attended one of these workshops before and, if so, how valuable you found

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

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

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

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 =>

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

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

Hello, well, I searched list-archive, cran and the references, but found nothing. Thus: Does anybody around here know anything about Dempster-Shafer Theory, Evidence Theory or Hints in R? Has anybody stumbled about a package that I overlooked or implemented something in this area? I really would like to not implement a hint-model a second time. My apologies if I missed something obvious, but I

Dear all! I'd like to do multiple imputation of missing values with s-plus libraries that are provided by Shafer (http://www.stat.psu.edu/~jls/misoftwa.html). I wonder, whether these libraries are compatible or somehow convertible to R (because I don't have S-plus), so that I can use this functions using the R Program. I would be happy if you could tell me, -if it is possible to use

[ Wish there was a generic, active Linux "storage" mailing list out there -- something other than the kernel lists I mean ] To frame the discussion, we use VMware ESX (vSphere) quite a bit with NFS datastores. Often times with NetApp, but lately, more often with Solaris 10 + ZFS + SSD's for ZIL (intent log or write cache). The ZIL lets us use synchronous writes (safer) without

I am using the RGL library in scripted (non-interactive) mode, but wish to give the data analyst an opportunity to exam the 3D plots. The "data analysts" understand the data, but not R. My intent is to provide simple Windows (XP) batch files that call R and automatically pass scripts to it, and thus permit the analyst to easily access graphics without having to cut and paste commands

Hi, I have had a quick search to see whether this question has been asked/answered before but haven't found anything directly related to it. Basically, I am wondering if I can run the packages, developed by Shafer for S-Plus, that allow multiple imputation of missing data - NORM, CAT, MIX, and PAN. If not, does anyone know if someone has done the modification that would make these packages

I now this may be a touchy subject, but I'll preface by saying that I'm trying to get away from Real Networks. Now that video is becoming a reality with Icecast, I want to make a slow transition from using RealServer to using Icecast. I have 20GBs of video content in Real format so I need to keep using the RealServer, but I want to start running the live audio stream with Icecast. Has

I have a table with some data structured something like this: book ---- title (varchar) pages (int) completed_on (date) While I can find the shortest book completed in each year with something like this: select min( pages ), year from book group by year I would also like to get the title of the shortest book in each year. Is there any way to do this by modifying the previous query to pull

Hi All, As per subject line looking for info. Have client looking to setup about 10 users running AutoCAD with all CAD files being stored and edited on local Linux/Samba server. Not much luck in finding anything of detail from numerous Google searches. File locking is of course an issue with multiple users. Client workstations running WinXP Pro and using a mix of AutoCAD versions 2000, 2003 and
