In my application a user working at a dropzone can manipulate transactions against customer accounts. Here''s my models: class Transaction < ActiveRecord::Base belongs_to :account end class Account < ActiveRecord::Base belongs_to :dropzone has_many :transactions end class Dropzone < ActiveRecord::Base has_many :transactions, :through => :accounts do def

Hi Gurus, I have a class, specified in models cart.rb, which doesn''t inherit from anything--it''s just a container class Cart ... I just discovered I can''t call number_to_currency in that class. Any idea how to "include" it in my code? I tried ActionView.number_to_currency without luck. I could kill a few lines of non-DRY regexp code in cart.rb if I could

So I have 2 models: Picture and Comment. Pictures have many Comments, but I''d like for users to be able to post Pictures in Comments, so Comments will have one Picture (possibly). This creates a kind of circular relationship it looks like, and the only way I could think of to implement this is with has_and_belongs_to_many. Am I right, or is there a better way to do this?

I have 3 methods: def add_to_cart # do some stuff redirect_to_index end def empty_cart # do some stuff redirect_to_index("your cart was emptied") end def redirect_to_index(msg = nil) flash[:notice] = msg if msg redirect_to :action => :index end How come the flash notice works if I''m setting msg = nil? For example, if I''m in empty_cart and pass

I''ve spent hours researching the subject and have tried many test sequences in IRB, and rails console but I''m just having trouble making headway into what is probably a very easy subject. I understand arrays with at least 4 other languages but with Ruby I haven''t found a mental connection with how I can assign variables to arrays.. Take for example: def

Hi -- Registration for RubyConf 2006 is still scheduled to open on August 2, in the early evening Pacific (US West Coast) time.

I''ve got a field in a database that contains a string of ids. I want to be able to remove an item from that list and save the list again. The only way I saw how to do this was to convert it to an array and back to a string again. The variable names are for an example. This code works, but I don''t think that it''s efficient. It''s all in my controller.

Would like to run PC Study Bible ver. 2 from BibleSoft on Linux. Research has led me to WINE. I am new to Linux, have Mandriva 2009 installed. I just DL'ed WINE for Mandriva 2009, and got it going. I tried to install PC Study bible from CD, no dice. I then copied the entire contents of PC Study Bible folder from a windows computer to flash drive and copied it to Linux computer. Still

PC Study Bible 4.2B and 4.2C have problems with the menus which are severely vertically compressed. Screenshot of problem: http://narnia.dnsalias.org/wine/PC%20Study%20Bible%20compressed%20menu%20flaw.png I am using Fedora Core 3. I tried all the winehq WINE RPMs between December and March. I think I used sidenet (not winetools) to install IE. IE and other programs work OK. The PC Study

Hi Folks, Is there a generally accepted Asterisk bible for current versions? I poked around the forums and there didn't seem to be a real consensus, and there are lots of options out there. I need something that focuses on Asterisk dialplans and config files, not a linux primer. I'm looking for dead-tree rather than online documentation. Thanks, Tim

I am very new to Linux but am enjoying it and liking it very much. I am up and running on debian sarge. Everything has been smooth except for one problem. I am invested in the Logos Bible Program and am trying to get it to run with wine. It gives me a textbox that says it must run on windows 98 ver or higher. I do not know what else to do. I am a minister and must use this program. What do

I run The Word Bible study program in Ubuntu 10.10 32 bit with ASUS K50IJ. The problem is, that the text shows black (the background is black, and the text is unreadable because of that), but only the longer verses. May be, that the video driver couses this problem? Intel GMA X4500M? Thanks, Attila [/img]

I''m trying to follow through with the Book Shelf app that''s in the ''Ruby on Rails Bible'' book and I''m at a point where I''m trying to install Ruby/Amazon. I downloaded the Ruby/Amazon and extracted it as instructed. Now I''m at the step where I need to drop into a Ruby console to verify the Ruby/Amazon installation. In the console I

I'm running PC Study Bible 5 through Wine. It works pretty fine, only need to install Gecko, which I did through winetricks, and change the windows version to Windows ME or earlier (98, 95, etc.). However, due to the large number of references used in the program (and the fact that ALL of them are loaded to memory on startup), the program gives me this warning:- "Exhausted Available

2 years later, and I thought to try this out again (been using e-sword happily). This time due to more error messages added (I think) to verison 1.3.5 I figured out I had to add a higher ulimt. Added "ngoonee hard nofile 32000" to /etc/security/limits.conf and restarted Installation didn't work on wow64, needed WINEARCH=win32 when actually creating ~/.wine before it would work

Hi everyone, I''m Italian and sorry for my english mistakes... I''m developing a web-site using rubyonrails. It''s REALLY COOL! But I''m obliged to re-use some javascript functions.
