I have installed Ruby and Rails on my Intel iMac according to the instructions provided by Hivelogic. Everything works perfectly. I have noticed that if I close Terminal and later come back and open it, It seems like the paths set in bash_login are lost. If I open bash_login the paths are still there however if i do ruby -v it says I am running 1.8.2 (mac default) when I have installed 1.8.4.

In my rjs template I''m using the following line. page.visual_effect :slideUp, ''comment_error_details'', :duration => 0.5 It works fine if I have created the div with the id="comment_error_details", but if I haven''t created the error yet then my whole rjs template fails. How can I check to see if an element has been created? I could then put

Hi all, lately I''ve been working with ROR on a MAC OSX tiger at work, however I have one huge problem with seems to be the root of all my problems whenever I use terminal or iTerm to start workign with ROR. Every single time I open a new terminal window or close one and open a new one, I have to reapply my path from .bash_login for Ruby and MySql, and than I have to install the

Here''s my crazy question of the day. Has anybody played around with using Rails to create Mac OS X Dashboard Widgets? Or is that just sick and wrong? Giles

I would like to define some constants that I can use across models and views and I cannot figure out how to do that. Googling hasn''t turned up anything useful and I''m looking at the PickAxe book, and I get the impression that a constant must belong to a class. If I just want a constant like... CompanyPhoneNo = "(602) 999-9999" and be able to use it in any view

Anyone know (or know where to point me to) to figure out how to force Rails into development mode? I''d like to not have to kill dispatch.fcgi everytime I make a change. My site is not live and I''m just doing development and testing right now. Thanks. -- Posted via http://www.ruby-forum.com/.

When I explain RoR to someone I don''t have a convincing argument that explains why everything is so automatic and transparent, but relationships have to be encoded by hand in models. That shows I don''t understand well that part of AR. There''s the argument that says that not all databases offer metadata about foreign keys, but the natural question then is that,

Hello, How do I prevent previously submitted form data from being reinserted into the database when the user presses the browser''s Refresh button? On Aughey''s advice in #irc I tried using `redirect_to'' a new `:action'' but this approach doesn''t seems to work. Any idea what might be wrong or how to tackle this problem? Thanks for your help. P.S.- I

using the below: <%= select(''project'', ''project_type_id'', @project_types.collect {|x| [x.name,x.id]}, {:include_blank => true}) %> but i''d like that first option to have something like "select project type" with an empty value?

I have a form that I want to do a few things. -do an Effect.SlideOut on a div -replace the text in a div with different text -update the database and add a new div later in the document. How do call all of these (there is only one :complete or :update) Thanks in advance. -- Posted via http://www.ruby-forum.com/.

There''s an excellent write up by Stefan Kaes that''s specific to components and how they can slow down a Rails apps, but also offers an excellent introduction to using Ruby profiling tools to identify and remove bottlenecks at: <http://railsexpress.de/blog/articles/2005/11/18/components-may-not- be-evil-but-they-sure-can-be-slow> -- Jason Perkins jperkins@sneer.org

Hello, If your operation depends on FreeBSD you should be aware there is currently a funding request by the FreeBSD security officer. I''m relaying this information because I know FreeBSD is an important platform for Rails and I hope those of you who do depend on FreeBSD will be willing to put some money forward for this valuable work to continue. You can read about the request

I sure hope so: http://duckdown.blogspot.com/2006/03/additional-thoughts-on-why-ruby-isnt.html Seems like it''s getting genuine rebuttals, though. It''s actually kind of amusing.

I have a class Player, and a class Game. Game has two HABTM relationships to the Player table through seperate relationship tables. class Game < ActiveRecord::Base has_and_belongs_to_many :players, :uniq => true has_and_belongs_to_many :victors, :class_name => ''Player'', :uniq => true end When I add Player A to players, and Player B to victors, and save the

I''m on Mac OSX and I''m about to rip my hair out over how hard it is to install rails. I''ve installed rubygems and am typing "ruby setup.rb" in the command line and get "No such file or directory." I''ve never had to use command lines before so this is alien to me. Can''t they just make installation GUI-based for non-geeks like

Here is a problem scenario. I want to enable a backend pass at -O2 or above. if (TM->getOptLevel() >= CodeGenOpt::Default) addPass(&xxxxx); This pass will be run at -O1 too since clang is creating the TargetMachine with CodeGenOpt::Default for -O1. --Sumanth G -----Original Message----- From: mehdi.amini at apple.com [mailto:mehdi.amini at apple.com] Sent: Friday, January 6, 2017

Hi, AFAIK, the tools "symbolizer, objdump and nm" need a demangler. I see there is libcxxabi which provides the demangle library. But there is no support to build libcxxabi on windows with MSVC. This left a huge void and my symbolizer cannot work on Windows if built with MSVC. Instead of mucking around OS dependencies, why shouldn't we have a demangle library in LLVM.

Hi, I see there is an inconsistency in LLVM libc calls. For a modulo (reminder) operation, clang -target arm-none-linux-gnueabi generates "__modsi3". clang -target arm-none-eabi generates "__aeabi_idivmod" clang -target arm-linux-androideabi generates "__modsi3" Android bionic libc doesn't provide a __modsi3, instead it provides
