  - by Nick Gorbikoff

  Hello I develop on a Windows machine but deploy to Debian. Trying to use hpricot with Rails 3 app. I can get the gem to install using : gem install hpricot --platform=mswin32 But when I do this in the bundle file - it keeps throwing an error (I think it's trying to install the wrong version of hpricot (not windows specific) group :production do gem "hpricot", "0.8.3" end group :development, :test do gem "hpricot", "0.8.3", :platforms => [:mswin, :mingw] end This is from another question here on stackoverflow - but it's not working for me.

• Ruby: how to step through ruby code

  - by user1647484

  I'm trying to learn how to step through Ruby code (written by more experienced programmers) in order to improve my knowledge of Ruby. Problem is that I don't really know how to do it well. Googling the topic brought me to an about.com page on Ruby; I thought a higher quality more comprehensive answer should belong on StackOverflow, so if anyone can write an answer (with an example) for it, showing how a beginner can step through code to learn as much as possible about it, it'd be much appreciated.

• marshal data too short!!!

  - by Nitin Garg

  My application requires to keep large data objects in session. There are like 3-4 data objects each created by parsing a csv containing 150 X 20 cells having strings of 3-4 characters. My application shows this error- "marshal data too short". I tried this- Deleting the old session table. Deleting the old migration for session table. Creating a new migration using rake db: sessions:create. editing the migration manually, changing "text: data" to "longtext: data". running the migration using rake db: migrate. now when i open my application, i see this page- link text please someone help me, this is getting on my nerves!! other details of application-- In view "index.html.erb"- There is a link that makes ajax call to an action in controller, that action parses large csv file and makes an object out of it. this object is stored in session.

• Sinatra and XML POST request

  - by user292815

  I don't know is it my mistake or no. So i have that code: <code> post '/singin/get_token' do content_type :xml puts request.body.read puts xmlRequest xmlRequest = REXML::Document.new(request.body.read) ... </code> And when i post something like that: <code> <?xml version="1.0" encoding="utf-16"?><request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><username>adsfasdf</username></request> </code> I receive that in my console: <code> 127.0.0.1 - - [12/Mar/2010 21:18:20] "POST /singin/get_token HTTP/1.1"

• Rails 2.3.5 and oauth-plugin

  I started a rails application from scratch, using Rails 2.3.5, and installed oauth-plugin. The installation was done by running script/plugin install git://github.com/pelle/oauth-plugin.git.

• rake migration aborted: could not find table 'roles'

  - by user464180

  I just inherited code that I'm attempting to run the migrations for but I keep getting a rake aborted error. I've come across others that have what appears to be similar issues, but most involved Heroku and I'm trying to run this locally (to start.) I've tried troubleshooting using both PostgreSQL and SQLite, and both produce the same issue. The table "roles" referenced is the second migration called, so I'm having a hard time figuring out what is causing it to not get built. Any and all assistance is greatly appreciated. Thanks in advance. Here's the roles migration: class CreateRoles < ActiveRecord::Migration def change create_table :roles do |t| t.string :name t.timestamps end end end Here is the trace for SQLite: ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment rake aborted!

  Hi all, My rails server seems to break after installing the facebooker plugin. Any suggestions on fixing this would be great. I'm using rails 3.0.0.beta and facebooker. Here are the steps and the error that I'm seeing: $ rails -v Rails 3.0.0.beta $ rails break; cd break $ ./script/rails plugin install git://github.com/mmangino/facebooker.git $ vim Rakefile #and add "require 'tasks/facebooker'" $ ./script/rails server => Booting WEBrick => Rails 3.0.0.beta application starting in development on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server Exiting /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:456:in `load_missing_constant': uninitialized constant ActiveSupport::CoreExtensions (NameError) from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:91:in `const_missing' from /path/break/vendor/plugins/facebooker/lib/facebooker/adapters/adapter_base.rb:6 from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:537:in `new_constants_in' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /path/break/vendor/plugins/facebooker/lib/facebooker.rb:252 from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:537:in `new_constants_in' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /path/break/vendor/plugins/facebooker/rails/../init.rb:5 from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:537:in `new_constants_in' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /path/break/vendor/plugins/facebooker/rails/init.rb:1 from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/plugin.rb:49 from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/initializable.rb:25:in `instance_exec' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/initializable.rb:25:in `run' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/initializable.rb:55:in `run_initializers' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/initializable.rb:54:in `each' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/initializable.rb:54:in `run_initializers' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/application.rb:71:in `initialize!' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/application.rb:41:in `send' from /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/application.rb:41:in `method_missing' from /path/break/config/environment.rb:5 from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:537:in `new_constants_in' from /Library/Ruby/Gems/1.8/gems/activesupport-3.0.0.beta/lib/active_support/dependencies.rb:167:in `require' from config.ru:3 from /Library/Ruby/Gems/1.8/gems/rack-1.1.0/lib/rack/builder.rb:46:in `instance_eval' from /Library/Ruby/Gems/1.8/gems/rack-1.1.0/lib/rack/builder.rb:46:in `initialize' from config.ru:1:in `new' from config.ru:1

• Advice for someone moving from Windows / Coldfusion / Java to Linux / Ruby / Rails

  - by Ciaran Archer

  Hi all I am thinking of undertaking a serious career move. Currently I work day to day with ColdFusion 9+, and some Java in a Windows environment. My background is Java/JSP etc prior to ColdFusion. I'm considering a move towards Ruby / Rails on Linux as I think it would be a real challenge, keep things fresh and would stand me in good stead for the next few years. There are also more jobs in this area. I would consider myself an experienced web professional. I do TDD and I understand good OO design concepts. I have worked for the past few years on a busy transactional gaming website with all the security and performance challenges that entails. I have also contributed to an open source ColdFusion project recently and I am a active member of the CF community on StackOverflow . In order to maintain my current remuneration (!) etc. I would like to get up to speed on Ruby / Rails and Linux before I go job hunting. The idea is that I can demonstrate enough proficiency in these new skills and combined with my other language / programming / architectural and performance experience I have I'll be a good candidate. I am building a personal website in Rails 3.0 on Ubuntu which I hope will expose me to lots of Rails/Ruby and I am reading a few books. What else can I do? Has anyone made this type of move, and if so would they have any tips apart from what I've mentioned? Is there any areas around Rails/Ruby/Linux that I have to get up to speed with? Any and all tips are appreciated.

• Ruby but not Rails on my Resume

  - by Ken Bloom

  I have listed Ruby as a skill on my resume becuase I've been programming in Ruby for 5 years while I work on my Ph.D. thesis. I've mostly been using it to implement natural language processing algorithms. I'm starting to look for a job, and I posted my resume to a few sites (as an extra bonus when applying to certain on-target jobs). Now I get recruiters calling me to offer me Ruby on Rails jobs. The problem is that I've never learned Rails. It was never relevant to what I'm doing for my Ph.D. How do you recommend handling this situation to avoid wasting my time and theirs? (And learning Rails probably isn't an option until I finish my thesis.) Can my resume be adjusted to make this clearer? Should it be adjusted? Should I just politely tell them on the phone that I don't know Rails? By the way, the relevant part of my resume simply says: Skills: Programming Languages: C, C++, Java, Scala, Ruby, LaTeX Databases: MySQL, XML, XPath and lists a few other skill areas that couldn't possibly be confused with a Rails developer.

• "Malformed version number string mingw32" when starting rails

  - by Freewind

  My os: windows xp, ruby: 1.8.7, rails: 2.3.5 Everything was fine, but I just installed a "gcc-4.4.0-mingw32-bin", and run gem install rdiscount, then my rails can't start. Now when I run ruby script/server, or rake gems:install, the following error will occur: rake aborted!

• Exception with RubyAMF and Ruby 1.9 although code works

  I'm getting an exception with RubyAMF using Ruby 1.9 and Rails 2.3.5. Although code afterward executes normally I'm not very comfortable with seeing such exception in the log file.

  Did you know you can now develop services and applications in Python or Ruby with Oracle Tuxedo? The Tuxedo team have a blog post about it at Python and Ruby in Tuxedo. I used to think of Tuxedo as a Transaction Processing Monitor but it has evolved into much more.

What are the best RSS feeds? What are the best books? Blogs? Videos? Any information you can share would be great!

• I'm a student learning C++ and I've recently found out about Ruby. Would learning (some of) Ruby help me with C++ or would it just confuse me?

  - by Von32

  Hi! As the title says, I'm a student that will be starting my second year of C++ very soon. I've discovered Ruby, however. While I've heard much buzz about the language before, I've disregarded it because I always thought it wasn't something that would be useful. However, I've found a number of FANTASTIC tutorials on ruby and am interested in learning it (probably because it seems so straightforward). Would playing around with ruby be a good or bad idea? I understand that there's not such thing as bad knowledge, but I'm afraid that Ruby will only confuse me when dealing with C++. How different from C++ is it? I've read it's based on C in some way, but my google-fu seems to be horrible today. How useful is Ruby in the real world? I'm not specifically asking about jobs- I'm more interested in what sort of applications may come from this language. Any specific examples worth looking at? Going back to Question two- I've read some posts on here that Ruby and C++ can hold hands once in a while. How flexible is this relationship? Is it rarely that this would work? Thank you Very much for your time! EDIT: This has to be the one community on the internet that doesn't suck. Why have I never posted before? You guys are awesome!
