  • Ruby generic filesystem libraries

    - by webdestroya
    I am looking for a "Virtual File System" type library for ruby. I want to be able to have a completely generic file system that I can easily switch between using Local files and using S3 or using FTP or something like that. (Identical to VFS for Java) Has anybody used any type of generic file system for ruby (I just need it to support local files and Amazon S3) Any pointers would be much appreciated.

  • Who's using Ruby on Rails in production?

    - by Jekke
    I've been kicking around Ruby and the rails framework and have been considering recommending to a client-of-a-client that they use it to rebuild their site, which is currently built in very bad ASP classic that will have to be rewritten from the ground up regardless of what technology is used. One thing I'm missing from my pitch is a list of major sites using Ruby-on-Rails. Are there any yet?

  • Parametrized get request in Ruby?

    - by Horace Loeb
    How do I make an HTTP GET request with parameters in Ruby? It's easy to do when you're POSTing: require 'net/http' require 'uri' HTTP.post_form URI.parse('http://www.example.com/search.cgi'), { "q" => "ruby", "max" => "50" } But I see now way of passing GET parameters as a hash using net/http.

  • Mavericks system Ruby and gem broken

    - by T1000
    When I tried to run ruby -v or gem -v (or any other command), I get: dyld: lazy symbol binding failed: Symbol not found: _ruby_run Referenced from: /usr/local/bin/ruby Expected in: /usr/lib/libruby.dylib dyld: Symbol not found: _ruby_run Referenced from: /usr/local/bin/ruby Expected in: /usr/lib/libruby.dylib This is after I ran rvm system to temporally switch to the system default Ruby. RVM is working fine, but I have a special need to install a gem to the system Ruby and I can't because of this problem. Does anyone know why? It seems to be some kind of link problem to Ruby, but I'm don't know how to solve this. I ran which ruby and it's at this point located in "/usr/local/bin/ruby". I checked the Ruby in "/usr/lib/" and it's pointing to my system Ruby: "../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/ruby" Any help would be appreciated.

  • Migrating Ruby Site from EngineYard to Heroku

    - by user410925
    As part of a larger project I've been tasked with migrating some existing Ruby on Rails sites (built with an old version of refinerycms 0.9.6.34, at least that's the version listed in the Gemfile included with the source). I don't normally work with Ruby so I'm at a bit of a loss. The previous developers simply handed over the latest git dump as well as a db dump. I'm working first with trying to get the site up working locally on an Ubuntu 11.10 local machine before pushing up to at test Heroku install. If it's possible to just push directly to Heroku with the files they gave, then I can try that, but it's my understanding I need to get everything working and then use Heroku's tools to deploy. The previous devs said they're using ruby 1.8.7 so in Ubuntu I've done the following: aptitude install ruby1.8 ruby1.8-dev ruby1.8-full aptitude install rubygems1.8 I've restored the database and in the config directory I've made changes to the database.yml to point to the restored database. When I try and run "bundle install" from the root of the extracted source dir I get: Invalid gemspec in [/var/lib/gems/1.8/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mime-types-1.18.gemspec]: invalid date format in specification: "2012-03-21 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec]: invalid date format in specification: "2012-03-19 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec]: invalid date format in specification: "2012-04-03 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mime-types-1.18.gemspec]: invalid date format in specification: "2012-03-21 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec]: invalid date format in specification: "2012-03-19 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec]: invalid date format in specification: "2012-04-03 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/mime-types-1.18.gemspec]: invalid date format in specification: "2012-03-21 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/sass-rails-3.2.5.gemspec]: invalid date format in specification: "2012-03-19 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/jquery-rails-2.0.2.gemspec]: invalid date format in specification: "2012-04-03 00:00:00.000000000Z" Fetching gem metadata from https://rubygems.org/.......

  • Ruby or Rails reporting tools?

    - by Anushank
    I am looking for a report generation tool in ruby or rails which allows the user to define a template, then fetch data into the created template. I have been looking through "The Ruby Box: reporting section." There are two reporting tools I have looked at: Thin Reports: It is really good. You can create your own report template with the template editor. Then you can produce PDF reports using thinreports gems. ODF Report: You can create a template ODF file using Open Office and MS Word, and you can use that template to generate the report. Both of these solutions lack the ability to draw charts. Does anyone know of similar reporting tools that can draw charts within a given report? I have tried the RTF Ruby Library. It works, but shares the limitation that it cannot draw charts and graphs. The minimum requirements are: Able to create customizable templates. (e.g. design layout, set font size, color, embed images etc.) Able to draw tables and charts. Template could be in Docx or excel or xml or any other common file format. Report output report must be in Docx or RTF format. Thanks

  • Rails app Hangs and Ruby uses 100% CPU

    - by tuzzolotron
    I have an apache2 server running Phusion Passenger. On this machine I have two virtual hosts setup each look like this (path's are different for the 2nd virtualhost...but other directives are the same) ServerName beta.mysite.us DocumentRoot "/var/www/beta/mysite/public" <Directory "/var/www/beta/mysite/public"> RewriteEngine on AllowOverride All Options FollowSymLinks </Directory> # http://www.modrails.com/documentation/Users guide.html PassengerAppRoot "/var/www/beta/mysite" RailsEnv development PassengerMaxPoolSize 6 PassengerDefaultUser mysite # PassengerHighPerformance does come at a trade off of lack of support for mod_rewrite PassengerHighPerformance off RailsSpawnMethod conservative RailsFrameworkSpawnerIdleTime 0 RailsAppSpawnerIdleTime 0 PassengerPoolIdleTime 300 ErrorLog "/var/log/httpd/mysite-beta-error_log" CustomLog "/var/log/httpd/mysite-beta-access_log" common Apache starts fine. I can go to one of the virtualhosts and it will load Rails and work. When I go to the second virtualhost, a ruby process spawns ("Rails: /var/www/mysite/current" according to ps awuxf) and uses 100% CPU. This process never exits. At this point neither virtualhost is responsive. If I kill the the offending ruby process, another ruby process replaces it and uses 100% cpu. If I kill these processes about 5-6 times, then both virtualhosts respond but they, are somehow, running the same Rails app?! I have another virtualhost on this machine that is not setup with phusion passenger..This one never exhibits any problems. Any help / ideas would be much appreciated!

  • when to choose ruby on rails over java [closed]

    - by Dany Y
    I have been working with Java EE for 6 years, and I have mostly used it even for simple applications like data-entry to database). I heard Ruby on Rails is superior to Java in this domain. What are the actual advantages of Ruby. and should I switch ? P.S : I know this is a subjective question, and the most probable answer is "depends on what you'll use it for", but this is exactly what I want to know when to use what. Thank you

  • 'Quickly': How can I use Ruby?

    - by ragu.pattabi
    Recently I came across Quickly. A very nice thing Ubuntu is doing in order to simplify creation of good looking applications that integrates well with Ubuntu desktop in every respect. While the demo was so cool and even motived me to learn Python, I am only familiar with Ruby. I would really love if there is a way to make Quickly do similar thing with Ruby. I read something about templates; but couldn't locate much details.

  • Email sent by ActionMailer is taking six hours to deliver mail.

    - by grg-n-sox
    So I have been asked to help maintain a website that uses Ruby on Rails. Now, let me just say I've been programming Ruby for awhile but I am still new to Rails. The first problem brought to my attention is how the activation email takes about six hours to arrive. It would be one thing if the email was not being sent due to errors but it is being send correctly, just slow. Also the server this is running on is also its own SMTP. I checked how the email was being formatted before calling the setup_email method and everything looks okay. I even dug into the ActionMailer lib and read through the files there and didn't see anything out of the ordinary. So what is most likely causing the email to take six hours to deliver?

  • _mask and Rails

    - by Eric Koslow
    So I am trying to get the cancan gem to work with my rails 3 app and I've hit a problem. I tried to copy the code that Ryan Bates (the creator of the gem) used in his screen cast, but I get an error saying that roles_mask is not a method. I figure that the _mask method was removed from Ruby/Rails at some point, and I'm now wondering what is the replacement. Here's the code in my user.rb model: named_scope :with_role, lambda { |role| {:conditions => "roles_mask & #{2**ROLES.index(role.to_s)} > 0 "} } ROLES = %w[admin student principal admissions] def roles=(roles) self.roles_mask = (roles & ROLES).map { |r| 2**ROLES.index(r) }.sum end def roles ROLES.reject { |r| ((roles_mask || 0) & 2**ROLES.index(r)).zero? } end def role? roles.include? role.to_s end def role_symbols roles.map(&:to_sym) end I'm using Rails 3 and Ruby 1.9.2dev Thank you

  • Integrate Jasper in Rails 3

    - by AndreDurao
    I'm trying to integrate a rails 3 app with jasper following this wiki: http://wiki.rubyonrails.org/rails/pages/HowtoIntegrateJasperReports But it seems that a lot of information isn't updated so it's been very hard to make it work by myself. I've also read a topic at ruby-forum: http://www.ruby-forum.com/topic/139453 with some details explained but still couldn't make it work. My first problem is related with the render_to_string method: When the controller method runs I receive a "Template is missing" error: this is the method: def report @customers = Customer.all send_doc(render_to_string(:template => report_customers_path, :layout => false), '/pdfs', 'report.jasper', "customers", 'pdf') end Although this seems simple I'm not understanding why is this happening. Doesn't render_to_string with layout = false suposed to get me the string result of that action? I also tried :action instead of :template, but it does the same. If anybody with some expertise with this integration could help... Thanks in advance, André
