ruby-1.9

I've setup Ruby 1.9.1 (p234) on a Ubuntu server. I'm trying to deploy a Rails app which vendors Rails 2.3-stable on Apache 2.2/Passenger 2.2.5. GET requests work fine, POST requests break immediately with the following log entry: Processing UsersController#new (for 80.203.77.44 at 2009-10-24 20:54:55) [GET] Parameters: {"controller"=>"users", "action"=>"new"} Rendering template within layouts/application Rendering users/new Completed in 23ms (View: 20, DB: 0) | 200 OK [ http://myapp/user/new] /!\ FAILSAFE /!\ 2009-10-24 20:55:01 +0200 Status: 500 Internal Server Error closed stream /usr/local

In the script I'm writing, I want find the length of a Fixnum in Ruby. I could do <num>.to_s.length , but is there any way to directly find the length of a Fixnum without converting it into a String? puts Math.log10(1234).to_i + 1 # => 4 You could add it to Fixnum like this: class Fixnum def num_digits Math.log10(self).to_i + 1 end end puts 1234.num_digits # => 4 Ruby 2.4 has an Integer#digits method, which return an Array containing the digits. num = 123456 num.digits # => [6, 5, 4, 3, 2, 1] num.digits.count # => 6 EDIT: To handle negative numbers (thanks @MatzFan), use the absolute value.

Recent versions of Ruby support the use of braces in globbing, if you use the File::FNM_EXTGLOB option From the 2.2.0 documentation File.fnmatch('c{at,ub}s', 'cats', File::FNM_EXTGLOB) #=> true # { } is supported on FNM_EXTGLOB However, the 1.9.3 documentation says it isn't supported in 1.9.3: File.fnmatch('c{at,ub}s', 'cats') #=> false # { } isn't supported (also, trying to use File::FNM_EXTGLOB gave a name error) Is there any way to glob using braces in Ruby 1.9.3, such as a third-party gem? The strings I want to match against are from S3, not a local file system, so I can't just ask the

In " Agile Web Development with Rails " (third edition) page 537 - 541 it has "Custom Form Builders" code as follows: class TaggedBuilder < ActionView::Helpers::FormBuilder # <p> # <label for="product_description">Description</label><br/> # <%= form.text_area 'description' %> #</p> def self.create_tagged_field(method_name) define_method(method_name) do |label, *args| @template.content_tag("p" , @template.content_tag("label" , label.to_s.humanize, :for => "#{@object_name}_#{label}") + "<br/>" + super) end end field_helpers.each do |name| create_tagged_field(name) end end This code doesn't work

I checked out the latest Ruby version, to play a bit with the latest changes. The first thing I tried to do was call a Ruby lambda/block/proc just like you'd do with a Python callable. a = lambda {|x| puts x} a.call(4) # works, and prints 4 a[4] # works and prints 4 a.(4) # same a(4) # undefined method 'a' for main:Object Why isn't the last call possible? Will it ever be? AFAIK it's because ruby doesn't let you define the () method for an object. The reason it doesn't let you define the () method is probably due to the fact that parentheses are optional in method calls. And for what it's worth

I'm using Ruby 1.9 and Rails 2.3.4 with Paperclip gem to save attachments. and I followed tutorial by adding the proper migration, adding (has_attached_file :video) to the model, making the form (multipart) and adding <%= f.file_field :video %> to it... When I try to upload a file I look in the log and I see: [paperclip] Saving attachments. But the file isn't really uploaded and the extra fields that have been added by paperclip are all NULLs!! The fact that it's not throwing any error making me confused where to start looking for possible issues. I'm using MAC OSX Leopard, is it possible that

New information This is what happens with rails console : Loading development environment (Rails 3.1.1) ruby-1.9.2-p290 :001 > RUBY_VERSION => "1.8.7" There's something really weird going on here - the prompt says 1.9.2 but RUBY_VERSION shows 1.8.7 . I'm using RVM, but I'm having problems with Rails on Ubuntu. $ which ruby /home/nick/.rvm/rubies/ruby-1.9.2-p290/bin/ruby $rvm list rvm rubies => ruby-1.9.2-p290 [ i686 ] But if I do gem env I get RubyGems Environment: - RUBYGEMS VERSION: 1.8.11 - RUBY VERSION: 1.8.7 (2011-06-30 patchlevel 352) [i686-linux] - INSTALLATION DIRECTORY: /home/nick/
