  • no such file to load -- for several gems unpacked in a Rails 2.3.8 app

    - by vincentp
    Hi, I unpacked several gems into the /vendor/gems folder, and I get the same error message for 5 of these gems when I try to start my Rails application. The date-performance one as an example : no such file to load -- date_performance.so /opt/ruby-enterprise-1.8.7-20090928/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' /opt/ruby-enterprise-1.8.7-20090928/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' /opt/ruby-enterprise-1.8.7-20090928/lib/ruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' /opt/ruby-enterprise-1.8.7-20090928/lib/ruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:521:in `new_constants_in' /opt/ruby-enterprise-1.8.7-20090928/lib/ruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:156:in `require' /path_to_my_app/vendor/gems/date-performance-0.4.8/lib/date/performance.rb:34 ... Here is the line 34 : require 'date_performance.so' I'm including the gem using the following code : config.gem "date-performance", :lib => "date/performance" The '.so' file is under /path_to_my_app/vendor/gems/date-performance-0.4.8/lib/ Any idea on why things were working while the gems were not unpacked? Do you have any idea about this behavior? I'm using : Rails 2.3.8 REE 1.8.7 gem 1.3.6 Mac OS X Thanks! Vincent

  • OpenSSL support for Ruby: "Cipher is not a module (TypeError)"

    - by smotchkkiss
    The Problem Our systems admin needed to upgrade the packages on our CentOS 5.4 dev server to match the packages on our production server. The upgrade affected ruby and/or openssl. We run a Ruby on Rails issue tracking system called Redmine that is deployed with Passenger on Apache. Everything worked before the server update, but when trying to access the ticket system now, I get the following error: Error message: Cipher is not a module Exception class: TypeError Application root: /home/dev/rails/redmine-0.8.7 I've been trying so hard to fix this problem but I can't seem to beat it. I have tried following this guide: http://iamclovin.posterous.com/how-to-solve-the-cipher-is-not-a-module-error When I try require 'openssl' in IRB, I do see a true return value. However, I'm still seeing the Cipher.rb is not a module TypeError when accessing the ticket system. Possibly (probably) related: I've tried updating Passenger, but when I try passenger-install-apache2-module I see: Checking for required software... * GNU C++ compiler... found at /usr/bin/g++ * Ruby development headers... found * OpenSSL support for Ruby... /usr/lib/ruby/1.8/openssl/cipher.rb:22: Cipher is not a module (TypeError) Any help?

  • Installing Ruby on Rails on Ubuntu 10.04: A Living Nightmare

    - by emptyset
    Update #3: Starting over from scratch, shortened this post, decided to re-install a clean copy of Ubuntu 10.04 on a VM and go through the walk-through again. So, all the steps go without a hitch. As root: root@ubuntu:~/rubygems-1.3.7# ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux] root@ubuntu:~/rubygems-1.3.7# gem -v 1.3.7 root@ubuntu:~/rubygems-1.3.7# rails -v Rails 2.3.8 Now, as myself (in a separate term): emptyset@ubuntu:~$ ruby -v ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux] emptyset@ubuntu:~$ gem -v /usr/local/lib/site_ruby/1.8/rubygems.rb:10:in `require': no such file to load -- rubygems/defaults (LoadError) from /usr/local/lib/site_ruby/1.8/rubygems.rb:10 from /usr/local/bin/gem:8:in `require' from /usr/local/bin/gem:8 emptyset@ubuntu:~$ rails -v bash: /usr/bin/rails: Permission denied So, this appears to be a permissions issue, but I don't understand why. Specifically, if I have to start making things go+rx all over the place, I really need to understand which specific files need the permissions change.

  • Cannot find Ruby on Rails installed

    - by James
    I've managed to install Ruby and the gems install (rvm?) but now I'm stuck actually installing Ruby on Rails. Every time I execute, gem install rails Terminal says that it's fetching each file and that it successfully installed it: 1 gem installed However when I then run the rails command, I'm told that it's not installed and to run the gem install rails command again. I've attempted to install with sudo but the same thing happens. I've restarted after an install and that's not worked. Ideas?

  • combining ruby and C++

    - by Shingetsu
    Hello /* programmers */ (I usually hang in SO) I've been discussing a conceptual project with a friend of mine and the the most effective way we've seen of doing it is writing the engine in C++ while the logic would be done in Ruby. However, we would need data to be passed around often, for example: Engine reports that A happened, that gets triggered in a proc array (event "A" is passed but proc doesnt use it) Ruby decides that we need to wait for B to happen Ruby adds a proc to an array. The array of procs is iterated during each cycle in the C++ engine C++ engine reports that B happened and passes "event B (should be a ruby object) Ruby receives event B and decides what to do next I don't work with multiple languages often, and was wondering if it's possible to implement things in this way. I know that there's the ruby VALUE in C++, but would like to know the standard way of combining the two. (of course I know ruby follows the perl "more than 1 way to do it", but there's often a standardized way)

  • Rails 3.0.3 and Polyglot Gem problem

    - by user557417
    Hello all. I hope you can help me. I had a rails app running locally, and also uploaded and running on Heroku. All was well. Last week, I started work again and ran into a snag. At the beginning of my day, I opened up Terminal and ran 'rails s' to start the local server. I received this error: doug-naegeles-macbook-pro-17:elig_check dougnaegele$ rails s /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/resolver.rb:129:in resolve': Could not find gem 'polyglot', required by 'rails (= 3.0.3)', in any of the sources (Bundler::VersionConflict) from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/resolver.rb:127:incatch' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/resolver.rb:127:in resolve' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/definition.rb:151:inresolve' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/definition.rb:90:in specs' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/definition.rb:135:inspecs_for' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/definition.rb:124:in requested_specs' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/environment.rb:23:inrequested_specs' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler/runtime.rb:11:in setup' from /Library/Ruby/Gems/1.8/gems/bundler-1.0.7/lib/bundler.rb:100:insetup' from /Users/dougnaegele/Sites/elig_check/config/boot.rb:8 from script/rails:5:in `require' from script/rails:5 When I run 'gem list'..i can see Polyglot listed: doug-naegeles-macbook-pro-17:elig_check dougnaegele$ gem list * LOCAL GEMS * abstract (1.0.0) actionmailer (3.0.3, 2.3.5, 2.2.2, 1.3.6) actionpack (3.0.3, 2.3.5, 2.2.2, 1.13.6) actionwebservice (1.2.6) activemodel (3.0.3) activerecord (3.0.3, 2.3.5, 2.2.2, 1.15.6) activeresource (3.0.3, 2.3.5, 2.2.2) activesupport (3.0.3, 2.3.5, 2.2.2, 1.4.4) acts_as_ferret (0.5.2, 0.4.3) arel (2.0.6, 2.0.4) authlogic (2.1.6) blythedunham-sms_on_rails (0.1.0) builder (3.0.0, 2.1.2) bundler (1.0.7) capistrano (2.5.19, 2.5.2) cgi_multipart_eof_fix (2.5.0) color (1.4.1) configuration (1.2.0) crack (0.1.8) daemons (1.1.0, 1.0.10) derailed-ziya (2.1.5) dnssd (1.4, 0.6.0) erubis (2.6.6) fastthread (1.0.7, 1.0.1) fcgi (0.8.8, 0.8.7) ferret (0.11.6) gem_plugin (0.2.3) googlecharts (1.6.0) heroku (1.14.10, 1.14.3) highline (1.6.1, 1.5.0) hpricot (0.8.3, 0.6.164) httparty (0.6.1) i18n (0.5.0, 0.4.2) jk-ferret (0.11.8.2) json_pure (1.4.6) launchy (0.3.7) libxml-ruby (1.1.4, 1.1.2) little-plugger (1.1.2) logging (1.4.3) mail (2.2.12, 2.2.10) mattetti-googlecharts (1.4.0) mime-types (1.16) mongrel (1.1.5) mysql (2.8.1) needle (1.3.0) net-scp (1.0.4, 1.0.1) net-sftp (2.0.5, 2.0.1, 1.1.1) net-ssh (2.0.23, 2.0.4, 1.1.4) net-ssh-gateway (1.0.1, 1.0.0) nifty-generators (0.4.2) polyglot (0.3.1) rack (1.2.1, 1.0.1) rack-mount (0.6.13) rack-test (0.5.6) rails (3.0.3, 2.3.5, 2.2.2, 1.2.6) railties (3.0.3) rake (0.8.7, 0.8.3) RedCloth (4.2.3, 4.1.1) rest-client (1.6.1) ruby-openid (2.1.8, 2.1.2) ruby-yadis (0.3.4) rubygems-update (1.3.7, 1.3.6) rubynode (0.1.5) sequel (3.18.0, 3.17.0) sinatra (1.1.0, 1.0) sqlite3-ruby (1.3.2, 1.2.5, 1.2.4) static_record_cache (0.2.0) taps (0.3.14) termios (0.9.4) thor (0.14.6) tilt (1.1) treetop (1.4.9) twilio (2.9.0) twiliolib (2.0.7) tzinfo (0.3.23) xmpp4r (0.5, 0.4) When I run 'gem sources' I get this: doug-naegeles-macbook-pro-17:elig_check dougnaegele$ gem sources * CURRENT SOURCES * rubygems.org/ gems.github.com gems.github.com gems.github.com/ gems.github.com gems.rubyforge.org Which looks right -- that's where Polyglot lives.

  • Run Rails 3 app on a Rails 2 server/machine?

    - by chucknelson
    I'm trying to run a Rail 3 (3.0.10) app on a shared joyent smartmachine server (I don't have root access) which has Rails 2 (2.3.11) installed , and I'm not sure what to do after I freeze my Rails 3 app with bundle install --deployment. It seems like with the Rails 3 and bundler gems not being installed on the server locally, my app isn't even recognizing the local version of Rails I have frozen with my app. Has anyone gotten this to work, or have any advice? The server runs Apache, and I think I can get lighttpd installed too - but I'd rather stay with Apache if I can. Also, if it matters, Passenger is not an installed gem either...and I'm not sure I can freeze that with my app. Update 11/30/2011 12:30 PM EST Bundler is not installed on this server, either. Not sure if having that would enable the new Rails 3 "freeze" (bundle --deployment) to work or not...

  • package issue with ubuntu 10.10 and passenger requirements

    - by user368937
    I'm trying to get Passenger working with Ubuntu 10.10 and I'm running into a problem. It seems that the passenger installer is not recognizing the virtual package. I'm getting this error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... And then it says, run this: * To install OpenSSL support for Ruby: Please run apt-get install libopenssl-ruby as root. When I run the above command, it refers to the libruby package: sudo apt-get install libopenssl-ruby Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'libruby' instead of 'libopenssl-ruby' libruby is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 43 not upgraded. When I look at the details for libruby, it says it provides libopenssl-ruby: Code: Provides: libbigdecimal-ruby, libcurses-ruby, libdbm-ruby, libdl-ruby, libdrb-ruby, liberb-ruby, libgdbm-ruby, libiconv-ruby, libopenssl-ruby, libpty-ruby, libracc-runtime-ruby, libreadline-ruby, librexml-ruby, libsdbm-ruby, libstrscan-ruby, libsyslog-ruby, libtest-unit-ruby, libwebrick-ruby, libxmlrpc-ruby, libyaml-ruby, libzlib-ruby And when I rerun the passenger installer, it gives the same error: Code: passenger-install-apache2-module ... * OpenSSL support for Ruby... not found ... Let me know if you need more info. How do I fix this?

  • How to extend an 'unloadable' Rails plugin?

    - by Vitaly Kushner
    I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back.

And with that information in my model, I can in my list view use this code <%=h @list.wishes.count % well now I have made an controller called statusboard.. And in that' I have 3 functions.. Or how to say it.. but it is Index, loggedin, loggedout.. And .. In loggedin and in the file #app/views/statusboard/loggedin.html.erb i want to display this.. Howdy {Username}, you have made {count lists} lists, and {count wishes} wishes here is that i figured i should write in my file.. Howdy {Username}, you have made <%=h @user.list.count % lists, and <%=h @user.wishes.count % wishes my list model is like this = class List < ActiveRecord::Base   attr_accessible :user_id, :name, :description   belongs_to :users   has_many :wishes end and my wish model is like this = class Wish < ActiveRecord::Base   attr_accessible :list_id, :name, :price, :link, :rating, :comment   belongs_to :list end and last my user model is like this = class User < ActiveRecord::Base   # Include default devise modules.

  • Rails validation "failing when succeeding"

    - by Fredrik
    I have this in my user.rb: attr_accessor :old_password def validate unless password.nil? errors.add_to_base("Old password entered incorrect") unless self.valid_password? old_password end end I have old_password as a a virtual attribute that has to be validated as matching with the current before updating to a new password. My problem is that upon correct entering ( password == password confirmation and self.valid_password? old_password ) an error will yield and pass me back to the form. The strange part is that the data will actually be updated in the database, and it will not on wrong input; although it will yield the very same error ("Old password entered incorrect"). What on earth am I doing wrong?

  • Where to put reusable methods for access by controllers in rails

    - by 99miles
    I have several methods I call from my controllers that feel like they should be pulled out and put into a reusable class, outside of the controller. Where do people usually put this stuff? I know I can put them into my ApplicationController, but that doesn't seem to be a great solution if I think I can use these methods later in other applications. Also, I have a bunch of utility methods in my controllers that likely won't be used in other controllers, or in the future at all, but I feel like they just bloat my controller a bit. Do people usually move these out someplace for cleanliness or just end up with a huge controller? I'm coming from Java and Actionscript where I'd just create new util classes for this stuff.

  • Rails 3, changing a specific value in a row

    - by Elliot
    Hey Guys, This question seems ridiculously easy, but I seem to be stuck. Lets say we have a table "Books" Each Book, has a name, description, and a status. Lets say I want to create link in the show view, that when clicked, solely changes the status (to "read") for example. So far, I've tried adding a block in the controller, that says: def read @book = Book.find(params[:id]) @book.status = "Read" @book.update_attributes(params[:book]) respond_to do |format| format.html { redirect_to :back} format.xml { render :xml => @book } end end Then I've added a link to the view that is like: <%= link_to "Read", read_book_path(@book), :method = :put % This isn't working at all. I have added it to my routes, but it doesn't seem to matter. Any help would be great! Thanks! -Elliot EDIT: Forgot to add I'm getting a NoMethodError: undefined method `read_book_path'

  • Creating thousands of records in Rails

    - by willCosgrove
    Let me set the stage: My application deals with gift cards. When we create cards they have to have a unique string that the user can use to redeem it with. So when someone orders our gift cards, like a retailer, we need to make a lot of new card objects and store them in the DB. With that in mind, I'm trying to see how quickly I can have my application generate 100,000 Cards. Database expert, I am not, so I need someone to explain this little phenomena: When I create 1000 Cards, it takes 5 seconds. When I create 100,000 cards it should take 500 seconds right? Now I know what you're wanting to see, the card creation method I'm using, because the first assumption would be that it's getting slower because it's checking the uniqueness of a bunch of cards, more as it goes along. But I can show you my rake task desc "Creates cards for a retailer" task :order_cards, [:number_of_cards, :value, :retailer_name] => :environment do |t, args| t = Time.now puts "Searching for retailer" @retailer = Retailer.find_by_name(args[:retailer_name]) puts "Retailer found" puts "Generating codes" value = args[:value].to_i number_of_cards = args[:number_of_cards].to_i codes = [] top_off_codes(codes, number_of_cards) while codes != codes.uniq codes.uniq! top_off_codes(codes, number_of_cards) end stored_codes = Card.all.collect do |c| c.code end while codes != (codes - stored_codes) codes -= stored_codes top_off_codes(codes, number_of_cards) end puts "Codes are unique and generated" puts "Creating bundle" @bundle = @retailer.bundles.create!(:value => value) puts "Bundle created" puts "Creating cards" @bundle.transaction do codes.each do |code| @bundle.cards.create!(:code => code) end end puts "Cards generated in #{Time.now - t}s" end def top_off_codes(codes, intended_number) (intended_number - codes.size).times do codes << ReadableRandom.get(CODE_LENGTH) end end I'm using a gem called readable_random for the unique code. So if you read through all of that code, you'll see that it does all of it's uniqueness testing before it ever starts creating cards. It also writes status updates to the screen while it's running, and it always sits for a while at creating. Meanwhile it flies through the uniqueness tests. So my question to the stackoverflow community is: Why is my database slowing down as I add more cards? Why is this not a linear function in regards to time per card? I'm sure the answer is simple and I'm just a moron who knows nothing about data storage. And if anyone has any suggestions, how would you optimize this method, and how fast do you think you could get it to create 100,000 cards? (When I plotted out my times on a graph and did a quick curve fit to get my line formula, I calculated how long it would take to create 100,000 cards with my current code and it says 5.5 hours. That maybe completely wrong, I'm not sure. But if it stays on the line I curve fitted, it would be right around there.)

  • getting rid of ruby gems that won't die

    - by holden
    I've got a few ruby gems that won't go away. I think it has to do with when I installed them. Occasionally I have forgotten to use "sudo" before doing a gem install, which results in a write error and from what I can gather puts a copy of the gem in my user directory instead of somewhere it can run. But gem uninstall doesn't work. It continually shows up in 'gem list' but can't uninstall it from either gem uninstall, or sudo gem uninstall. I tried directly deleting one gem after finding the path in my 'gem environment', but that still left the gem on the list. Also is it possible just to remove all gems and start from scratch? These are driving me nuts. I'm running OS X. Thanks,

  • Rails 3: Parsing XML

    - by gjb
    I have a simple XML document in the following format: <?xml version="1.0" encoding="utf-8"?> <object> <strField>Foo</strField> <intField>1</intField> <dateField>2010-11-03</dateField> <boolField>true</boolField> <nilField></nilField> </object> I would like to parse this into a Hash to be passed to Model.create: {:object => { :strField => 'Foo', :intField => 1, :dateField => Date.today, :boolField => true, :nilField => nil }} Sadly there are no "type" attributes in the XML, so using Hash.from_xml just parses each field as a string. What I am looking for is some sort of field type auto detection. I have also looked at Nokogiri, but that can't output as a Hash. What is the simplest and most efficient way to achieve this? Many thanks.

  • Rails: unable to set any attribute of child model

    - by Bryan Roth
    I'm having a problem instantiating a ListItem object with specified attributes. For some reason all attributes are set to nil even if I specify values. However, if I specify attributes for a List, they retain their values. Attributes for a List retain their values: >> list = List.new(:id => 20, :name => "Test List") => #<List id: 20, name: "Test List"> Attributes for a ListItem don't retain their values: >> list_item = ListItem.new(:id => 17, :list_id => 20, :name => "Test Item") => #<ListItem id: nil, list_id: nil, name: nil> UPDATE #1: I thought the id was the only attribute not retaining its value but realized that setting any attribute for a ListItem gets set to nil. list.rb: class List < ActiveRecord::Base has_many :list_items, :dependent => :destroy accepts_nested_attributes_for :list_items, :reject_if => lambda { |a| a[:name].blank? }, :allow_destroy => true end list_item.rb: class ListItem < ActiveRecord::Base belongs_to :list validates_presence_of :name end schema.rb ActiveRecord::Schema.define(:version => 20100506144717) do create_table "list_items", :force => true do |t| t.integer "list_id" t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "lists", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end end

  • [Rails] Calling a method from a view using link_to_function

    - by Jeff
    Hello! I'm trying to have an image that when clicked associates the selected guideline to a project. I'm using link_to_function which somewhat behaves but I can not get the method I am calling in the link_to_function to redirect to another page. Is there a better way to do this? Below is a bit of my code. I can paste in additional parts if necessary: <% @guidelines.each do |guideline| %> <tr> <td align='center'><%= link_to_function image_tag("../../../images/icons/action_add.png"), add_guideline(guideline) %></td> <td><%=h guideline.title %></td> My GuidelinesController.helper method looks like this: def add_guideline(guideline) @project = Project.find(params[:project_id]) @project.guidelines << guideline @project.save redirect_to dashboard_path #doesn't work :( end
