Hello, It seems that there is a small probability of collisions among uuid''s produced by uuidtools'' UUID.random_create() running in concurrent user processes on a host (fcgi)? The ~2 bytes extracted from the randomized clock_sequence make a collision unlikely. http://rubyforge.org/frs/download.php/8572/uuidtools-1.0.0.zip Do I miss something? DD -- Posted via

Hi, I am using UUIDTools to generate my Guids. It works fine on my computer (Windows Xp), but doesn''t work on my host (TextDrive) The error is: Loading production environment. >> UUID.timestamp_create.to_s /sbin/ifconfig: Permission denied NoMethodError: private method `split'' called for nil:NilClass from ./script/../config/../config/../lib/uuidtools.rb:236:in

I need to create certain number of UUId records(based on the selection of drop down) and save it in the database. Now I am generating only one unique id. Can this be done in the model in this way. Or do I need to write a helper file for that?? def generate_unique_token=(value) self.secret = Base64.encode64(UUIDTools::UUID.random_create)[0..8] end In my controller........... def create

Greetings, I''m new to rails and currently having couple problems about how to add javascript functionality into rails.

Folks, I''m using the "uuidtools" package to generate (hopefully) unique values for IDs within a partial (for products being added to an order form, where nothing is saved to the DB until the end). Unfortunately when I add a new product line (using RJS page.insert.html rendering a partial) the new lines added all have the same UUID. Here''s the code from the (top of

Hi everyone, I''m trying to use ajax to update the selected value of a select element. Here''s what I have so far: function RailsModel(model_name) { this.model_name = model_name; } RailsModel.prototype.getAttributeById = function(attribute, id) { Ajax.Request(''/models/get_attribute_by_id/'' + this.model_name + ''/'' + attribute +

Hi all, In my controller I am doing the following to populate a nested form for a has_many through association: def new @specification = Specification.new Component.find_each.each do |component| @specification.component_specifications.build(:component_id => component.id) end The idea being whenever someone creates or edits a form, it will be populated with all

Hi everyone, We''re running a fairly heavily used Rails app that uses ferret (and acts_as_ferret) for search. We''re running on mongrel+Apache, Ruby 1.8.4, and ferret 0.10.13. We''re indexing a handful of attributes on our "Image" and "User" models. After the system has been running for several days, the index gradually becomes corrupted, and ferret

Hello, At guides.rubyonrails.org I read about the possibilities of find_in_batches. However I cannot find this option anywhere in the API documentation (api.rubyonrails.org). My question: where should I look for the documentation of this command? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Why would, in an upgrade from 3.0.1 to 3.0.3, a rake db:migrate run this: SELECT "schema_migrations"."version" FROM "schema_migrations" vs this ? SELECT `schema_migrations`.`version` FROM `schema_migrations` __ rake db:migrate output __ rake aborted!

Hi, today I went into a problem, when I had to iterate over a big result set. ActiveRecord produces a huge array of model instances, which consumed 1GB of memory on my machine. A comparable perl DBI script only used some KB for iterating over the result set. Then I was suggested to use batch (#find_each) for the problem. But basically batch does the same thing by splitting the query into several

I am relatively new to RoR and Ruby for that matter. A few questions for the pros: Question 1: In the 5min ajax video the presenter uses <%= yield %> in his layout. In the agile book, @content_for_layout is used. Since, yield is an actual Ruby construct, is it more efficient and preferred? What is the difference? Question 2: Links are often of the form :action =>

Hello everyone, Nice to meet you all, am new to the forum. I''m stuck with rake / actionmailer trying to display a set of found records. We have a simple actionmailer rake task that is supposed to send a daily email digest of tasks that are due for a specific user. So far, it''s working but the email only displays the first message. In my task model scope :tasksdue, lambda {

Hi folks, I am running an offline Rails app that periodically connects to the Internet to download the latest catalogue, and upload any new orders. I am about to implement the synching bit - and was thinking whether there is any other solution other than writing webservices and code to do a manual sync of the data, or whether there is a more nifty and robust way using say replication?

When I run rake test:units I get this error: 292 tests, 350 assertions, 2 failures, 13 errors rake aborted! Command failed with status (1): [/usr/local/bin/ruby -I"lib:test" "/ usr/loc...] This error just showed up yesterday --- I have no idea how I caused it.

I have an issue where I am getting a large number of records from the database and I cant afford to keep it in the memory due to performance issues. Therefore using the following would be ideal, User.find_each(:batch_size => 5000, :start => 2000) do |user| NewsLetter.weekly_deliver(user) end however, I would like to use find_by_sql since my query is user defined. Question is, is it

Does puppet doc require a specific version of any gems (such as rdoc or rake) to operate? I''m getting some errors when I try to generate my rdoc now. # puppet doc --output /var/www/test --modulepath /etc/puppet/environments/test/modules -m rdoc RDoc::RDocError is deprecated and will be removed in RDoc 4 Could not generate documentation: uninitialized constant RDoc::RDoc::Generator

I am a little confused about the best way to work with date_select. I see that in my views it generates a simple input form that allows for the entry of year, month and date information. If I just leave it at that, great! But what if now in the controller, I want to work with the date information. I actually want to take the user input date and compute a new date some number of days in the

I''m using Sequel as my ORM and Test::Unit as my testing framework and have the following model: class Item < Sequel::Model validates do presence_of( :name, :uuid, :vendor_id, :vendor_reference, :amount, :currency_code ) uniqueness_of( :uuid ) end def initialize( *args ) super( *args ) self.uuid = UUID.random_create.to_s end end As you can see I overwrite
