similar to: Problem with UUID generated in partial not being unique

Hi all, I am using rails 3.1 and ruby 1.9.3,Now i want to use uuid concept in rails 3 for existing data so i did like :- create_table :posts, :id => false do |t| t.string :uuid, :limit => 36, :primary => true end ActiveRecord::Base.class_eval do # old rails versions set_primary_key ''uuid'' before_create :generate_uuid def generate_uuid self.id =

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

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 often forward IBM DeveloperWorks articles about RoR to this list.

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

I have my application happily generating UUID primary keys using the uuidtools gem. But the auto-generated specifications created by "script/generate rspec_scaffold...", etc, assume that one is using a sequential integer primary key. For those who have hit this same issue, is it just a matter of rewriting the auto-generated specifications to take this into account, or does one have to

I've taken my RH7.1 system, rebuild kernel (2.4.9 with ext3 patches) and followed the ext3 instructions to install. Everything seems to work OK but - df -k doesn't list the ext3 partition (my root partition). Is this a known problem ? If not, how best can I gather diagnostics to identify the source of the problem ? Thanks -- Philip Nelson (teamdba@bojnice.com)

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 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. Here is my gem list in case that helps: actionmailer (2.3.2, 2.2.2) actionpack (2.3.2, 2.2.2) activerecord (2.3.2, 2.2.2)

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 doing some testing with the rails trunk, version I switched to because of memory leaks in 0.13.1 under linux environment. Right now the application is running fast and steady under linux, with no memory leaks using SCGI Rails Runner 0.4.3 from Zed, BUT it has become unusable under Windows (our main development environment) where I am getting a lot of segmentation faults. BUT the problem

Hi, I''m new to RoR and exploring its use with an existing application. One thing I can''t seem to find much detail on is using database triggers. All RoR examples and tutorials I''ve seen are very basic saving data back to a single table. My use case includes a somewhat denormalized DB that uses triggers to store data in multiple tables on occassion. I currently

Hi there I just started my first Merb app and I''m running into some weird things in Specs.

# Proposal Provide a built-in mechanism for obtaining an identifier for the current R session, e.g. > Sys.info()[["session_uuid"]] [1] "4258db4d-d4fb-46b3-a214-8c762b99a443" The identifier should be "unique" in the sense that the probability for two R sessions(*) having the same identifier should be extremely small. There's no need for reproducibility, i.e.
