I need to generate uuid for my rails application. What are the options(gems) I have? [duplicate]
I use Rails 3.0.20 and ruby 1.8.7 (2011-06-30 patchlevel 352)
Please suggest me the best plugin to generate guid.
There are plenty of options, I recommend not to add additional dependencies and use SecureRandom which is builtin:
SecureRandom.uuid #=> "1ca71cd6-08c4-4855-9381-2f41aeffe59c"
See other possible formats here.
The first thing I would suggest is that please upgrade your ruby and rails version.
A very good way of generating guid is SecureRandom, which is a ruby module. With easy usage.
require 'securerandom'
guid = SecureRandom.hex(10) #or whatever value you want instead of 10
I would suggest using PostgreSQL and using the uuid column built in, it autogenerates UUID based on type you create the column.
Example in Rails 3 migration
execute <<-SQL
CREATE TABLE some_items (id uuid PRIMARY KEY DEFAULT uuid_generate_v1());
SQL
Might be a better way to do this in Rails 4.
