Ruby | Random uuid() function

Last Updated : 17 Dec, 2019

Random#uuid() : uuid() is a Random class method which checks returns a random v4 UUID (Universally Unique IDentifier).

Syntax: Random.uuid() Parameter: Random values Return: a random v4 UUID (Universally Unique IDentifier).

Example #1 :

Ruby

# Ruby code for Random.uuid() method

# loading library
require 'securerandom'

# declaring Random value
date_a = SecureRandom.uuid

# declaring Random value
date_b = SecureRandom.uuid

# uuid value
puts "Random uuid form : #{date_a}\n\n"

puts "Random uuid form : #{date_b}\n\n"

Output :

Random uuid form : 219474f0-60c5-43b4-8e7f-f91b5c5e1f38

Random uuid form : d6800817-c27b-4651-8d98-dc12eec46706

Example #2 :

Ruby

# Ruby code for Random.uuid() method

# loading library
require 'securerandom'

# declaring Random value
date_a = SecureRandom.uuid

# declaring Random value
date_b = SecureRandom.uuid

# uuid value
puts "Random uuid form : #{date_a}\n\n"

puts "Random uuid form : #{date_b}\n\n"

Output :

Random uuid form : f74b43f6-8b9c-4cd1-aff2-177f517b77aa

Random uuid form : baba4612-6931-46a0-aa8b-7a105fd2f194
