How to obfuscate user id with random number using friendly_id

When my new website launches there will be very few users. Currently a user's profile page is /users/:id so in the early stages it will be /users/6, etc. I don't want others to know how many users the website has. I think that an long id (such as a uuid) with numbers and letters looks ugly so I would prefer it just be numbers.

How can I use friendly_id gem to create a random number slug that will also be unique? This is also my first website so any "best practices" tips regarding user id obfuscation would be helpful. Thanks.

This is an example from existing project:

class User < ActiveRecord::Base
  extend FriendlyId
  friendly_id :email, use: [:slugged, :finders]

  def normalize_friendly_id(email)
    Digest::MD5.hexdigest(email)
  end

  def should_generate_new_friendly_id?
    slug.blank?
  end
end

You can change the MD5 to a random number using something like this:

SecureRandom.random_number(1_000_000_000)
