rails secure uuid
To secure a UUID in Ruby on Rails, you can follow these steps:
Add the
uuid
gem to your Gemfile by including the following line:ruby gem 'uuid'
Run the
bundle install
command in your terminal to install the gem.In your model file (e.g.,
app/models/user.rb
), add theuuid
column to your table by using theadd_column
method in a migration:ruby class AddUuidToUsers < ActiveRecord::Migration[6.0] def change add_column :users, :uuid, :uuid, default: 'gen_random_uuid()', null: false end end
Run the migration to add the
uuid
column to your database by executing the following command in your terminal:rails db:migrate
In your model file, include the
has_secure_token
method to generate a secure UUID token for each record:ruby class User < ApplicationRecord has_secure_token :uuid end
Save and restart your Rails server for the changes to take effect.
Now, you have a secure UUID for each record in your users
table. You can access the UUID for a user instance using user.uuid
. This UUID will be unique and difficult to guess, providing added security for your application.
