UniqToken
Generate a unique, random token for Rails.
Installation
Add this line to your application's Gemfile:
gem 'uniq_token'
And then execute:
$ bundle
Or install it yourself as:
$ gem install uniq_token
Usage
Let's say you have a Project model with a “token” string column that you want to be a unique identifier. Just add this to your model.
class User< ActiveRecord::Base
unique_token :token
end
This will generate a random and unique string before each book is created.
You can config length or prefix, suffix in options like this.
unique_token :token, length: 64, prefix: 'begin_', suffix: '_end'
