UniqIdentifier

(Travis CI)

Add an uniq identifier on your models. For make your model agnostic from backend unique identifier.

Add this line to your application's Gemfile:

gem 'uniq_identifier'

And then execute:

$ bundle

Or install it yourself as:

$ gem install uniq_identifier

add uuid in your model like that:

class Foo < ActiveRecord::Base
  uniq_identifier
end

foo = Foo.new
foo.id   # => nil
foo.uuid # => "0c6bbc03-a269-44e2-8075-f442e1aac0c8"

foo.create!
foo.id # => 1
foo.uuid # => "0c6bbc03-a269-44e2-8075-f442e1aac0c8"

my_foo = Foo.where(uuid: "0c6bbc03-a269-44e2-8075-f442e1aac0c8")
my_foo.id # => 1

add app/config/initializers/uniq_identifier.rb

UniqIdentifier.configuration do |conf|
  conf.generator = SecureRandom
end

you can use the generator

rails g uniq_identifier:install
rails g uniq_identifier:add <model>

for mongoid use

rails g uniq_identifier:add <model> --orm=mongoid

class CustomGenerator
  def uuid
    # ...
  end
end

class Bar
  uniq_identifier generator: CustomGenerator,
                  auto: bool,
                  validate: bool
end

• generator can be any object which respond to uuid signal or :default (default: :default)
• auto if set to false then uuid will not be automatically generated after initialize (default: true)
• validate if set to false validation will not be added (default: true)
