This gem is an extension of Rails ActiveRecord Enum. It adds 2 new methods on records and 2 new scopes.

If we take a Book class that have the following enum: enum status: { submitted: 0, approved: 1, published: 2 }, then we define:

• Book.before_published that returns every Book where the status is before published
• Book.after_published that returns every Book where the status is after published
• new_book.before_published? that returns true if new_book status is before published
• new_book.after_published? that returns true if new_book status is after published

The main goal of this gem is to replace the new_book.status_before_type_cast < Book.statuses['published'] syntax that I find way too verbose and annoying to write.

Add this line to your application's Gemfile:

gem 'temporal_enum'

And then execute:

bundle install

Just add the option temporal: true to your existing enum, for exemple

enum status: { 
  submitted: 0, 
  approved: 1, 
  published: 2 
}, temporal: true

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
