It still works and may be useful to you for Rails versions < 5, but will not be updated to be compatible with Rails version > 5.

Adds missing native PostgreSQL data types to ActiveRecord and convenient querying extensions for ActiveRecord and Arel for Rails 4.x

If it is a bug please open an issue on Github. If you need help using the gem please ask the question on Stack Overflow. Be sure to tag the question with DockYard so we can find it.

Add this line to your application's Gemfile:

gem 'postgres_ext'

And then execute:

$ bundle

Or install it yourself as:

$ gem install postgres_ext

Just require 'postgres_ext' and use ActiveRecord as you normally would! postgres_ext extends ActiveRecord's data type handling and query methods in both Arel and ActiveRecord.

• Querying PostgreSQL datatypes

Where are the datatypes from PostgresExt 1.x? ActiveRecord 4.x includes all the data types that PostgresExt added to ActiveRecord 3.2.x. We'll be adding more datatypes as we come across them.

To work on postgres_ext locally, follow these steps:

1. Run bundle install, this will install (almost) all the development dependencies
2. Run gem install byebug (not a declared dependency to not break CI)
3. Run bundle exec rake db:setup, this will set up the .env file necessary to run the tests and set up the database
4. Run bundle exec rake db:create, this will create the test database
5. Run bundle exec rake db:migrate, this will set up the database tables required by the test
6. Run BUNDLE_GEMFILE='gemfiles/Gemfile.activerecord-4.0.x' bundle install --quiet to create the Gemfile.lock for 4.0.
7. Run BUNDLE_GEMFILE='gemfiles/Gemfile.activerecord-4.1.x' bundle install --quiet to create the Gemfile.lock for 4.1.
8. Run bundle exec rake test:all to run tests against all supported versions of Active Record
