SchemaPlus::PgTypes

SchemaPlus::PgTypes adds better support for PostgreSQL-specific types to ActiveRecord, mapping them to higher-level types instead of raw strings. Currently this only includes the PostgreSQL interval type, which is mapped to ActiveSupport::Duration.

Installation

As usual:

gem "schema_plus_pg_types"                # in a Gemfile
gem.add_dependency "schema_plus_pg_types" # in a .gemspec

Compatibility

SchemaPlus::PgTypes is tested on:

  • ruby 2.3.1 with activerecord 5.0, using postgresql

Usage

This gem adds a little more syntactic sugar for defining PostgreSQL types in your migrations. You can now simply write: 

create_table :events do |t|
  t.interval :event_duration
end

Instead of:

create_table :events do |t|
  t.column :event_duration, :interval
end

The event_duration column will be represented as ActiveSupport::Duration in your model, so you should be able to use it without the usual fuss:

long_events = Event.where(1.hours..10.hours)

SchemaPlus::PgTypes is part of the SchemaPlus family of Ruby on Rails ActiveRecord extension gems.

Development & Testing

Are you interested in contributing to SchemaPlus::PgTypes? Thanks! Please follow the standard protocol: fork, feature branch, develop, push, and issue pull request.

Some things to know about to help you develop and test:

  • schema_dev: SchemaPlus::PgTypes uses schema_dev to facilitate running rspec tests on the matrix of ruby, activerecord, and database versions that the gem supports, both locally and on travis-ci

To to run rspec locally on the full matrix, do:

    $ schema_dev bundle install
    $ schema_dev rspec

You can also run on just one configuration at a time; For info, see schema_dev --help or the schema_dev README.

The matrix of configurations is specified in schema_dev.yml in the project root.

  • schema_plus_core: SchemaPlus::PgTypes uses the SchemaPlus::Core API that provides middleware callback stacks to make it easy to extend ActiveRecord's behavior. If that API is missing something you need for your contribution, please head over to schema_plus_core and open an issue or pull request.
  • schema_monkey: SchemaPlus::PgTypes is implemented as a schema_monkey client, using schema_monkey's convention-based protocols for extending ActiveRecord and using middleware stacks.
