Airports

Airports gives you access to data on airports around the world from your Ruby applications.

It's based on data from OpenFlights, with a bit of massaging on the way (dropping airports without an IATA code, giving Doha its IATA code and adding HYD and BER which are missing entirely).

Install the gem by adding it to your Gemfile:

gem "airports", "~> 1.9.0"

You can then look up an airport by its IATA code (e.g. LHR for London Heathrow) using Airports.find_by_iata_code, which returns an object with a bunch of accessors like name and city:

Airports.find_by_iata_code("LHR")
=> #<Airports::Airport:0x00007fdbd1df68d0 @name="London Heathrow Airport", @city="London", @country="United Kingdom", @iata="LHR", @icao="EGLL", @latitude="51.4706", @longitude="-0.461941", @altitude="83", @timezone="0", @dst="E", @tz_name="Europe/London">

You can also look up an airport by its ICAO code.

Airports.find_by_icao_code("KCRG")
=> #<Airports::Airport:0x00007fdbd1d955d0 @name="Jacksonville Executive at Craig Airport", @city="Jacksonville", @country="United States", @iata="CRG", @icao="KCRG", @latitude="30.3362998962", @longitude="-81.51439666750001", @altitude="41", @timezone="\\N", @dst="\\N", @tz_name="\\N">

A couple of other methods provide access to aggregate data.

You can call Airports.iata_codes for a list of valid IATA codes, perfect for Rails validations:

validates :destination_airport, inclusion: { in: Airports.iata_codes, message: "is not a valid airport" }

Or Airports.all will provide Airports::Airport objects representing all the airports the gem knows about.

After checking out the repo, run bin/setup to install dependencies. Then, run rake rspec 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 tags, and push the .gem file to rubygems.org.

To update the data included in the gem, just run bundle exec rake update and make a pull request with the changes. This will pull the latest data from OpenFlights.
