DCMetro

Rails class and a command line interface to access the Washington, D.C. Metro Rail API. Returns the systemwide alerts, lines, stations and arrival times for the lines at each station.

Add this line to your application's Gemfile:

gem 'dcmetro'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dcmetro

The variable needs to be set to DCMETRO_KEY

It is recommended that a key is requested from https://developer.wmata.com/

For the CLI, in the .bash_profile set the following: EXPORT DCMETRO_KEY = <<replace with api key from WMATA>>

Don't forget to source .bash_profile after making the changes.

With the gem installed, instantiate a new class in your controller:

class WelcomeController < ApplicationController

  def index
    dc_metro = DCMetro::Information.new
    @alerts = JSON.parse dc_metro.alerts
    @lines = JSON.parse dc_metro.line
    @stations = JSON.parse dc_metro.line "green"
    @college_park = JSON.parse dc_metro.station "college"
    @gallery_place = JSON.parse dc_metro.station "gallery"
    #
    # New in 0.0.3 - kind of a work in prorgress
    @fare_info = JSON.parse dc_metro.station "college", "gallery"
  end

end
