Get a MapQuest API key, and store in your app under MAPQUEST_KEY
MAPQUEST_KEY = ‘your_api_key’
directions = MapQuestDirections.new(origin, destination)
where origin and destination are strings of addresses or places that MapQuest can find an address for. Example: “816 Meridian St., 37207”
Get drive time or distance of whole trip
drive_time_in_minutes = directions.drive_time_in_minutes
distance_in_miles = directions.distance_in_miles
Get the XML MapQuest returns with every turn, or the API call URL
xml = directions.xml
xml_call = directions.xml_call
directions.statusshows you the status code returned by MapQuest. 0 means worked. Other codes (500, 403) mean problem.
If MapQuest can’t recognize your places or gives an error, the distance_in_miles and drive_time_in_minutes will each return 0. You can call
directions.statusand it should tell you a number code for the problem. You can call
directions.xmlto read the full text.

Tested on Rails 2.3.8
Not yet tested on Rails 3. It probably is Rails 3 compatible, because it’s just a single class with a few methods. It’s probably compatible with every ruby project ever.
MapQuest maps API key
You’ll need a MapQuest Map API key
Include it as the constant MAPQUEST_KEY in an app configuration file (environment.rb, config/initializers/api_keys.rb)
Need turn-by-turn directions?
Not yet included in this gem, but you can do it with nokogiri to parse the XML that comes back when you do
And then nokogiri can cycle through each and you can pick out what you need.
Anyone can use this code in any way.
