AddressGeocoder is a Ruby interface to certain Maps APIs that allow you to validate and geocode addresses.

Some APIs may require certain credentials to access.

AddressGeocoder was written and tested on Rails >= 4.2.5. You can install it by adding in to your Gemfile with:

gem 'address_geocoder'

Run the bundle command to install it.

Require the library:

require 'address_geocoder'

Create a client:

client = MapsApi::Google::Client.new

You can set some or all of the address information when or after creating the client (country names are ISO 3166-1 Alpha-2 codes):

client = MapsApi::Google::Client.new(
  country: 'Your country',
  state: 'Your state',
  city: 'Your city',
  postal_code: 'Your postal code',
  street: 'Your street',
  language: 'The language to return your response in',
  api_key: 'Your api key for an API'
)

client.street = 'A different street'

Validating an address:

client.valid_address? # returns true or false

Finding suggested addresses:

client.suggested_addresses # returns a list of addresses that most closely match your inputted addresss

Additional methods:

client.response       # returns the marketplace's actual response
client.address        # returns the current user inputted address
client.former_address # returns the last address that was used in a call, nil if no call has been made.

Currently the only API we have integrated. All validations are done using Google’s Geocoding API. Although an API key is not required, it is recommended to track usage and upgrade your call limit if required. Google provides a maximum of 2,000 free calls per day to either your IP address or API key.

AddressGeocoder sends addresses in varying formats to the Maps API of your choice. A positive response indicates that the address is valid. After a positive response the gem can parse returned elements to suggest a formatted address.

We are open to suggestions and improvements. Just don’t forget to write tests before the pull request.
