Earning My Keep

Now I'm earning my keep.

Trying to get your sample_transaction.rb up and running I got this error:

➜  activemerchant-demo  ruby sample_transaction.rb
/home/nathan/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/activemerchant-1.42.6/lib/active_merchant/billing/gateways/authorize_net.rb:288:in `success?': undefined method `exclude?' for ["310", "311"]:Array (NoMethodError)
	from /home/nathan/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/activemerchant-1.42.6/lib/active_merchant/billing/gateways/authorize_net.rb:278:in `commit'
	from /home/nathan/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/activemerchant-1.42.6/lib/active_merchant/billing/gateways/authorize_net.rb:117:in `purchase'
	from sample_transaction.rb:30:in `<main>'

So, I dug into the ActiveMerchant source code and found it was coming from here:

def success?(response)
  response[:response_code] == APPROVED && TRANSACTION_ALREADY_ACTIONED.exclude?(response[:response_reason_code])
end

That TRANSACTION_ALREADY_ACTIONED constant is an Array:

TRANSACTION_ALREADY_ACTIONED = %w(310 311)

The second part of the && statement was added just a few weeks ago.

But, there's no exclude? method on a ruby array!!!

*googles ruby exclude? method*

Aha! The exclude? method is added to Enumerable by ActiveSupport! This code will only work in Rails!!

Or... we can add require 'active_support/all' to sample_transaction.rb.

➜  activemerchant-demo  ruby sample_transaction.rb
The transaction was successful!  The authorization is 2207330213
{"response_code"=>1, "response_reason_code"=>"1", "response_reason_text"=>"This transaction has been approved.", "avs_result_code"=>"Y", "transaction_id"=>"2207330213", "card_code"=>"P", "authorization_code"=>"WQQA6J", "cardholder_authentication_code"=>"2", "action"=>"AUTH_CAPTURE"}
