Parse Payment gem response

Rails
1

I’m using the Payment gem to submit authorizenet cCards at their test
server.
Working fine except I cant seem to parse the gateway response in any
usable way except in a flash[:notice]

so i get this from authorize.net

‘This transaction has been approved.’
Response codes:
authorization: ‘r6LUBy’
result code: 0
avs code: ‘Y’
transaction id: ‘507082976’
md5: ‘3F55F20B96D9ED123CADCC1828EA9F2A’
cvv2 response: ‘P’
cavv response: ‘2’

from this:

“

#{transaction.error_message}


Response codes:


  • authorization: #{transaction.authorization}

  • result code: #{transaction.result_code}

  • avs code: #{transaction.avs_code}

  • transaction id: #{transaction.transaction_id}

  • md5: #{transaction.md5}

  • cvv2 response: #{transaction.cvv2_response}

  • cavv response: #{transaction.cavv_response}


”

But i can’t seem to get any of the responses like
transaction.error_message
into any var I can store or use.

when I try this

@auth = transaction.authorization

I just get nil

Can someone clue me in as to how to parse this?
