私はモデルPayment
を使用して、クレジットカード取引を追跡します。今、私はPayPalが成功したクレジットカード取引で返すいくつかの価値をマップするようにしています。これはnotify = ActiveMerchant::Billing::Integrations::Paypal::Notification.new(raw_post)
(長さが長い)Rails - モデルはメソッドを通じて属性を保存しませんが、手作業で割り当てる場合(コンソールで)
によって処理されますが、私が書いた方法はコンソールでは機能しません。しかし、私がそれらを直接割り当てた場合、それは機能します。
Railsのコンソール
notify = ActiveMerchant::Billing::Integrations::Paypal::Notification.new(raw_post)
# Works
payment = Payment.new
payment.raw_response = notify.raw
save! # Save is successful
# Does not work
payment = Payment.new
payment.map_paypal_return(notify) # save! call in this method does not trigger errors.
私のクラスを見てみてください。コンソールで
class Payment < ActiveRecord::Base
belongs_to :order
def map_paypal_return(notify)
puts "in mapping" => Outputted
raw_response = notify.raw
payment_status = notify.status
order_identifier = notify.item_id # Map ID to ID as a safety check bah.
payer_email = notify.params["payer_email"]
receiver_account = notify.account
auth_mode = notify.params["payment_type"]
transaction_identifier = notify.invoice
currency = notify.currency
amount = notify.gross
puts self.attributes # Returns attributes without the above assignments
save! # No errors triggered =(
end
end
メソッドの呼び出し
1.9.2p318 :032 > notify.invoice # This should have been mapped to transaction_identifier
=> "2012-146"
1.9.2p318 :031 > p.map_paypal_return(notify)

私はどこかのRuby/Railsのの愚かな根本的な誤解をした場合、私は知りません。本当に助けに感謝します。
私はいつも、インスタンスメソッドのときにselfキーワードは必要ないと思っていました。ああ、コードの最後の数週間! –
