我有以下charge.rb:
class Charge < ActiveRecord::Base
serialize :response, Hash
include HTTParty
belongs_to :order
def charge_url
return "#{Pin.base_url}/1/charges"
end
def submit(ip)
@authorization = {:username => Pin.secret_key, :password => Pin.public_key}
@params = {
'currency' => "USD",
'description' => "One Testivate Retail Site Search Benchmark report",
'amount' => 99900,
'ip_address' => (ip),
'email' => self.order.user.email,
'card' => {'number' => self.number,
'expiry_month' => self.expiry_month,
'expiry_year' => self.expiry_year,
'cvc' => self.cvc,
'name' => self.name,
'address_line1' => self.address_line1,
'address_line2' => self.address_line2,
'address_city' => self.address_city,
'address_postcode' => self.address_postcode,
'address_state' => self.state,
'address_country' => self.country }}
response = HTTParty.post(self.charge_url, :query => @params, :basic_auth => @authorization)
self.update_attributes :token => response["response"]["token"], :display_number => response["response"]["display_number"], :response => response
end
end
当我在控制台中调用 self 的提交方法时,我得到了这个:
[30] pry(#<Charge>)> self

如果我再次向上,我最终会进入提交方法。在 charge.rb 模型中没有明确定义回调。我到底怎么才能找到不会保存的 NilClass?
