[英]How to put inline Ruby each loop in an external request?
我使用Rails 3.1和paypal_adaptive( https://github.com/tc/paypal_adaptive )gem来向Paypal发出API请求。 这是交易:我有一个正在控制器中向Paypal发出的请求。 我有一个Items集合(这里是@items),并且我正在尝试为该集合中的每个项目将收件人添加到该请求中。 这是我的代码:
pay_request = PaypalAdaptive::Request.new
data = {
"returnUrl" => "http://testserver.com/payments/completed_payment_request",
"requestEnvelope" => {"errorLanguage" => "en_US"},
"currencyCode" => "USD",
"receiverList" => {"receiver"=>[
@items.each do |item|
{"email"=>"#{Recipient.find_by_id(item.recip_id).email}", "amount"=>"#{item.price}"},
end
]},
"cancelUrl"=>"http://testserver.com/payments/canceled_payment_request",
"actionType"=>"PAY",
"ipnNotificationUrl"=>"http://testserver.com/payments/ipn_notification"
}
pay_response = pay_request.pay(data)
if pay_response.success?
redirect_to pay_response.approve_paypal_payment_url
else
puts pay_response.errors.first['message']
redirect_to failed_payment_url
end
...但这是行不通的。 如何将Ruby语法正确插入此请求中?
(很抱歉标题中的含糊之处。我不确定我要发出什么样的请求(也许是AJAX?)
只需将所有项目收集到一个变量中并将其设置为“ reciever”键的值即可:
recipients = @items.each do |item|
{"email"=>"#{Recipient.find_by_id(item.recip_id).email}", "amount"=>"#{item.price}"}
end
...
"currencyCode"=>"USD",
"receiverList"=>{"receiver"=> recipients},
"cancelUrl"=>"http://testserver.com/payments/canceled_payment_request",
