Ajax提交问题-Rails [英] Ajax Submit issue - Rails

问题描述

我不认为我的解决方案可以通过Rails UJS提交braintree事务，而Ajax是正确的，原因是我在提交时看到两个ajax调用，而不是一个.

I am not convinced my solution to submit a braintree transaction via Rails UJS and Ajax is correct, the reason being is i am seeing two ajax calls as opposed to one when submitting.

例如，当关闭ajax(因此删除remote:true)时，提交表单似乎要等待现时才提交付款(我相信braintree会接管提交事件)

For example when turning ajax off (so removing remote: true) submitting a form seems to wait for a nonce before submitting the payment (I believe braintree takes over the submit event)

Parameters: {"utf8"=>"✓", "authenticity_token"=>"token_here", "first_name"=>"", "last_name"=>"", "payment_method_nonce"=>"nonce_here_populated"}

但是当使用远程提交时:启用true的第一个呼叫是

But when submitting with remote: true enabled the first call is

Parameters: {"utf8"=>"✓", "authenticity_token"=>"token_here=", "first_name"=>"", "last_name"=>""} 

所以我读到我需要使用 onPaymentMethodRecieved 回调函数等待该随机数，将随机数附加到表单上，然后提交

So i read that i need to wait for that nonce using the onPaymentMethodRecieved callback function, append the nonce to the form and then submit

braintree.setup(gon.client_token, 'dropin', {
  container: 'dropin-container',
  onPaymentMethodReceived: function (paymentMethod) {
   $('#braintree-transaction-form').append("<input id='p_nonce' type='hidden' name='payment_method_nonce' value='" + paymentMethod.nonce + "'></input>");
   $("#braintree-transaction-form input[type='submit']").submit();
  }
});

这导致拨打了两个电话

1)

Parameters: {"utf8"=>"✓", "authenticity_token"=>"token_here=", "first_name"=>"", "last_name"=>""}

2)

Parameters: {"utf8"=>"✓", "authenticity_token"=>"token_here", "first_name"=>"", "last_name"=>"", "payment_method_nonce"=>"nonce_here_populated"}

唯一的问题是我的控制器中有这个，认为不正确

Only problem being is i have this in my controller which dont think is correct

def create
  nonce = params[:payment_method_nonce]
  render action: :new and return unless nonce # Is this the way to wait for the nonce
  @result = Braintree::Transaction.sale(
              amount: 2500,
              payment_method_nonce: nonce,
              customer: {
                first_name: params[:first_name],
                last_name: params[:last_name]
             }
            )
end

我担心的是我正在拨打两个电话以及我的控制器代码.

my concern i guess is the two calls being made and my controller code.

任何人都可以使用Braintree和Rails进行Ajax调用

Has anyone got any experience with Ajax calls with Braintree and Rails

谢谢

推荐答案

_{完整披露:我在Braintree工作.如果您还有其他疑问，请随时与支持.}

您可能会遇到提交按钮默认行为的问题，即默认行为您可以尝试禁用.但是，这里没有任何东西可以认为是问题所在.最有可能是您的设置中的其他地方出现了问题.我真的建议您与您的完整代码示例联系 Braintree支持，以帮助他们解决您的问题.

You might be running into a problem with the default behavior of your submit button, which is something you could try disabling. However, there's nothing here to think that is the issue. Most likely there is a problem elsewhere in your setup. I would really recommend contacting Braintree support with your full code samples to help them walk through your issue.
