在我的网站上，用户以相同的形式注册并提供其信用卡信息。表单使用Devise来保存用户。我需要将实际的设计代码导入控制器（一个不好的做法，我知道，但是对于Braintree，我看不到任何其他方式来包装用户并收取一笔交易）。我终于完成了所有工作，除了我遇到Braintree错误消息的问题。我刚尝试创建一个金额为2600美元的交易，它应该触发Braintree错误并显示一条消息，但是没有触发这样的错误。这是我的代码：
def create
nonce_from_the_client = params[:payment_method_nonce]
# code taken from devise
build_resource(sign_up_params)
begin
@charge = resource.charges.build
@charge.nonce = nonce_from_the_client
braintree_call = nil
@braintree_errors = nil
ActiveRecord::Base.transaction do
puts "beforer resource saved".green
resource.save!
puts "resource saved".green
puts "charge built".green
puts "before call_braintree".green
braintree_call = @charge.call_braintree!
if braintree_call.success? && !braintree_call.errors.any?
puts "braintree_call was a success".green
@charge.save
#do nothing. All good
else
puts "braintree error".red
@braintree_errors = braintree_call.errors
braintree_call.errors.each do |error|
puts "#{error.code}\n".red
puts "#{error.message}".red
end
raise "@Charge Failed"
end
end
rescue
puts "@charge #{@charge.inspect}".red
puts "@charge errors: #{@charge.errors.inspect}".red
end
yield resource if block_given?
if resource.persisted?
puts "resource persisted".green
if resource.active_for_authentication?
flash[:success] = "Welcome! You have signed up successfully."
# set_flash_message! :notice, :signed_up
sign_up(resource_name, resource)
respond_with resource, location: after_sign_up_path_for(resource)
else
puts "not sure about this".blue
# set_flash_message! :notice, :"signed_up_but_#{resource.inactive_message}"
flash[:danger] = "signed_up_but_#{resource.inactive_message}"
expire_data_after_sign_in!
respond_with resource, location: after_inactive_sign_up_path_for(resource)
end
else
puts "resource did not persist".red
clean_up_passwords resource
set_minimum_password_length
# respond_with resource
puts "NOW WE KNOW".on_red
render 'new' #not sure if this works
end
puts "resource errors are #{resource.errors.inspect}".red
end
以下是Charge的模型，其中包含上面的call_braintree方法：
class Charge < ActiveRecord::Base
belongs_to :user
attr_accessor :nonce
after_create :activate_user_account
def activate_user_account
puts "in the activate user account after_Create method".green
self.user.activate
end
def set_amount
amount = self.user.plan.amount * self.user.plan.length
puts "amount is #{amount} and is class #{amount.class}".green
return amount
end
def call_braintree!
puts "in call braintree".green
result = Braintree::Transaction.sale(
:amount => "#{self.set_amount}",
:payment_method_nonce => self.nonce,
:options => {
:submit_for_settlement => true
}
)
end
end

我为了获得braintree错误而做的唯一不同的事情是使用2600切换call_braintree方法中的金额。
正如您在日志中看到的那样，抛出了某种类型的错误或调用没有成功，但Braintree没有提供错误。每当用户卡无法工作时，无论出于何种原因，我都需要来自braintree的错误消息来向用户显示。如何正确显示braintree错误？
答案 0 :(得分：0)
完全披露：我在Braintree工作。如果您有任何其他问题，请随时与我们的support小组联系。
仅为Braintree验证错误填充错误。处理程序错误在交易processor_response_code
在处理器级别失败的事务的适当错误处理如下所示：
if braintree_call.success? && !braintree_call.errors.any?
puts "braintree_call was a success".green
@charge.save
#do nothing. All good
elsif braintree_call.transaction
puts "Transaction processing error: #{braintree_call.transaction.status}: Response Code: #{braintree_call.transaction.processor_response_code}\n".red
raise "@Charge Failed"
else
puts "braintree error".red
@braintree_errors = braintree_call.errors
braintree_call.errors.each do |error|
puts "#{error.code}\n".red
puts "#{error.message}".red
end
raise "@Charge Failed"
end
