我在Rails应用程序中遇到上述错误。我的预订模式中有以下条带代码 -
booking.rb
class Booking < ActiveRecord::Base
belongs_to :event
belongs_to :user
validates :quantity, presence: true, numericality: { greater_than: 0 }
validates :event, presence: true, numericality: {greater_than_or_equal_to: 0 }
before_save :set_price_to_zero_if_free
def set_price_to_zero_if_free
self.event.price >= 1 unless self.event.is_free
end
def reserve
# Don't process this booking if it isn't valid
#return unless valid?
# We can always set this, even for free events because their price will be 0.
#self.total_amount = booking.quantity * event.price
# Free events don't need to do anything special
if event.is_free?
save!
# Paid events should charge the customer's card
else
begin
charge = Stripe::Charge.create(
amount: total_amount,
currency: "gbp",
source: 'token',
description: "Booking created for amount #{total_amount}")
self.stripe_charge_id = charge.id
save!
rescue Stripe::CardError => e
errors.add(:base, e.message)
false
end
end
end
end
bookings_controller.rb
class BookingsController < ApplicationController
before_action :authenticate_user!
def new
# booking form
# I need to find the event that we're making a booking on
@event = Event.find(params[:event_id])
# and because the event "has_many :bookings"
@booking = @event.bookings.new(quantity: params[:quantity])
# which person is booking the event?
@booking.user = current_user
#@booking.quantity = @booking.quantity
#@total_amount = @booking.quantity.to_f * @event.price.to_f
end
def create
# actually process the booking
@event = Event.find(params[:event_id])
@booking = @event.bookings.new(booking_params)
@booking.user = current_user
if
@booking.reserve
flash[:success] = "Your place on our event has been booked"
redirect_to event_path(@event)

flash[:error] = "Booking unsuccessful"

我不明白为什么当我在条带代码中清楚地包含source时，我会收到错误。我已经在上面表达了self.stripe_token，但我只尝试过stripe_token，但仍然得到同样的错误。我的理解是我需要提供来源或客户，而不是两者，并且它需要是来源而不是客户。
我错过了什么？
答案 0 :(得分：0)
如果您收到“必须提供来源或客户”作为错误消息，则表示代码中的self.stripe_token必须是nil或空字符串。
您需要确保source参数的值是有效的令牌ID。应使用Checkout或Stripe.js在客户端创建令牌。创建令牌后，您需要将其发送到您的服务器（通常作为POST参数），以便您可以在charge creation request中使用它。
您还可以在信息中心中查看帐户的日志，以查看集成发送的请求，这在调试问题时非常有用：https://dashboard.stripe.com/test/logs/overview。

我猜测stripe_token不是booking模型中的属性。这就是为什么当您尝试使用self.stripe_token检索它的价值时，它会为您提供nil。
尝试将令牌从控制器参数传递给模型实例方法：
if @booking.reserve(booking_params['stripe_token'])
# everything is good
else
# ops
end
def reserve(stripe_token)
if event.is_free?
save!
else
begin
charge = Stripe::Charge.create(
amount: total_amount,
currency: "gbp",
source: stripe_token,
....
)
# rest of method
end
目前您的代码中有total_amount被注释掉的部分！
total_amount = self.booking.event.price * 100 #not really sure how should calculate this?
charge = Stripe::Charge.create(
amount: total_amount,
currency: "gbp",
source: 'token',
description: "Booking created for amount #{total_amount}"
)
