Question

我正在使用Rails构建一个事件应用程序，而我正在尝试创建代码，该代码首先检查用户尝试预订时是否有空格，如果是，则将其用于预订事件。我在尝试预订时遇到以下错误 -

缺少模板预订/创建

def find(*args)
  find_all(*args).first || raise(MissingTemplate.new(self, *args))
end

def find_all(path, prefixes = [], *args)

我不确定这与预订情况有什么关系，因为应该有空位。我认为这更多地与Stripe代码有关。这是相关代码 -

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
    # 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
    #@total_amount = @booking.quantity.to_f * @event.price.to_f

    Booking.transaction do
        @booking.save!
        @event.reload
        if @event.bookings.count > @event.number_of_spaces
            flash[:warning] = "Sorry, this event is fully booked."
            raise ActiveRecord::Rollback, "event is fully booked"
        else
            if @booking.save

                # CHARGE THE USER WHO'S BOOKED
                # #{} == puts a variable into a string
                Stripe::Charge.create(amount: @event.price_pennies, currency: "gbp",
                    card: @booking.stripe_token, description: "Booking number #{@booking.id}")

                flash[:success] = "Your place on our event has been booked"
                redirect_to event_path(@event)
            else
                flash[:error] = "Payment unsuccessful"
                render "new"
            end

            if @event.is_free?

                @booking.save!
                flash[:success] = "Your place on our event has been booked"
                redirect_to event_path(@event)
            end

        end 
    end


end


#def total_amount
    #@total_amount = @booking.quantity * @event.price
#end

private

def booking_params
    params.require(:booking).permit(:stripe_token, :quantity)
end



end

您不应保存预订，然后检查计数。相反，你可以这样做。

val window = Window.partitionBy("uid").orderBy("time")
val change = ((lag("code", 1).over(window) <=> "c")).cast("int")

Rails / Stripe - 预订控制器中缺少模板错误
