Rails/Stripe - отсутствует ошибка шаблона в контроллере заказов

Question

Я создаю приложение событий с использованием Rails, и я пытаюсь создать код, который сначала проверяет, что пробелы доступны, когда пользователь пытается заказать, и если да, то принимает их, чтобы забронировать мероприятие. я попал следующее сообщение об ошибке при попытке сделать бронирование -

бронирований Недостающие шаблоны/создать

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

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

Я не уверен, что это не имеет ничего общего с ситуацией на бронирование в течение, как должно быть Я думаю, что это больше связано с кодом Stripe. Вот соответствующий код -

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

Вы не должны сохранить номер, а затем проверить счета. Вместо этого вы можете это сделать.

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 
     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
