Я впервые пользуюсь услугами rails. До изменения мой код был в беспокойстве.
Проблема в том, что в одном из моих методов мне нужно установить атрибут модели, и я не уверен, как мне это сделать из службы.
В моем контроллере:
def new
@order = Order.new(default_order_create_params)
@pricing = PricingComputed.new(order: @order, user: current_user)
end
С моего сервиса (я удалил ненужный код):
# frozen_string_literal: true
class PricingComputed
def initialize(params)
@order = params[:order]
@user = params[:user]
end
def perform
set_discounted_price_pretax_cents
end
private
def set_discounted_price_pretax_cents
return unless @order.pending?
@order.discounted_price_pretax_cents = @order.price_pretax_cents - discount_cents
end
end
Я хочу иметь возможность установить discounted_price_pretax_cents и использовать его с @pricing, если это возможно.
Не могли бы вы указать мне?
EDIT:
на мой взгляд (новый):
= render('steps/price_card', order: @order, pricing: @pricing)
_price_card:
#order-price-card.neo-card
.neo-card-heading
h2.neo-card-title
| Your order
- if order.cash?
.neo-card-price-reduction
.neo-card-list-item
.neo-card-list-item-label

- if pricing.discount_cents.positive?
strong
=> number_to_currency(pricing.discount)
small
= "(#{number_to_percentage(pricing.discount_percent, precision: 2)})"
- else
