Codeclimate rails Similar code: how to optimize?

Question

Ruby on Rails

I decided to start using codeclimate in one of my projects. In the entire project, he found only 1 "darling"

def delivery_method=(deliver)
    unless product.shop.delivery_methods.include? deliver
      raise ArgumentError.new('This product does not contain delivery method')
    end
    self.delivery_method_id = deliver.id if deliver.kind_of?(DeliveryMethod)
end

def payment_method=(payment)
    unless product.shop.payment_methods.include? payment
      raise ArgumentError.new('This product does not contain payment method')
    end
    self.payment_method_id = payment.id if payment.kind_of?(PaymentMethod)
end

he sees it as redundant. Please tell me how it can be "optimized".

Answer 1

def method=(type, object)
    unless product.shop.send("#{type}_methods").include?(object)
      raise ArgumentError.new('This product does not contain #{type} method')
    end
    self.send("#{type}_method_id}=", object.id) if object.kind_of?("#{type.capitalize}Method".constantize)
end
