禁用 Rubocop 关于方法的投诉

Question

我有一个像这样的方法 return if amount == 0 而 rubocop 抱怨它应该像 return if amount.zero?。我怎样才能让它跳过那个方法？这是我的 .rubocop.yml:

rubocop

    - spec/rails_helper.rb
    - spec/teaspoon_env.rb

  TargetRubyVersion: 2.3

Rails:
  Enabled: true

submit_ticket_payment.rb

def call
  return if amount == 0
  Stripe::Charge.create(
    amount: amount,
    currency: "usd",
    description: event_name,
    receipt_email: context.rsvp.email,
    source: context.token,
    statement_descriptor: event_name
  )
rescue Stripe::StripeError
  context.fail!
end

所以基本上我怎么能让它不关心那个特定的实例？

Answer 1

如果您只想跳过此特定方法的规则，则：

# rubocop:disable Style/NumericPredicate
def call
  return if amount == 0
  # ...
end
# rubocop:enable Style/NumericPredicate

Answer 2

有问题的检查由 Style/NumericPredicate 警察执行。

如果您一般希望启用它但不抱怨个别事件，您可以通过特殊注释暂时禁用它：

# rubocop:disable Style/NumericPredicate
return if amount == 0
# rubocop:enable Style/NumericPredicate

注意需要重新启用；否则它将跳过对整个文件剩余部分的检查。
