Question

Ruby（2）和Rails（3.2）是否可以在单个命令中更新选择的字段。例如，我需要更新钩子中的一组字段，其中所有名称都匹配。我最终得到了类似的东西

  def set_address
    assign_attributes(address1: subscription.subscriber.address1,
                      address2: subscription.subscriber.address2,
                      address3: subscription.subscriber.address3,
                      city: subscription.subscriber.city,
                      county: subscription.subscriber.county,
                      country_id: subscription.subscriber.country_id,
                      postcode: subscription.subscriber.postcode)
  end

鉴于所有字段名称在两个模型中匹配，有更简单的方法，或者将字段组合在一起以便我可以执行

def set_address
  address = subscription.subscriber.address
end

任何建议表示赞赏

Answer 1

也许是这样的：

[:address1, :address2, :address3, :city, :country, :country_id, :postcode].each do |field|
  send("#{field}=", subscription.subscriber.send(field))
end
