Question

我创建了一个在我的生产环境中无效的自定义验证器/关注点。它适用于我的单元测试和我的开发（localhost）环境。

用户可以在UI中提交一些IP地址（以逗号分隔），然后传递给我关注：

因此，类似192.168.1.1-10,192.168.1.0/24,10.10.10.1的内容会被发送到模型：

class Device < ApplicationRecord
  validates :ips_scan, :ips_exclude, ip: true, on: :update
end

在我的concerns文件夹中有一个名为ip_validator.rb的文件：

class IpValidator < ActiveModel::Validator
  def validate(record)
    if record.ips_scan
      ips = record.ips_scan.split(',')
      ips.each do |ip|
        /([0-9]{1,3}\.){3}[0-9]{1,3}(\/([1-2][0-9]|[0-9]|3[0-2]))?(-([0-9]{1,3}))?/ =~ ip
        puts ip
        record.errors.add(:ips_scan, 'is not valid') unless $LAST_MATCH_INFO
      end
    end

    if record.ips_exclude
      ips = record.ips_exclude.split(',')
      ips.each do |ip|
        /([0-9]{1,3}\.){3}[0-9]{1,3}(\/([1-2][0-9]|[0-9]|3[0-2]))?(-([0-9]{1,3}))?/ =~ ip
        record.errors.add(:ips_exclude, 'is not valid') unless $LAST_MATCH_INFO
      end
    end
  end
end

Device控制器是：

class DevicesController < ApplicationController
  before_action :set_device, only: %i[edit show update]
  respond_to :html

  def show; end

  def edit; end

  def update
    if @device.update(device_params)
      flash[:notice] = 'Successful update'
      redirect_to request.referrer
    else
      flash[:warning] = 'Address formats allowed: x.x.x.x OR x.x.x.x-x OR x.x.x.x/x'
      redirect_to request.referrer
    end
  end

  private def set_device
    @device = Device.find(params[:id])
  end

  private def device_params
    params.require(:device).permit(:token, :nickname, :ips_scan, :ips_exclude, :status)
  end
end

正如我所提到的，这在开发中有效，但生产中的日志只是在尝试更新时回滚：

I, [2018-04-28T13:09:02.478701 #1]  INFO -- : Started PUT "/devices/2" for XX.XX.XXX.XX at 2018-04-28 13:09:02 +0000

我错过了什么？

Rails IP验证器无法在生产环境中工作
