Ruby on rails 我的应用程序中未定义的方法。发生了什么？

我试着像这样阻止我的应用程序中的Ip地址-。我在/lib和model\u ip中已经有了一个模块

为什么我在下面的views/banked_ips/index.html中出现此错误

==我的错误：===

管理/禁止索引中的命名错误

显示app/views/admin/banked_ips/index.html.erb，其中第9行出现：

第9行附近的提取源：

==模块infrid.rb在/lib中===

module Infrid
  class IPAddress
    include Comparable
    def initialize(address)
      @address = address
    end
    def split
      @address.split(‘.‘).map {|s| s.to_i }
    end
    def <=>(other)
      split <=> other.split
    end
    def to_s
      @address
    end
  end
end

===禁用的型号\u ip：===

class BannedIp < ActiveRecord::Base
    @banned_ips # hash of ips and masks
    validates_presence_of :first_ip, :message =>"first address is needed"
    validates_presence_of :last_ip, :message =>"last address is needed"
    validates_format_of :first_ip, :with => REG_IP, :message => "is invalid (must be x.x.x.x where x is 0-255)", :if => Proc.new {|ar| !ar.first_ip.blank? }
    validates_format_of :last_ip, :with => REG_IP, :message => "is invalid (must be x.x.x.x where x is 0-255)", :if => Proc.new {|ar| !ar.last_ip.blank? }

    def self.banned?(ip)
      reload_banned_ips if @banned_ips.nil?
      begin
          ip = Infrid::IPAddress.new(ip)
          @banned_ips.each { |b|
            return true if ip.between?(b[0], b[1])
          }
      rescue
          logger.info "IP FORMAT ERROR"
          return true
      end
      false
    end
    def self.banned_ips
        reload_banned_ips if @banned_ips.nil?
        @banned_ips.collect {|b| b[0].to_s + ".." + b[1].to_s }.join"\n"
    end
    #keeps a cache of all banned ip ranges
    def self.reload_banned_ips
      r = connection.select_all("select first_ip, last_ip from banned_ips")
      if !r
        @banned_ips=[] 
      end
      @banned_ips = r.map {|item| [Infrid::IPAddress.new(item["first_ip"]),Infrid::IPAddress.new(item["last_ip"])] }
    end
end

该request.remote_ip以字符串形式返回ip地址，并且字符串没有禁用的？方法看起来您想要BannedIP.Banding？request.remote_ip。

您的问题是您试图呼叫banned？在绳子上，而不是在你的课堂上。你有两个解决方案

将用于检查禁用ip的代码替换为banndip.banding？request.remote_ip 将一个方法修补到string类，该类为您调用class方法，该方法在rails stype中，但可读性较差。 我需要这个。错误阻止代码块工作

class String
  def banned?
    BannedIp.banned?(self)
  end
end

请尝试，返回此错误：预期D:/IR/rails_apps/cinemato/app/models/banned_ip.rb来定义BannedIP文件是否实际位于该位置？谢谢，BannedIP.banned？request.remote_ip在使用“ip”而不是“ip”写入BannedIP时有效。谢谢，BannedIP.banned？request.remote_ip在使用“ip”写入BannedIP时有效。
