Rails + bunny gem - 没有要加载的文件 - bunny

Question

我有一个 Rails 控制器：

class Console::AccesorBillsController < ConsoleController
  ...
  def bill
    AcceccorBill.new.run

    render :nothing => true
  end
end

我在那里创建新模型并使用兔子页面 (http://rubybunny.info/articles/getting_started.html) 中的示例运行方法：

require "bunny"

class AcceccorBill
  def initialize()
  end

  def run
    conn = Bunny.new
    conn.start

    ch  = conn.create_channel
    x   = ch.fanout("nba.scores")

    ch.queue("joe",   :auto_delete => true).bind(x).subscribe do |delivery_info, metadata, payload|
      puts "#{payload} => joe"
    end

    ch.queue("aaron", :auto_delete => true).bind(x).subscribe do |delivery_info, metadata, payload|
      puts "#{payload} => aaron"
    end

    ch.queue("bob",   :auto_delete => true).bind(x).subscribe do |delivery_info, metadata, payload|
      puts "#{payload} => bob"
    end

    x.publish("BOS 101, NYK 89").publish("ORL 85, ALT 88")

    conn.close
  end
end

但我总是得到这个错误：

NameError - uninitialized constant AcceccorBill::Bunny:
  (gem) activesupport-3.1.12/lib/active_support/dependencies.rb:507:in `load_missing_constant'
  (gem) activesupport-3.1.12/lib/active_support/dependencies.rb:181:in `block in const_missing'

  (gem) actionpack-3.1.12/lib/action_controller/metal/rendering.rb:10:in `process_action'

有人知道怎么解决吗？

P.S.：我通过 bundler 安装了 gem，看起来 require 不起作用。

Answer 1

解决了。

我忘了要求bundler。所以我只是在文件的开头添加了这个：

require "bundler/setup"
require "bunny"

仅此而已。
