lib/下我有'aisis_writer / loader.rb',在该文件中,它看起来像:

module AisisWriter
  module Loader
  end
end

然后我在我的application.rb以下设置:

require File.expand_path('../boot', __FILE__)

# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)

module AisisWriter
  class Application < Rails::Application
    # Load Lib
    config.autoload_paths += %W(#{config.root}/lib)

    # Use Rack Attack For Throttling
    config.middleware.use Rack::Attack
  end
end

从那里我做了ApplicationController.rbinclude AisisWriter::Loader,然后我运行了测试并得到了:

'<class:ApplicationController>': uninitialized constant AisisWriter::Loader (NameError)

由于命名冲突或我做错了,我无法做我正在做的事情。任何人都想告诉我,我可能做错了什么?

我认为你的config.autoload_paths不够广泛 - 它不包括lib目录的子文件。

这应该可以解决问题:

config.autoload_paths += Dir[Rails.root.join('lib', '{**/}')]

答案 1 :(得分:-1)

在&#39; aisis_writer / loader.rb&#39;

中尝试这样定义
module AisisWriter::Loader
end
