使用ActiveSupport时出现LoadError问题

Question

使用问题时出现load_missing_constant错误。只有我开始rake任务。 Rails服务器/控制台正常启动。

# app/models/journey.rb
class Journey < CouchRest::Model::Base
  include Searchable
end

# app/models/concerns/journey/payable.rb
module Journey::Payable
  extend ActiveSupport::Concern

  module ClassMethods
    def search
      true
    end
  end
end

#application.rb
config.autoload_paths += %W( #{config.root}/lib #{config.root}/app/models/concerns )

错误
