上面的简短问题，下面的更多细节（大部分是不必要的，但认为它们可能有用）。我对守卫有点陌生，对rails也比较陌生，但是我已经建立了一个运行良好的rails项目，并且守卫正常运行（使用rspec）。主要的是，守卫和自定义记录器都可以完美地工作并且符合他们自己的预期，但是记录器在启用时会打破守卫。

详细信息如下：如果我像这样定义自定义记录器：

logfile = File.open("#{Rails.root}/log/my.log", 'a')
logfile.sync=true
MY_LOGGER = Logger.new(logfile)

在诸如“/lib/assets/my_logger.rb”之类的文件中

如果我在我的 config/development.rb 文件中需要它，如下所示：

require "assets/my_logger"

然后我可以在我的任何控制器中使用这个记录器，但是只要我把它放在那里，例如

class SessionsController < ApplicationController

  def new
  end

  def create
    user = User.find_by(email: params[:session][:email].downcase)
    if user && user.authenticate(params[:session][:password])
      sign_in user
      redirect_back_or user
    else
      flash.now[:error] = 'Invalid email/password combination'
      render 'new'
      MY_LOGGER.info "this will break guard tests"
    end
  end

  def destroy
    sign_out
    redirect_to root_url
  end
end

然后我依赖于控制器中此操作的警卫测试将中断：

（上面注释了 MY_LOGGER 行）：

16:56:33 - INFO - Running: spec/requests/authentication_pages_spec.rb

（为不必要的堆栈跟踪道歉）

现在我一直在看守卫 github 页面，但无法轻易找到任何关于启用我的自定义记录器的任何内容，以便被守卫忽略，有谁知道如何实现这一点？

您需要 logger in config/development.rb，这意味着MY_LOGGER在测试环境中未定义，破坏了您的功能，以便规范正确失败。只需将要求移至config/environment.rb使其在所有环境中可用。
