隐藏所有异常消息

我正在运行Rails 3.0.8,Webrick webserver在生产模式下启动了这样的命令

RAILS_ENV=production rails server

我有以下问题。

我已经读过,生产模式下的rails应该处理所有异常和错误。 但是当我试图在生产模式下获取未发现的项目时,我实际上仍然有错误消息“ActiveRecord :: RecordNotFound”。

我也读到了

rescue_from ActiveRecord::RecordNotFound, :with => :page_not_found

这样的黑客,但我认为它不是Rails方式。

这是我的production.rb文件内容:

BeerPub::Application.configure do
  # Settings specified here will take precedence over those in config/application.rb

  # The production environment is meant for finished, "live" apps.
  # Code is not reloaded between requests
  config.cache_classes = true
  config.whiny_nils = false

  # Full error reports are disabled and caching is turned on
  config.consider_all_requests_local       = false
  config.action_view.debug_rjs             = false
  config.action_controller.perform_caching = true

  # Specifies the header that your server uses for sending files
  config.action_dispatch.x_sendfile_header = "X-Sendfile"

  # For nginx:
  # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect'

  # If you have no front-end server that supports something like X-Sendfile,
  # just comment this out and Rails will serve the files

  # See everything in the log (default is :info)
  # config.log_level = :debug

  # Use a different logger for distributed setups
  # config.logger = SyslogLogger.new

  # Use a different cache store in production
  # config.cache_store = :mem_cache_store

  # Disable Rails's static asset server
  # In production, Apache or nginx will already do this
  config.serve_static_assets = true

  # Enable serving of images, stylesheets, and javascripts from an asset server
  # config.action_controller.asset_host = "http://assets.example.com"

  # Disable delivery errors, bad email addresses will be ignored
  # config.action_mailer.raise_delivery_errors = false

  # Enable threaded mode
  # config.threadsafe!

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation can not be found)
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners
  config.active_support.deprecation = :notify
end

正如你所看到的,这很常见。

请帮我解决这个问题。

UPD:

我也会收到以下错误

Routing Error

No route matches "/lol"

这是另一种例外,但问题是一样的。处理这种情况的最佳方法是什么?

“我已经读过,生产模式下的rails应该处理所有异常和错误。”

这是不正确的,Rails本身不会捕获异常,但只是在生产模式下你有不同的方法来处理它们。

你写的rescue_from方法绝对正确。

许多Rails开发人员并不关心如何挽救RecordNotFound异常,因为根据应用程序的不同,用户做错了什么。

然而,有些应用程序喜欢捕获此异常并执行自定义操作,例如重定向,渲染文本或不同视图。
