Fresh Rails 4.2设置。我想抑制长错误回溯。在下面的回溯日志中,第一行对我来说已足够,接下来的4行可以删除
ActionController::RoutingError (No route matches [GET] "/user"):
actionpack (4.2.1) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'
web-console (2.1.2) lib/web_console/middleware.rb:37:in `call'
actionpack (4.2.1) lib/action_dispatch/middleware/show_exceptions.rb:30:in `call'
railties (4.2.1) lib/rails/rack/logger.rb:38:in `call_app'
我在backtrace_silencers.rb
# config/initializers/backtrace_silencers.rb
Rails.backtrace_cleaner.add_silencer { |line| line =~ /lib/ }
服务器重启后 - 没有任何反应,我仍然得到相同的回溯日志。 (应该删除与/lib/
匹配的每一行:http://api.rubyonrails.org/classes/ActiveSupport/BacktraceCleaner.htm)
完整性检查:
> line = "actionpack (4.2.1) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'"
=> "actionpack (4.2.1) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'"
> line =~ /lib/
=> 19
但过滤器有效:
# config/initializers/backtrace_silencers.rb
Rails.backtrace_cleaner.add_filter { |line| line.gsub('lib', 'yeah!') }
现在回溯看起来像这样:
ActionController::RoutingError (No route matches [GET] "/user"):
actionpack (4.2.1) yeah!/action_dispatch/middleware/debug_exceptions.rb:21:in `call'
web-console (2.1.2) yeah!/web_console/middleware.rb:37:in `call'
actionpack (4.2.1) yeah!/action_dispatch/middleware/show_exceptions.rb:30:in `call'
railties (4.2.1) yeah!/rails/rack/logger.rb:38:in `call_app'
欣赏如何使消音器工作的建议。干杯!

问题在于Minitest-Reporters gem(为Minitest输出添加颜色),它与Rails回溯过滤器混淆
要解决此问题,您需要将以下内容添加到test_helper.rb
Minitest::Reporters.use!(
Minitest::Reporters::DefaultReporter.new,
ENV,
Minitest.backtrace_filter
)

由于application_trace
为空(这是因为错误不是来自用户代码而是路由错误),我们会回退到framework_trace
,它不会过滤它(它只过滤噪音)。< / p>
你可以通过创建自己的log_formatter来达到你的监控。在development.rb
和/或test.rb
添加
config.log_formatter = SilentLogger.new
config.log_formatter.add_silencer { |line| line =~ /lib/ }
在模型中创建只需要方法call
的简单类。在那里,您可以根据需要修改回溯。
class SilentLogger
def initialize
@silencers = []
end
def add_silencer(&block)
@silencers << block
end
def call(severity, timestamp, progname, msg)
backtrace = (String === msg) ? "#{msg}\n" : "#{msg.inspect}\n"
return backtrace if @silencers.empty?
@silencers.each do |s|
backtrace = backtrace.split("\n").delete_if { |line| s.call(line) }
end
backtrace.join("\n")
end
end

在添加自己之前删除默认消音器:
Rails.backtrace_cleaner.remove_silencers!
Rails.backtrace_cleaner.add_silencer { |line| line =~ /lib/ }

我遇到了类似的问题,这是由test_helper中的代码引起的:
def MiniTest.filter_backtrace(backtrace, prefix=nil)
backtrace
end
它被添加到某个阶段和overrides this诊断错误。删除它删除了回溯。
