I find ignoring exceptions is a common need, and ExceptionNotifier supports the excellent ignore_exceptions option for this but there is very little documentation on it. One must go to the source code to find out how it works. I would love to see a section in the readme dedicated to this option and also mentioning which sections are ignored by default.

This might be helpful when correlating emails with the logfile.

Got an issue with exceptions:

The ignore_if options is a good start, but it could give env as a parameter

https://github.com/smartinez87/exception_notification/blob/master/lib/exception_notifier.rb#L30

@options[:ignore_if]         ||= lambda { |env, e| false }

unless ignored_exception(options[:ignore_exceptions], exception)       ||
           from_crawler(options[:ignore_crawlers], env['HTTP_USER_AGENT']) ||

           options[:ignore_if].call(env, exception)   # < THIS LINE ALSO

      Notifier.exception_notification(env, exception).deliver
      env['exception_notifier.delivered'] = true
end

For us the mailing probability game. I would like to have custom rules like "If no session cookie in request and if user_agent not recognized". This so that we receive exception notifies in most cases but not with new unrecognized bots etc.

In addition to this the ignore_if could be wrapped so that errors inside lambda would not affect. I'm not sure if this should be implemented or left to user. I'm just afraid that when lambda crashes you will lose the exception info and get no email.

ignored_if(options[:ignore_if].call(env, exception))

# wrapper so that if users lambda is errorous it will return true
def ignored_if(lamb, env, exception)
  return lamb.call(env, exception)
rescue Exception => e
  true
end

Hey, just a quick heads up for 3.1 support. It is working, but due to activesupport ~> 3.0.9 being added to the Gemfile I can't use it anymore. Maybe you could loose the dependency to >= 3.0.9?

Hello,

Thanks for all the work you are doing with the exception_notification plugin. It's simple to setup and just works!

I'm using Rails 3.1.3 and have a Mailer already set up and working to deliver various emails. It is configured in an initialiser that looks something like:
https://gist.github.com/1610899#file_email_setup.rb

The app uses another initialiser to setup exception_notification. I got the idea from:
http://stackoverflow.com/a/5490583

On running exception_notification, exceptions get mailed with the settings from the default Mailer. Is it possible to create a separate configuration just for exception_notification to use? If, so how?

Thanks in advance!

I'm getting an error when trying to send a background exception notification for delayed job. It appears the email view does not have a valid exception object, but I used a debugger and the exception passed was valid (and responded to message). Any idea what could be causing this?

After watching Railscast, I implemented exception_notifier on new Rails project. When I tested ignoring specified exceptions these exceptions were not ignored. And when I mean not ignored I continued to get mail (via letter_opener).

I see from the Readme that the license is MIT, but there is no LICENSE file in the root of the project. Would be good to add that just to be safe.

I placed the code as suggested in config.ru and it does nothing. Not mail is sent. Can someone provide a sample of a config.ru that does work properly?

Using rails 3.09

Sebastian,

I had a problem porting an app to Rails 3.0 using exception_notification. It didn't seem to be able to find my custom section partial (called "user").

When I changed exception_notification.text.erb as follows, it worked:

<%  sections = @sections.map do |section|
      if section == 'user'
        summary = render('exception_notifier/user').strip
      else
        summary = render(section).strip
      end
      unless summary.blank?
        title = render("title", :title => section).strip
        "#{title}\n\n#{summary.gsub(/^/, "  ")}\n\n"
      end
    end %>

IOW, it looks like it needed the exception_notifier prefix. I'm guessing that I just missed something somewhere. Is this a real issue or am I crazy?

Thanks,

Steve

I presume ExceptionNotifier::Notifier.exception_notification(request.env, exception) would not work in rake tasks since there is no request.env.

What can we pass into the notifier if there is no request.

The ignore_exceptions option is great, but it's only possible to ignore exceptions based on their class. It would be nice if exceptions could be ignored conditionally. Perhaps there could be an option for this where a lambda could be passed in? This could pass information about the current request and the exception.

Great work on the gem.

I have both the exception_notification and vidibus-routing_error gems installed. They work fine individually, but exception_notification doesn't work with vidibus-routing_error enabled.

vidibus-routing_error requires the following code to be added to your application_controller.rb:

if Rails.env.production?
  rescue_from Exception, :with => :render_500
  rescue_from ActionController::RoutingError, :with => :render_404
  rescue_from ActionController::UnknownAction, :with => :render_404
  rescue_from ActiveRecord::RecordNotFound, :with => :render_404
end

private

def render_404
  render "shared/404", :status => 404
end

def render_500
  render "shared/500", :status => 500
end

Since the default Rails exception handling is already preempted by this code, is there a way to call exception_notification from within those two custom actions?

Hi there,

I noticed you are the new maintainer of exception_notification. I was wondering if you could release a gem with the current state of the code. Currently there is no gem available.

It would be highly appreciated.

Thanks!

lib/exception_notifier/notifier.rb#clean_backtrace: some exceptions won't have a backtrace, i.e. if an exception object is created. Looks like the background_exception_notification method handles no backtrace, but not exception_notification.

If by default ActiveRecord::RecordNotFound is in the default_ignore_exceptions, why am I getting emails for them?

Also, how to add more exceptions to the default_ignore_exceptions?

fesplugas reported the following:

With the current published gem something like:

gem 'exception_notification'

Doesn't work. You need to do a explicit require:

gem 'exception_notification', :require => 'exception_notifier'

Can be this be fixed?

Noticing now that background exceptions don't have the time.

Should there be a "system" section that would have this for both normal and background exceptions, and maybe for other data as well?

Hi — thanks for reviving this project!

So I'm potentially migrating away from Exceptional, which has Exceptional::Catcher.handle_with_controller and Exceptional.handle, which are analogs to ExceptionNotifier::Notifier.exception_notification and ExceptionNotifier::Notifier.background_exception_notification.

a few things about ExceptionNotifier::Notifier.background_exception_notification

1. it's sort of a second class citizen — it doesn't allow for custom templates
2. it has repeated code from ExceptionNotifier::Notifier.exception_notification
3. it's the only thing that can be appropriately used in a model (right?), so it's sort of misnamed

Maybe I'm wrong on 3, and I should just be using ExceptionNotifier::Notifier.exception_notification with an empty environment hash?

Let me know what you think — I'd be interested in cleaning it up, so that there is some sort of common method that is called in all contexts, doesn't repeat code, and reuses the templates.

Hey,

Isn't it possible to set the server or sendmail delivery options?

Thank you

Switched back to 2.4.1 for now.

Recent updates (e.g. :verbose_subject option) were committed after the most recent exception_notification.gemspec version bump to 2.5.2.

I'm installing with:

gem "exception_notification"

... but I do not get the latest version. I can see in the source that the gemspec says it's 2.5.2 but the code is not up to date with the most recent commits.

Please excuse if this is normal operation between version bumps, but I find it confusing that online version is not equal to what bundler retrieves for the same gemspec version.

The links on http://rubygems.org/gems/exception_notification still go to https://github.com/rails/exception_notification.

Simply adding this gem to my gemfile triggers

OpenSSL::SSL::SSLError (SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: unknown protocol)

error every time ANY email is sent. Removing this gem allows mail delivery to return to normal...

I'm using rails (3.0.11) and actionmailer (= 3.0.11)

Please ask the Rails team to use GitHub's Transfer Ownership feature (in the Admin interface for the repository on GitHub) and give control of the official rails/exception_notification repository to you.

It took me a while to figure out that the official one was deprecated and that yours was to be treated as the official one from now on --- really? a little note in the GitHub repository description... very hard to overlook!

Thanks. 👮

I'm getting emails for ActiveRecord::RecordNotFound messages:

My configuration:

And I get emails for Page not found:

A ActiveRecord::RecordNotFound occurred in stories#show:

Couldn't find Story with id=christian_test

This is a Rails 3.2.2 application at: http://github.com/docwhat/chicagoiands

Am I reading the docs wrong? I thought that it should ignore those by default.

It would be nice to have a way to set a limit on how many emails can be sent in a defined time period or of error type. I recently had a situation where an error was being thrown in a loop and got hundreds of emails.

Try running

ExceptionNotifier::Notifier.background_exception_notification e

when you haven't got the middleware enabled.

There is a check in the code to see if the middleware is enabled, but ActionMailer will just try to deliver anyway.

I tried to fix by raising + rescuing a custom error but couldn't fix it :(

No exception_notifier.options in request.env, I have to set it manually.
I have to do something like that:

def log_error(exception)
if notifier = Rails.application.config.middleware.detect { |x| x.klass == ExceptionNotifier }
env = request.env
env['exception_notifier.options'] = notifier.args.first || {}
ExceptionNotifier::Notifier.exception_notification(env, exception).deliver
env['exception_notifier.delivered'] = true
end
end

Hi,
I am using the 2.5.2 version of the gem, but I want to have mails for all the exceptions I can have. I could not find how to remove the default ignored exceptions, as RoutingError for example.
How can we do that ?
Thanks,
Alex

Hello,

I am using Mailgun, and I would like to be able to set a header for my exception emails:

X-Mailgun-Track: no

This is useful because usually I would like mailgun to rewrite my urls for tracking, but for exception notifications I do not want them rewritten. Is there a way for me to configure this with ExceptionNotification?

I'm using exception_notification 2.5.2 and getting an exception when I try to call background_exception_notification with 2 arguments (exception and data), as described in the readme.

Looking at the gem code I have, the method is def background_exception_notification(exception), but in github, the latest method is def background_exception_notification(exception, options={}).

Is this a recent change not in 2.5.2 code ?

Running 2.6.1 works great in development & production mode locally but kills the live server dead with the below error in my Unicorn log.

unicorn:23:in

I've tried the "require => exception_notifier" option and a few other classics from stackoverflow but still no luck. Have tried as middleware in config.ru and in production.rb, same error for both.

This may well be my fault but I'm not sure how to diagnose it any deeper than the options I've tried and I can't find any major differences between my live and local configs.

the pre-middleware-version had an option (consider_local) to set ip addresses which should not trigger notifier but show exception as in development mode:

class ApplicationController < ActionController::Base
include ExceptionNotifiable

ips = %w[127.0.0.1 192.168.0.1 192.168.0.2 192.168.0.3]
consider_local(*ips)
end

is there any other middleware or workaround to achieve this with the current version?

If someone submits a password in a form, and an error triggers exception_notification, the password is shown in plain-text under "action_controller.request.request_parameters", "rack.request.form_hash", and "rack.request.form_vars" (even though params is filtered properly). Using Rails 2.3.

From delayed job instructions:

Due to how mailers are implemented in Rails 3, we had to do a little work around to get delayed_job to work.

without delayed_job

Notifier.signup(@user).deliver

with delayed_job

Notifier.delay.signup(@user)
Remove the .deliver method to make it work. It’s not ideal, but it’s the best we could do for now.

The method that sends the background_notification is using the deliver option. See:

mail(:to => @options[:exception_recipients], :from => @options[:sender_address], :subject => subject) do |format|
format.text { render "#{mailer_name}/background_exception_notification" }
end.deliver

This method should be written using 'delay' instead of deliver to make it work with delayed_job.

Instead we get this:

wrong number of arguments (2 for 1)
/Users/kain/.rvm/gems/ruby-1.9.3-p0/gems/exception_notification-2.5.2/lib/exception_notifier/notifier.rb:70:in `background_exception_notification'

I found that a certain path through my Rails code was triggering an ActionDispatch::Cookies::CookieOverflow. Unfortunately exception_notification did not email me (I only found out when I received a phone call from a customer).

Can we get this exception_notification to handle this error?

now the custom error pages work fine, but no mail sent when exception generated.
After debugging the app, i found the def call (env) method in exception_notification.rb doesn't excute the code below after @app.call(env)
rescue Exception => exception
options = (env['exception_notifier.options'] ||= {})
options.reverse_merge!(@options)

unless Array.wrap(options[:ignore_exceptions]).include?(exception.class)
  Notifier.exception_notification(env, exception).deliver
  env['exception_notifier.delivered'] = true
end

raise exception

end
But exception_notification works fine without the codes for custom dynamic error pages in application_controller.rb.
So i wanna know if there is a solution works with exception_notification and custom error pages in rails3. rescue_action_in_public is now as a middleware in actiondispath showexceptions and can't overwrite it in application_controller.rb

Using version 2.6.0 with rails 3.2.2, ruby 1.8.7.

Finally started using the background_exception_notification section and ran into an error where it looks like my custom section is not being found..
I am using my own custom section (from environment.rb):

      :sections => %w{instructions_for_support} + ExceptionNotifier::Notifier.default_sections,
      :background_sections => %w{instructions_for_support} + ExceptionNotifier::Notifier.default_background_sections
  }

(other parts are set elsewhere).

The instructions_for_support partial is being found just fine when I use the exception_notifier method, but it's not finding it when I use background_exception_notification. To investigate I renamed the partial so it wouldn't be found.

With exception_notification I get this message:

Missing partial exception_notifier/instructions_for_support with {:formats=>[:text], :locale=>[:en], :handlers=>[:coffee, :erb, :builder]}. Searched in:
    * "/home/bselig/.rvm/gems/ruby-1.8.7-p334@Upgrade32/gems/exception_notification-2.6.0/lib/exception_notifier/views"
    * "/mnt/dev_shared_codebase/Upgrade_Rails_32x/app/views"

and with background_exception_notification I get this error:

Missing partial exception_notifier/instructions_for_support with {:formats=>[:text], :locale=>[:en], :handlers=>[:coffee, :erb, :builder]}. Searched in:
  * "/home/bselig/.rvm/gems/ruby-1.8.7-p334@Upgrade32/gems/exception_notification-2.6.0/lib/exception_notifier/views"

As you can see, exception_notification is searching in my app's views folder while background_exception_notification is not.
The difference seems to be this line:

      self.append_view_path Rails.root.nil? ? "app/views" : "#{Rails.root}/app/views" if defined?(Rails)

which is at the beginning of exception_notification but not background_exception_notification.

Am I misunderstanding something or is this just an oversight in the code?

This guy explains the issue nicely: http://stackoverflow.com/questions/5389754/custom-partials-in-exception-notification-in-rails-3

But basically, the view path for the gem seems to be specific to the gem's location and does not consult the app's view path. Is there any help for this or am I just doing it wrong perhaps?

I tried adding a section called highlights to options[:sections] and started receiving the error:

Missing partial exception_notifier/highlights with {:locale=>[:en], :handlers=>[:rjs, :rhtml, :rxml, :erb, :builder], :formats=>[:text]} in view paths "C:/Ruby187/lib/ruby/gems/1.8/gems/exception_notification-2.4.0/lib/exception_notifier/views"

Thanks

I'm using Rails-3.0.6 and exception_notification-2.4.0. I've configured Rails for sendmail:

config.action_mailer.delivery_method = :sendmail

My sendmail replacement is Exim4, the lastest Ubuntu/Debian package. When there is an exception, an email is sent, but it is an error message from Exim:

A message that you sent using the -t command line option contained no
addresses that were not also on the command line, and were therefore
suppressed. This left no recipient addresses, and so no delivery could
be attempted.

------ This is a copy of your message, including all the headers. ------
{{snip}}

Is it possible that Exim is too strict and something is missing?

Thanks,
Michael

Using Rails 3.0.9, all the exception notifications we get seem to be missing most of the session data. Is this a consequence of exception_notification moving down to the middleware level and not seeing the Rails-specific stuff? Example session partial:

session id: nil

• data: {"_csrf_token"=>"some_stuff",
  "warden.user.user.key"=>["User", [10618], "some_stuff"]}

The session ID should be filtered, particularly for secure requests.

Rails 3.2.1

Gemfile

gem 'exception_notification', :git => 'git://github.com/smartinez87/exception_notification.git'

Config.ru

Blah::Application.config.middleware.use ExceptionNotifier,
:email_prefix => '[Blah] ',
:sender_address => '"Blah" [email protected]',
:exception_recipients => ['[email protected]']

Trying to test if exception notifier is working at all from the rails console:

ExceptionNotifier::Notifier.exception_notification({}, Exception.new("exception message"), :data => {:message => "was doing something wrong"}).deliver

sendmail: fatal: [email protected](501): No recipient addresses found in message header
postdrop: warning: stdin: unexpected EOF in data, record type 78 length 116
postdrop: fatal: uid=501: malformed input
=> #<Mail::Message:2170288820, Multipart: false, Headers: <Date: Thu, 07 Jun 2012 17:47:06 -0300>, <From: "Exception Notifier" [email protected]>, <To: >, <Message-ID: [email protected]>, <Subject: [ERROR] # (Exception) "exception message">, <Mime-Version: 1.0>, <Content-Type: text/plain>, <Content-Transfer-Encoding: 7bit>>

It would be a great if exception_notification can be configured when mail body contains some readable for common users text (something like "We're sorry, but there's error on page bla-bla-bla."), and full bug report is attached as text file.
