This is the notifier gem for integrating apps with Airbrake.
When an uncaught exception occurs, Airbrake will POST the relevant data to the Airbrake server specified in your environment.

in your ApplicationController, REMOVE this line:
include HoptoadNotifiable
In your config/environment* files, remove all references to HoptoadNotifier
Remove the vendor/plugins/hoptoad_notifier directory.
Remove the vendor/plugins/hoptoad_notifier directory before installing the gem, or run:
script/plugin remove hoptoad_notifier
Add the airbrake gem to your Gemfile. In Gemfile:
gem "airbrake"
Then from your project's RAILS_ROOT, and in your development environment, run:
bundle install
rails generate airbrake --api-key your_key_here
That's it!
The generator creates a file under config/initializers/airbrake.rb configuring Airbrake with your API key. This file should be checked into your version control system so that it is deployed to your staging and production environments.
Add the airbrake gem to your app. In config/environment.rb:
config.gem 'airbrake'
Then from your project's RAILS_ROOT, and in your development environment, run:
rake gems:install
rake gems:unpack GEM=airbrake
script/generate airbrake --api-key your_key_here
As always, if you choose not to vendor the airbrake gem, make sure every server you deploy to has the gem installed or your application won't start.

If you're currently using the plugin version (if you have a vendor/plugins/hoptoad_notifier directory, you are), you'll need to perform a few extra steps when upgrading to the gem version.
Add the airbrake gem to your app. In config/environment.rb:
config.gem 'airbrake'
Remove the plugin:
rm -rf vendor/plugins/hoptoad_notifier
Make sure the following line DOES NOT appear in your ApplicationController file:
include HoptoadNotifier::Catcher
If it does, remove it. The new catcher is automatically included by the gem version of Airbrake.
Before running the airbrake generator, you need to find your project's API key. Log in to your account at airbrake.io, and click on the "Projects" button. Then, find your project in the list, and click on its name. In the left-hand column, you'll see an "Edit this project" button. Click on that to get your project's API key. If you accidentally use your personal API auth_token, you will get API key not found errors, and exceptions will not be stored by the Airbrake service.
Then from your project's RAILS_ROOT, run:
rake gems:install
script/generate airbrake --api-key your_key_here
Once installed, you should vendor the airbrake gem.
rake gems:unpack GEM=airbrake
As always, if you choose not to vendor the airbrake gem, make sure every server you deploy to has the gem installed or your application won't start.
If you're currently using the gem version of the hoptoad_notifier and have a version of Rails that uses config.gem (in the 2.x series), there is a step or two that you need to do to upgrade. First, you need to remove the old version of the gem from vendor/gems:
rm -rf vendor/gems/hoptoad_notifier-X.X.X
Then you must remove the hoptoad_notifier_tasks.rake file from lib:
rm lib/tasks/hoptoad_notifier_tasks.rake
You can then continue to install normally. If you don't remove the rake file, you will be unable to unpack this gem (Rails will think it's part of the framework).
You can test that Airbrake is working in your production environment by using this rake task (from RAILS_ROOT):
rake airbrake:test
If everything is configured properly, that task will send a notice to Airbrake which will be visible immediately.
There is an undocumented dependency in activesupport where the i18n gem is
required only if the core classes extensions are used (active_support/core_ext).
This can lead to a confusing LoadError exception when using Airbrake. Until
this is fixed in activesupport the workaround is to add i18n to the Gemfile
for your Sinatra/Rack/pure ruby application:
gem 'i18n'
gem 'airbrake'
In order to use airbrake in a non-Rails rack app, just load airbrake, configure your API key, and use the Airbrake::Rack middleware:
require 'rack'
require 'airbrake'
Airbrake.configure do |config|
config.api_key = 'my_api_key'
end
app = Rack::Builder.app do
use Airbrake::Rack
run lambda { |env| raise "Rack down" }
end
Using airbrake in a Sinatra app is just like a Rack app:
require 'sinatra'
require 'airbrake'
Airbrake.configure do |config|
config.api_key = 'my api key'
end
use Airbrake::Rack
get '/' do
raise "Sinatra has left the building"
end
For the most part, Airbrake works for itself. Once you've included the notifier in your ApplicationController (which is now done automatically by the gem), all errors will be rescued by the #rescue_action_in_public provided by the gem.
If you want to log arbitrary things which you've rescued yourself from a controller, you can do something like this:
...
rescue => ex
notify_airbrake(ex)
flash[:failure] = 'Encryptions could not be rerouted, try again.'
end
...
The #notify_airbrake call will send the notice over to Airbrake for later
analysis. While in your controllers you use the notify_airbrake method, anywhere
else in your code, use Airbrake.notify.
To perform custom error processing after Airbrake has been notified, define the
instance method #rescue_action_in_public_without_airbrake(exception) in your
controller.
The airbrake gem is capable of telling the user information about the error that just happened via the user_information option. They can give this error number in bug reports, for example. By default, if your 500.html contains the text
<!-- AIRBRAKE ERROR -->
then that comment will be replaced with the text "Airbrake Error [errnum]". You can modify the text
of the informer by setting config.user_information. Airbrake will replace "{{ error_id }}" with the
ID of the error that is returned from Airbrake.
Airbrake.configure do |config| ... config.user_information = "
Tell the devs that it was {{ error_id }}'s fault.
" endYou can also turn the middleware that handles this completely off by setting config.user_information to false.
Paying Airbrake plans support the ability to track deployments of your application in Airbrake. By notifying Airbrake of your application deployments, all errors are resolved when a deploy occurs, so that you'll be notified again about any errors that reoccur after a deployment.
Additionally, it's possible to review the errors in Airbrake that occurred before and after a deploy.
When Airbrake is installed as a gem, you need to add
require 'airbrake/capistrano'
to your deploy.rb
If you don't use Capistrano, then you can use the following rake task from your deployment process to notify Airbrake:
rake airbrake:deploy TO=#{rails_env} REVISION=#{current_revision} REPO=#{repository} USER=#{local_user}
You can also pass a hash to Airbrake.notify method and store whatever you want,
not just an exception. And you can also use it anywhere, not just in
controllers:
begin
params = {
# params that you pass to a method that can throw an exception
}
my_unpredicable_method(params)
rescue => e
Airbrake.notify(
:error_class => "Special Error",
:error_message => "Special Error: #{e.message}",
:parameters => params
)
end
While in your controllers you use the notify_airbrake method, anywhere else in
your code, use Airbrake.notify. Airbrake will get all the information
about the error itself. As for a hash, these are the keys you should pass:
:error_class- Use this to group similar errors together. When Airbrake catches an exception it sends the class name of that exception object.:error_message- This is the title of the error you see in the errors list. For exceptions it is "#{exception.class.name}: #{exception.message}":parameters- While there are several ways to send additional data to Airbrake, passing a Hash as :parameters as in the example above is the most common use case. When Airbrake catches an exception in a controller, the actual HTTP client request parameters are sent using this key.
Airbrake merges the hash you pass with these default options:
{
:api_key => Airbrake.api_key,
:error_message => 'Notification',
:backtrace => caller,
:parameters => {},
:session => {}
}
You can override any of those parameters.
One common request we see is to send shell environment variables along with manual exception notification. We recommend sending them along with CGI data or Rack environment (:cgi_data or :rack_env keys, respectively.)
See Airbrake::Notice#initialize in lib/airbrake/notice.rb for more details.
You can specify a whitelist of errors that Airbrake will not report on. Use this feature when you are so apathetic to certain errors that you don't want them even logged.
This filter will only be applied to automatic notifications, not manual notifications (when #notify is called directly).
Airbrake ignores the following exceptions by default:
AbstractController::ActionNotFound
ActiveRecord::RecordNotFound
ActionController::RoutingError
ActionController::InvalidAuthenticityToken
ActionController::UnknownAction
CGI::Session::CookieStore::TamperedWithCookie
To ignore errors in addition to those, specify their names in your Airbrake configuration block.
Airbrake.configure do |config|
config.api_key = '1234567890abcdef'
config.ignore << "ActiveRecord::IgnoreThisError"
end
To ignore only certain errors (and override the defaults), use the #ignore_only attribute.
Airbrake.configure do |config|
config.api_key = '1234567890abcdef'
config.ignore_only = ["ActiveRecord::IgnoreThisError"] # or [] to ignore no exceptions.
end
To ignore certain user agents, add in the #ignore_user_agent attribute as a string or regexp:
Airbrake.configure do |config|
config.api_key = '1234567890abcdef'
config.ignore_user_agent << /Ignored/
config.ignore_user_agent << 'IgnoredUserAgent'
end
To ignore exceptions based on other conditions, use #ignore_by_filter:
Airbrake.configure do |config|
config.api_key = '1234567890abcdef'
config.ignore_by_filter do |exception_data|
true if exception_data[:error_class] == "RuntimeError"
end
end
To replace sensitive information sent to the Airbrake service with [FILTERED] use #params_filters:
Airbrake.configure do |config|
config.api_key = '1234567890abcdef'
config.params_filters << "credit_card_number"
end
Note that, when rescuing exceptions within an ActionController method, airbrake will reuse filters specified by #filter_parameter_logging.
When you run your tests, you might notice that the Airbrake service is recording notices generated using #notify when you don't expect it to. You can use code like this in your test_helper.rb or spec_helper.rb files to redefine that method so those errors are not reported while running tests.
module Airbrake
def self.notify(thing)
# do nothing.
end
end
The notifier supports using a proxy, if your server is not able to directly reach the Airbrake servers. To configure the proxy settings, added the following information to your Airbrake configuration block.
Airbrake.configure do |config|
config.proxy_host = proxy.host.com
config.proxy_port = 4038
config.proxy_user = foo # optional
config.proxy_pass = bar # optional
See SUPPORTED_RAILS_VERSIONS for a list of official supported versions of Rails.
Please open up a support ticket ( http://help.airbrake.io ) if you're using a version of Rails that is listed above and the notifier is not working properly.
To automatically include the Javascript node on every page, use this helper method from your layouts:
<%= airbrake_javascript_notifier %>
It's important to insert this very high in the markup, above all other javascript. Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf8">
<%= airbrake_javascript_notifier %>
<!-- more javascript -->
</head>
<body>
...
</body>
</html>
This helper will automatically use the API key, host, and port specified in the configuration.
To test the Javascript notifier in development environment, overwrite (temporarily) the development_environments option:
Airbrake.configure do |config|
# ...
config.development_environments = []
end
See TESTING.md for instructions on how to run the tests.
