Integration of Sentry to Rails

Once your Sentry is up and running, let’s look on how to integrate it in your Apps.

As I work on Rails, I am documenting integration of Sentry on Rails App.

Raven for Ruby

sentry-raven is the gem which will act as the client and integration layer for Sentry’s APIs.

gem 'sentry-raven'

Documentation : https://docs.sentry.io/clients/ruby/integrations/rails/

Github project : https://github.com/getsentry/raven-ruby

Configuration inside Project

Adding gem to the Gemfile

Inside your Gemfile, include the sentry-raven gem.

Making a Sentry initializer file.

Make a new file sentry.rb under the rails folder /config/initializers, and save it with following details

Raven.configure do |config|
  config.dsn = '< INSERT DSN key from SENTRY UI -> PROJECT SETTINGS -> Client DSN>'
end

Testing the configuration

Add the following code to any of your methods and check the error on Sentry UI

# inside a method
  Raven.capture do
    # capture any exceptions which happen during execution of this block
    1 / 0
  end

The method containing the above block when called, will result and error and the error should go to Sentry.

Once you receive the line

Sending event XXXXXXXXX to Sentry

Check the Sentry UI whether you received the error entry or not. Sentry is integrated at this point !
