[RUBY] Track Rails app errors with Sentry

Agreement

Contract from the following https://sentry.io/signup/

You will create a project at the time of contract, and the setup method is written on the screen after creating the project, so there should be no problem if you proceed according to the procedure. Just in case, I will reorganize it like myself.

Basic usage

`Gemfile`


gem "sentry-raven"

$ bundle install

`config/application.rb`


module AppName
  class Application < Rails::Application
    #abridgement
    Raven.configure do |config|
      config.dsn = "https://#{ENV['SENTRY_KEY']}@#{ENV['SENTRY_SECRET']}.sentry.io/#{ENV['SENTRY_ID']}"
    end
  end
end

In the setup method displayed on the Sentry site, all the IDs etc. are written directly, so I put it in an environment variable.

Be able to pick up parameters and session information

`app/controllers/application.rb`


class ApplicationController < ActionController::Base
  before_action :set_raven_context

  private

  def set_raven_context
    Raven.user_context(id: session[:current_user_id]) # or anything else in session
    Raven.extra_context(params: params.to_unsafe_h, url: request.url)
  end
end

Do not record password in clear text

$ touch config/initializers/sentry.rb

`config/initializers/sentry.rb`


Raven.configure do |config|
  config.sanitize_fields = Rails.application.config.filter_parameters.map(&:to_s)
end

See only errors in production

By default, all development environment errors will be displayed in a list, so correct the settings.
