Exception Logger for Rails

Store the error logs of your rails application directly in the application's database. Just a quick way to monitor error logs without the need for additional tools.

Install

Inside your Gemfile:

gem 'exception_logger'

and then run:

bundle install

Inside your ApplicationController:

include ExceptionLogger::ExceptionLoggable # load the module
rescue_from Exception, with: :log_exception_handler # tells rails to forward the 'Exception' (you can change the type) to the handler of the module

Inside your config/routes.rb

mount ExceptionLogger::Engine => "/exception_logger"

Database Setup

Use

rails exception_logger:install:migrations

This will create a database migration inside db/migrations

TIMESTAMP_create_exception_logger_logged_exceptions.exception_logger.rb

Then

rails db:migrate

Authentication

If you want, and believe me you want that, you can add the following lines in config/initializers/exception_logger.rb to enable Authentication:

Rails.application.config.after_initialize do
  ExceptionLogger::LoggedExceptionsController.class_eval do
    before_filter :authorize

    protected

    def authorize
      redirect_to main_app.admin_login_path unless admin_logged?
    end

    def admin_logged?
      session[:admin_user_id].present?
    end
  end
end

Usage

To localize the interface:

en:
  exception_logger:
    logged_exceptions:
      index:
        title: Logged Exceptions
        filters: Filters
        latest_exceptions: Latest Exceptions
        exception: Exception
        controller_action: Controller / Action
        dates: Dates
        today: Today
        last_few_days: Last few days
        last_7_days: Last 7 days
        last_30_days: Last 30 days
      show:
        title: Logged Exception

To log extra data, in your ApplicationController:

self.exception_data = Proc.new { |controller| 'Extra exception infomation here!' }

self.exception_data = :extra_exception_data

def extra_exception_data
  'Extra exception infomation here!'
end
