This snippet explains how to install and use the Rails exception_logger plugin. I'll also show you how to protect your logs by extending the plugin with basic authentication.
script/plugin source http://svn.techno-weenie.net/projects/plugins script/plugin install exception_logger
I'm using Rails Edge on this project, so I had to install classic pagination also:
script/plugin install svn://errtheblog.com/svn/plugins/classic_pagination
Next create and execute the migration file:
./script/generate exception_migration rake db:migrate
Before starting the server we need to setup the routes:
map.exceptions '/logged_exceptions/:action/:id', :controller => 'logged_exceptions', :action => 'index', :id => nil
You also need to include the ExceptionLoggable in your ApplicationController:
class ApplicationController < ActionController::Base include ExceptionLoggable ...
Start your server and access the exception log at /logged_exceptions.
Exceptions can contain email addresses, passwords, credit card numbers, so you'll want to protect /logged_exceptions from the public. This can be done by adding the following code to the end of environment.rb:
config.after_initialize do require 'application' unless Object.const_defined?(:ApplicationController) LoggedExceptionsController.class_eval do before_filter :authenticate protected def authenticate authenticate_or_request_with_http_basic do |username, password| username == "foo" && password == "bar" end end end end
With this code we add a before filter that shows a login dialog to anyone trying to access /logged_exception/. Note that this requires Rails 2.0 basic authentication to work, so make sure you have the proper version installed.
