ExceptionLogger
===============
The Exception Logger (forgive the horrible name) logs your Rails exceptions in the database and provides a funky web interface to manage them.
First you need to generate the migration:
./script/generate exception_migration
Next, you'll need to include the ExceptionLoggable module into ApplicationController. Once that's done you might want to modify key methods to customize the logging:
render_404(exception) - Shows the 404 template.
render_500(exception) - Shows the 500 template.
log_exception(exception) - Logs the actual exception in the database.
rescue_action_in_public(exception) - Does not log these exceptions: ActiveRecord::RecordNotFound, ActionController::UnknownController, ActionController::UnknownAction
Now add a new route to your routes.rb:
map.connect "logged_exceptions/:action/:id", :controller => "logged_exceptions"
After that, visit /logged_exceptions in your application to manage the exceptions.
It's understandable that you may want to require authentication. Add this to your config/environments/production.rb:
# config/environments/production.rb
config.after_initialize do
require 'application' unless Object.const_defined?(:ApplicationController)
LoggedExceptionsController.class_eval do
# set the same session key as the app
session :session_key => '_beast_session_id'
# include any custom auth modules you need
include AuthenticationSystem
before_filter :login_required
# optional, sets the application name for the rss feeds
self.application_name = "Beast"
protected
# only allow admins
# this obviously depends on how your auth system works
def authorized?
current_user.is_a?(Admin)
end
# assume app's login required doesn't use http basic
def login_required_with_basic
respond_to do |accepts|
# alias_method_chain will alias the app's login_required to login_required_without_basic
accepts.html { login_required_without_basic }
# access_denied_with_basic_auth is defined in LoggedExceptionsController
# get_auth_data returns back the user/password pair
accepts.rss do
access_denied_with_basic_auth unless self.current_user = User.authenticate(*get_auth_data)
end
end
end
alias_method_chain :login_required, :basic
end
end
The exact code of course depends on the specific needs of your application.
