getting ActiveRecord::RecordNotFound emails about exception_notification

[jaredhoward]

This is actually my issue; I accidentally used the wrong account to start this issue.

Looking into this a little farther, I'm noticing that ActiveRecord::RecordNotFound hasn't been defined by the time ExceptionNotifier is loaded. So ActiveRecord::RecordNotFound isn't added to the ignore list.

If I add this to my environment file (like config/environments/development.rb as I'm testing it):

config.middleware.use ExceptionNotifier,
:ignore_exceptions => [ActiveRecord::RecordNotFound]

I get this error:

uninitialized constant ActiveRecord::RecordNotFound (NameError)

So I'd assume that ActiveRecord isn't loaded at this point.

can you provide a failing test reproducing this bug? Thanks!

[jaredhoward]

Not exactly sure what you're asking for. I'll write everything that I'm doing to use ExceptionNotification.

Ruby 1.9.2
Rails 3.0.5
ExceptionNotification gem 2.5.2

Gemfile:

gem 'exception_notification'

config/environments/development.rb:

SHD::Application.config.middleware.use ExceptionNotifier,
  :ignore_exceptions => [ActiveRecord::RecordNotFound]

explicitly call ActiveRecord::RecordNotFound to force it to be loaded.

Now when starting the server, I git this:

Macintosh-4:shd jhoward$ rails server
=> Booting WEBrick
=> Rails 3.0.5 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach

Please let me know if this isn't what you're looking for.

Try placing the SHD::Application.config.middleware.use ExceptionNotifier lines of configuration on the config.ru file, as explained in the README, and let me know if this fixes your issue.

[jaredhoward]

When removing the ExceptionNotifier lines from the environment file and putting them in the config.ru so it now looks like this:

require ::File.expand_path('../config/environment',  __FILE__)
run SHD::Application

SHD::Application.config.middleware.use ExceptionNotifier,
  :ignore_exceptions => [ActiveRecord::RecordNotFound]

The application seems to not even use ExceptionNotification. The server will start up, however, no notifications are made for exceptions. Like if I just create a RuntimeError in a controller by raise "AHHHH". (ExceptionNotification does run for this exception if it's configured in the environment file.)

[jaredhoward]

If I have the ExceptionNotifier lines of code in the application.rb file, it responds the same as if it was in the environment file in that the server boot fails with uninitialized constant error.

[jaredhoward]

Okay, so this is how I was finally able to fix this. I decided to use an initializer to config ExceptionNotifier. So in config/initializers/exception_notification.rb, I have this:

if Rails.env.production?
  require 'active_record/errors'

  SHD::Application.config.middleware.use ExceptionNotifier,
    .........config stuff here
end

You can see that I had to require the active_record/errors file first to insure that ActiveRecord::RecordNotFound was initialized.
