Hi there

I’m trying to install this rack application:  
[http://fuelyourcoding.com/set-rails-logging-on-fire/](http://fuelyourcoding.com/set-rails-logging-on-fire/)

However, my rails3 setup is not picking up my lib file:

app/lib/rack/firebug\_logger.rb

which contains:

module Rack  
class FirebugLogger  
…  
end  
end

And in my config/environments/development.rb :

App::Application.configure do  
…  
config.middleware.use Rack::FirebugLogger  
end

But rails3 is not finding my lib file ☹

uninitialized constant Rack::FirebugLogger (NameError)

Any clues?

thanks!

Is “app/lib/rack/firebug\_logger.rb” simply the wrong direcotry?

Or is there something I need to do to make it work?

If I put…

module Rack  
class FirebugLogger  
…  
end  
end

… inside my application controller it all works fine –  
Rack::FirebugLogger is accessible and works.

thanks for any advice

Does anyone have any clues of suggestions?

I’m not even sure how to manually load Rack::Firebugger in “app/lib/  
rack/firebug\_logger.rb”

But would rather it just automatically loaded

There is a typo on the blog post you referred to. It should go in lib/  
not app/lib.

Also from the same post:  
“Rails autoloads (and namespaces) any code placed in the lib directory,  
so that is where we’ll place our FirebugLogger code.”
