Acronym won't pluralize correctly causing circular dependencies

Question

I would like to name my controller ESCsController, ESC being the acronym in question. I found the rails inflection docs which describe a way in which to accomplish this.

http://api.rubyonrails.org/classes/ActiveSupport/Inflector/Inflections.html

Note: Acronyms that are passed to pluralize will no longer be recognized, since the acronym will not occur as a delimited unit in the pluralized result. To work around this, you must specify the pluralized form as an acronym as well:

acronym 'API'
camelize(pluralize('api')) #=> 'Apis'

acronym 'APIs'
camelize(pluralize('api')) #=> 'APIs'

I created my controller and models after adding this to environment.rb

ActiveSupport::Inflector.inflections { |i| 
   i.acronym 'ESC'
   i.acronym 'ESCs'
}

Tested in the console these work perfectly. 'ESC'.pluralize() returns ESCs and 'ESCs'.singularize() returns ESC as expected

Controllers and models were generated through rails generate model ESC and rails generate controller ESCs respectively. This created escs_controller.rb and the model esc.rb as expected.

In my routes.rb I used to have

resources :ESCs, path: '/parts/escs'

which returned this error: 'ESCs' is not a supported controller name. This can lead to potential routing problems. See http://guides.rubyonrails.org/routing.html#specifying-a-controller-to-use

I ended up changing it to:

resources :ESCs, controller: 'escs', path: '/parts/escs'

However, now whenever I try and visit a page I get a circular dependency error:

Circular dependency detected while autoloading constant EscsController

Anyone know what's going on? It looks like whatever is trying to load the controller isn't seeing that it should be ESCsController and not EscsController. I'm new to rails so this could be a simple problem...

I'm using Rails 4.0.2

Here's the relevant part of the full stack trace.

Try moving code that adds the new inflections from environment.rb to config/initializers/inflections.rb then reload the server. Also, you don't need to specify a controller option for your route, just make it resources :escs, path: '/parts/escs' and it shall work fine.
