Rails: Action error in production but not in development - ruby-on-rails

Question

Can anyone explain why I keep getting an error in production but not in development? Relevant parts:
get: /user/logout
ActionController::RoutingError (uninitialized constant User::SessionController):
activesupport/lib/active_support/inflector/methods.rb:229:in `block in constantize'

Routes:
Application1::Application.routes.draw do
match('/auth/:provider/callback' => 'session#create', :format => false)
root(:to => 'blog/archives#index', :format => false)
namespace(:user) do
match('/logout' => 'session#destroy', :format => false)
end
namespace(:blog) do
match('/archive/:slug' => 'archive#show', :format => false)
constraints(:page => /page\d+/) do
match('/archives/:page' => 'archives#index', :format => false)
end
end
end
I am using Rails 3.2.3 with the latest Omniauth.

You have created a namespace user and therefore you should place the session controller that defines the destroy action in this path:
/app/controllers/user/session_controller.rb
Then you can do stuff like:
Create a file in /app/controller/user/base_controller.rb that defines this:
class User::BaseController < ApplicationController
# Whatever you want here
end
And define the sessions controller located in /app/controllers/user/session_controller.rb as:
class Users::SessionsController < User::BaseController
def destroy
# whatever you want destroy to do..
end
end
Read this for more documentation about namespaces and routing.
