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'
  activesupport/lib/active_support/inflector/methods.rb:228:in `each'

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.
