Namespaced resources fail in production when controllers are not namespaced

#1458

If you have this route definition:


map.namespace :time do |time|
    time.resources :tags, :controller => 'tags'
end

and the controller is defined as


class TagsController < ApplicationController

in app/controllers/tag_controller.rb, Rails 2.2 fails in production mode (NOT in development mode), with the following exception:


(ArgumentError) "Object is not missing constant TagsController!"

Here's the backtrace:


APP_ROOT/vendor/rails/activesupport/lib/active_support/dependencies.rb:419:in `load_missing_constant'
APP_ROOT/vendor/rails/activesupport/lib/active_support/dependencies.rb:77:in `const_missing'

I've no idea if this is supposed to work in the first place, but in development mode everything works just fine and is peachy.

I'm getting the same problem. In slightly different context, not related to routing.

I've got my model


class Persona < ActiveRecord::Base
 ...
end

And I've got in another model the following:


class Coeficiente < ActiveRecord::Base
 ...
 def private.db_field(class_name)
  table = eval "#{class_name}.table_name"
 end
 ...
  db_field(Persona)
 ...
end

here's my backtrace

Pratik
Is this still an issue ? Could you please submit a failing test case ? http://guides.rails.info/contrib... should be helpful.

Thanks

Still getting this problem...

routes.rb

map.namespace :account do |account|
```
account.resources :sponsorships
account.resource :profile, :controller => "users"
```
end

A login form with :url => account_profile_path generates this error:
@@@Processing ApplicationController#create (for ... at 2009-05-19 10:57:44) [POST] Parameters: {"user"=>{"password_confirmation"=>"[FILTERED]", "password"=>"[FILTERED]", "email"=>"*****@gmail.com"}, "commit"=>"Register", "action"=>"create", "controller"=>"account/users"}

NameError (uninitialized constant Account::UsersController):@@@

No idea why it's even processing ApplicationController... :S

Again, works fine in development, breaks in production... :(

@Thomas, you need to reset the namespace not the controller in your nested resource so it should look like this otherwise it will assume you have a Time::TagsController:

{{{ map.namespace(:time) do |time|
```
time.resources :tags, :namespace => ''
```
end }}}

Ah sorry wrong markup:

  map.namespace(:time) do |time|
    time.resources :tags, :namespace => ''
  end
