Devise - NoMethodError in Registrations#new controller

Every开发者_Python百科thing worked fine on my development machine (windows xp, ROR 3.0.3, SQLite3).

When I moved the application to the production server (FreeBSD 8.2-RELEASE, Apache 2.2, ROR 3.0.4, MySQL), this error appeared, but only on new registration page.

When I try to login (there are no users in the database), password check seems to work (it says that password incorrect, which is fine).

The problem occurs only on the production server, no problem on the developement server. What could it be?

Thanks!

routes.rb:

  #USERS
  get "/user/stat"
  devise_for :users do
    get "/login" => "devise/sessions#new"
    get "/logout" => "devise/sessions#destroy"
  end
  get "/users" => "user#index"
  resources :user

registations_controller.rb:

  # GET /resource/sign_up
  def new
    build_resource({})
    render_with_scope :new
  end

  protected

    # Build a devise resource passing in the session. Useful to move
    # temporary session data to the newly created user.
    def build_resource(hash=nil)
      hash ||= params[resource_name] || {}
      self.resource = resource_class.new_with_session(hash, session)
    end

log/production.log:

Change the owner of the app directory to the same user as HTTPD process owner:

$ chown -R <username> <your_app_dir>

e.g.

$ chown -R www /usr/local/www/apache22/data

and update Devise:

$ bundle update

Gemfile specifies the latest Devise version:

gem 'devise'

That worked for me.
