В развернутом приложении Rails 2.3.5 я получаю следующую ошибку:
NoMethodError (неопределенный метод `to_sym 'для nil: NilClass):
Моя локальная тестовая установка приложения, использующего Sqlite, не выдает ошибку, но мое развернутое приложение под управлением Mysql делает это. Единственное другое различие между ними заключается в том, что я использую Ruby 1.8.7 на моей локальной машине и 1.8.6 на моем сервере развертывания.
Я включил код из User.rb и журнал ошибок ниже. Я настроил это после декларативной авторизации и встроенной авторизации Railscasts.
Любая помощь будет принята с благодарностью!
РЕДАКТИРОВАТЬ: Вот код для application_controller, где я устанавливаю current_user с использованием before_filter:
class ApplicationController < ActionController::Base
helper :all
helper_method :current_user_session, :current_user
before_filter :set_current_user
protected
def set_current_user
Authorization.current_user = current_user
end
def current_user_session
return @current_user_session if defined?(@current_user_session)
@current_user_session = UserSession.find
end
def current_user
@current_user = current_user_session && current_user_session.record
end
end
-
User.rb:
class User < ActiveRecord::Base
acts_as_authentic
has_many :products
has_many :transactions
ROLES = %w[admin dmstaff staff faculty]
def role_symbols
[role.to_sym]
end
end
