Я абсолютно новичок в Ruby и Rails и получаю сообщение об ошибке при выполнении этой команды:
rails generate scaffold User name:string email:string
Вот полная ошибка, которую я получаю:
/Users/ad7863/rails_project/demo_app/config/application.rb:7: undefined method `groups' for Rails:Module (NoMethodError)
from /Library/Ruby/Gems/1.8/gems/railties-3.0.11/lib/rails/commands.rb:15:in `require'
from /Library/Ruby/Gems/1.8/gems/railties-3.0.11/lib/rails/commands.rb:15
from script/rails:6:in `require'
from script/rails:6
Iя следую учебному пособию по Ruby on Rails, которое можно найти здесь .
Я использую Rails версии 3.0.11.
Кто-нибудь знает, что я делаю неправильно?
Спасибо.
Редактировать: содержимое моего файла application.rb:
require File.expand_path('../boot', __FILE__)
require 'rails/all'
if defined?(Bundler)
# If you precompile assets before deploying to production, use this line
Bundler.require(*Rails.groups(:assets => %w(development test)))
# If you want your assets lazily compiled in production, use this line
# Bundler.require(:default, :assets, Rails.env)
end
