有没有办法让设计与 Rails 4.0rc1 一起工作?尝试启动 rails 服务器甚至生成设计视图时出现以下错误:
/Users/scott/.rvm/gems/ruby-2.0.0-p195@rails/gems/activemodel-4.0.0.rc1/lib/active_model/deprecated_mass_assignment_security.rb:14:in `attr_accessible':
`attr_accessible` is extracted out of Rails into a gem. Please use new recommended protection model for params(strong_parameters) or add `protected_attributes` to your Gemfile to use old one. (RuntimeError)
