Rails 4 Tip

RAILS_ROOT 被 Rails.root 替换 ActiveRecord 的 White list attributes 被 Strong Parameters Gem 替换 如果使用了 accepts_nested_attributes_for 应当如下使用 ｀Strong Parameters｀ Class User accepts_nested_attributes_for :profile end # strong parameters params.require(:user).permit(:name, profile_attributes: [:xxx, xx])
