当从Rails 4.0切换到Rails 4.1时,我收到这个错误：
activerecord-4.1.8/lib/active_record/dynamic_matchers.rb:26:in `method_missing': undefined method `whitelist_attributes=' for ActiveRecord::Base:Class (NoMethodError)
我没有在我的应用程序的任何地方使用attr_accessible或attr_protected,所以我不知道为什么我有一个问题.
当我移动到Rails 4.0我已经把我的application.rb：
配置/ application.rb中：
config.active_record.whitelist_attributes = false

我真的迷失在这里,因为大多数与bug有关的人与我建议使用gem’protected_attributes但我不想使用它,因为我没有anyattr_accessiblenorattr_protected`.
任何想法,这个bug是从哪里来的？
