升级到Rails 4.1时出现错误 - `method_missing': undefined method `whitelist_attributes=' for ActiveRecord::Base:Class (NoMethodError)

当我从Rails 4.0切换到Rails 4.1时，我遇到了这个错误：

activerecord-4.1.8/lib/active_record/dynamic_matchers.rb:26:in `method_missing': undefined method `whitelist_attributes=' for ActiveRecord::Base:Class (NoMethodError)

我的应用程序中没有使用attr_accessible或attr_protected，所以我想知道为什么出现了问题。

当升级到Rails 4.0时，我已经在我的application.rb文件中添加了以下内容：

config/application.rb:

config.active_record.whitelist_attributes = false

完整的错误日志如下：

我真的很困惑，因为大多数遇到类似问题的人都建议使用gem 'protected_attributes'，但我不想使用它，因为我没有任何attr_accessible或attr_protected。

你有任何想法这个错误是从哪里来的吗？

Rails 4使用strong_params而不是attr_accessible。阅读如何升级的内容：http://edgeguides.rubyonrails.org/upgrading_ruby_on_rails.html - cristian
移除配置设置 whitelist_attributes。 - Nick Veys
我有相同类型的问题，但是错误不同，请你帮忙检查以下链接：http://stackoverflow.com/questions/29227079/issues-with-rails4-and-mongoid-on-production-mode - ratnakar

你可以安全地将config.active_record.whitelist_attributes = false从你的应用程序配置文件中删除。

并且在你的模型类中删除所有white_list_attributes。

祝好！

我们可能需要从development.rb中删除config.active_record.mass_assignment_sanitizer = :strict。 - Sri Murthy Upadhyayula
config.active_record.whitelist_attributes = true也适用吗？因为我得到了相同的错误。 - Fed
