錯誤切換到Rails 4.1時 - `的method_missing '：未定義的方法`whitelist_attributes =' ActiveRecord的::基地：類（NoMethodError）

當從滑軌4.0切換到4.1的Rails我正在此錯誤：錯誤切換到Rails 4.1時 - `的method_missing '：未定義的方法`whitelist_attributes =' ActiveRecord的::基地：類（NoMethodError）

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

我沒有在我的應用程序的任何地方使用attr_accessible或attr_protected，所以我不知道爲什麼我有問題。

當移動到Rails 4.0，我已經把我的application.rb中：

的config/application.rb中：

config.active_record.whitelist_attributes = false

我我真的失去了這裏，因爲大多數有漏洞的人都建議使用gem'protected_attributes but I don't want to use it as I don't have any attr_accessible nor attr_protected`。

任何想法，這個錯誤來自哪裏？

Rails 4使用strong_params而不是attr_accessible。閱讀如何升級http://edgeguides.rubyonrails.org/upgrading_ruby_on_rails.html – cristian 2014-12-18 22:59:10

刪除配置設置「whitelist_attributes」。 – 2014-12-18 23:28:37

我有同樣類型的問題，但不同的錯誤，請你檢查以下鏈接 http://stackoverflow.com/questions/29227079/issues-with-rails4-and-mongoid-on-production-mode – ratnakar 2015-03-26 09:33:25

您可以安全地刪除 config.active_record.whitelist_attributes =假

從您的應用程序配置文件。

並刪除模型類中的所有white_list_attributes。

乾杯，

也，我們可能必須從development.rb刪除config.active_record.mass_assignment_sanitizer =：strict – 2015-06-13 08:20:49

也適用於'config.active_record.whitelist_attributes = true'嗎？因爲我得到同樣的錯誤。 – FedericoCapaldo 2017-03-12 05:45:09

錯誤切換到Rails 4.1時 - `的method_missing '：未定義的方法`whitelist_attributes =' ActiveRecord的::基地：類（NoMethodError）
