Ruby on rails：rake 不工作

Question

当我尝试在我的 Rails 中运行任何 rake 测试时，它会给我错误消息“未定义的方法 `whitelist_attributes”。我不知道它为什么会来。

我得到的错误是：

---

    NoMethodError: undefined method `whitelist_attributes=' for #  <Class:0x50de7d8>
  C:/Users/Arvind/project/book/config/initializers/devise.rb:21:in `block in <top (required)>'
 C:/Users/Arvind/project/book/config/initializers/devise.rb:4:in `<top (required)>'
 C:/Users/Arvind/project/book/config/environment.rb:8:in `<top (required)>'
     Tasks: TOP => environment
    (See full trace by running task with --trace)`enter code here`

我的 gem 文件如下所示：

您的config/application.rb 文件中是否定义了config.active_record.whitelist_attributes？如果是这样，请删除该行或将其设置为 false：config.active_record.whitelist_attributes = false

您的模型类中是否定义了white_list_attributes？如果是这样，请删除这些。您应该在 4.2.1 中使用 strong_parameters。 https://github.com/rails/strong_parameters
