Rails Rails 配置的问题，请指教
Rails.application.config.action_controller.raise_on_unfiltered_parameters = true
这个配置位于 config/initializers/new_framework_defaults.rb 文件，默认值是 true，但启动服务后访问应用报错（如下），改为 false 才正常，这个配置具体作用是干什么的？有没有文档提供一下？为什么会出现这种错误？我使用的 Rails 版本是 5.0.0.1，Ruby 版本是 2.3.7。

谢谢，看了文档后，我调试了一下，还是不怎么理解
文档说明
# make hash conversion of the parameters raise an error if they are not permitted.
config.action_controller.raise_on_unfiltered_parameters
