Puma 发现了这个错误：无效的选项键：raise_on_unfiltered_pa​​rameters

Question

I am learning Ruby on Rails with Michael Hartl's book Ruby on Rails™ Tutorial: Learn Web Development with Rails, Fourth Edition . I got the error message when trying the toy_app . Does anyone know what's wrong?

Puma caught this error: Invalid option key: raise_on_unfiltered_parameters= (RuntimeError)

Update: commenting out raise_on_unfiltered_parameters resolves the issue.

Answer 1

I was having this same issue and thi was how i solved it: go to the

config/initializers/new_framework_defaults.rb

and comment or delete this line of code:

 Rails.application.config.action_controller.raise_on_unfiltered_parameters = true

i hope this helps
