How to raise an exception when unpermitted parameters are submitted?

Question

I found this bit of code here:

ActionController::Parameters.action_on_unpermitted_parameters = :raise

I tried putting this in config/environments/development.rb, but it didn't seem to work. Where should I put it? (I only want this for development env.)

Answer 1

Put this into config/environments/development.rb

config.action_controller.action_on_unpermitted_parameters = :raise

this will raise ActionController::UnpermittedParameters
