This will add <%= debug(params) if Rails.env == 'development' %> to the bottom of app/views/layouts/application.html.erb, before the closing </body> tag.

This will then render the debugged output of the params hash on every page in development.

Run this command in your Rails app directory in the terminal:

rails app:template LOCATION=""
