Attach a rails web console to any page by adding ?web_console=
# config/initializers/web_console.rb
WebConsoleBeforeAction = ->(controller) do
controller.console if controller.params[:web_console]
end
ApplicationController.before_action(WebConsoleBeforeAction) if defined?(WebConsole) && Rails.env.development?
# NOTE:
# For security reasons only do this in development.
