Nodes::Controller

This method will be invoked before the action, you can override it to run any arbitrary things before the action. Overrides should call super to make sure that the ancestor's #before_action method is invoked, unless it's a deliberate choice to not call it.

If the method rendered anything, redirected or called #head then the request will stop being processed. None of #around_action, the actual action or #after_action will be called.
