Defined in:

Overview

This check reports views (and partials) that access the params hash. Accessing the params hash directly in views can result in security problems if the value is printed to the HTML output and in general is a bad habit because the controller, which is actually the part of the application that is responsible for dealing with parameters, is circumvented.

Applies to

  • partials and regular views
