        # 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.
