Ruby on rails form input error formatting

The default behavior for a regular rails form that has errors is to 1) list the errors in a div, with the text coming from errors_for and 2) to place a div around the offending inputs with a red border. This question is concerning #2.

I'd like to know how rails goes about applying that div with the red border.

I'd like to know because I have some form inputs that aren't generated with f.text_field (for example), but they are attached to a model that can have errors.

I looked around in the source of action_view/helpers/form_tag_helper.rb All I was able to figure out is that form errors aren't applied by form_tag_helper

The red border is added by ActionView::Base.field_error_proc
