How to customize rails form errors?

Question

Ruby on Rails

Friends, faced with a trivial but unpleasant problem. When validating a form, the framework automatically wraps the label and input in div.field_with_errors. I need to change this behavior, override the error template for fields and labels throughout the application. Who faced - tell me how you solved this problem.
PS Under Rails 4

maybe it's easier to add a css class?
