Rails form errors - validation

Question

I'd like to be able to highlight fields that don't pass validation. I'm using simple_form, and the error messages it displays just don't look good to me. I'm listing the errors above the form & I'd like to highlight (change the color of) the fields that contain invalid values. Is there an easy way of doing this?

yes it's very easy, you will likely find that the field with errors will have a class of ".field_with_errors" or something similar applied to it

just style all inputs that fall within that class to have 2px solid red border

i.e.

// style.sass
.field_with_errors
  input
    border: 2px solid red

This set me on the right track -- ultimately, I also had to add field_with_error_fix.rb to config/initializers. The file contains the following code: ActionView::Base.field_error_proc = Proc.new { |html_tag, instance| "<span class=\"fieldWithErrors\">#{html_tag}</span>" }

You could also take a look at client-side-validations. You can style and display errors inline, and it supports simple_form.
