Rails form errors - validation

I'd like to be able to highlight fields that don't pass validation. 开发者_高级运维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

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