Rails Validations Do Not Work with 'rails-bootstrap-forms/bootstrap_form_for'

Question

I am using this gem: https://github.com/bootstrap-ruby/rails-bootstrap-forms. The gem is supposed to highlight the input box in red if a validation is not met. I have a couple issues. First, the inline validation errors are not working. Secondly, and more importantly, my model validation errors are not working at all.

How do I change the validations to make sure they work? Is there something special I need to do to make the gem work on the front end? Or would it be best to use another method for front end validation errors?

Thank you so much!
