For anyone coming across this that does not know how to override the devise error messages with bootstrap.

1. Create file named:

/app/helpers/devise_helper.rb

1. Add the following code:

module DeviseHelper
 def devise_error_messages!
  return '' if resource.errors.empty?

   messages = resource.errors.full_messages.map { |msg| content_tag(:li, msg) }.join
   sentence = I18n.t('errors.messages.not_saved',
   count: resource.errors.count,
   resource: resource.class.model_name.human.downcase)

   html = <<-HTML
   
 x
    
#{sentence}
    #{messages}
   
   HTML

   html.html_safe
 end
end
