Validation for URL/Domain using Regex? (Rails)

Question

I am trying to create a validation that checks to make sure a domain/url is valid for example \"test.com\"

def valid_domain_name?
  domain_name = domain.spli         


        

Answer 1

What works for me is

def validate_url(text)
  uri = URI.parse(text)
  raise URI::InvalidURIError unless uri.kind_of?(URI::HTTP) || uri.kind_of?(URI::HTTPS)
  rescue URI::InvalidURIError
    errors.add(:url, 'is invalid')
  end
end
