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

This is my URL validator, using Ruby's built-in parser

class UrlValidator < ActiveModel::EachValidator
  def validate_each(record, attribute, value)
    p = URI::Parser.new

    valid = begin
      p.parse(value)
      true
    rescue
      false
    end

    unless valid
      record.errors[attribute] << (options[:message] || "is an invalid URL")
    end
  end

end
