Domain validator #94

Open skalee opened 6 years ago

skalee commented 6 years ago

A separate validator for fields storing domains may be useful. Consider following example:

class Site
  include ActiveModel::Validations

  attr_accessor :registered_domain
  validates :registered_domain, domain: { resolvable: true }
end

object = Site.new

object.registered_domain = "google.com"
object.valid? # => true

object.registered_domain = "asdfasdfasd.asdfasdfasdf.com"
object.valid? # => false

This is just an early concept. I'm not yet sure what validation options will be useful. I guess checking that domain is resolvable, and that host is reachable. Also some checks like if it fits given regexp, or is subdomain of given domain, things like that..
