We can do so by adding an array value to the param:

params.permit(:email, :name, sites: [])

We can even use nested arrays:

We can match against URI::MailTo::EMAIL_REGEXP.

  def valid_email?(email)
    email && email.match?(URI::MailTo::EMAIL_REGEXP)
  end

We can match against %r{^(http|https)://[a-z0-9]+([\-.]{1}[a-z0-9]+)*\.[a-z]{2,6}(:[0-9]{1,5})?(/.*)?$}ix.

Non Rails version:

  VALID_URL_REGEXP = %r{^(http|https)://[a-z0-9]+([\-.]{1}[a-z0-9]+)*\.[a-z]{2,6}(:[0-9]{1,5})?(/.*)?$}ix.freeze

 def valid_url?(url)

Get on all fours and slowly move back and forth from a downward spinal curve with the head looking up like a cat and then move into a rounded spine while the head looks down like a camel. Each cycle should take about three to four seconds. 7-8 cycles are all that is needed.

Gist: Only do 7-8 cycles. More than that could be bad.
