Constructor Details

#initialize(options) ⇒ UrlValidator

Public: Creates a new instance, overrides ‘:protocols` if either `:with` or `:in` are defined, to allow for shortcut setters.

Examples:

validates :url, :url => { :protocols => %w{http https ftp} }
# => accepts http, https and ftp URLs

validates :url, :url => 'https'
# => accepts only https URLs (shortcut form of above)

validates :url, :url => true
# => by default allows only http and https

Raises an ArgumentError if the array with the allowed protocols is empty.

Returns a new instance.
