#urlize(options = {}) ⇒ Object

Convert a string to a format suitable for a URL without ever using escaped characters. It calls strip, removeaccents, downcase (optional) then removes the spaces (optional) and finally removes any characters matching the default regexp (/[^-_A-Za-z0-9]/).

Options

  • :downcase => call downcase on the string (defaults to true)

  • :convert_spaces => Convert space to underscore (defaults to false)

  • :regexp => The regexp matching characters that will be converting to an empty string (defaults to /[^-_A-Za-z0-9]/)
