Instance Method Details

#initialize(_name, options = EMPTY_HASH) ⇒ undefined

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Initialize a length comparable attribute

Parameters:

  • _name (#to_sym) —

    the attribute name

  • options (#to_hash) (defaults to: EMPTY_HASH) —

    the options for the attribute

Options Hash (options):

  • :required (Boolean) — default: true —

    if true, then the value cannot be nil

  • :minimum_length (::Integer) —

    The minimum string length for a valid value

  • :maximum_length (::Integer) —

    The maximum string length for a valid value

Returns:

  • (undefined)
