Instance Method Details

#items ⇒ Hash

"items", the option used to configure views of each of a list of cards, is currently the only Hash option (thus this accessor override)

Returns:

  • (Hash)

#normalize_special_options!(opts) ⇒ Object

ACCESSOR_HELPERS methods that follow the normalize_#key pattern are called by accessors (arguably that should be done during normalization!)

def normalize_wrap value
  value = value.split(",").map(&:strip) if value.is_a? String
  Array.wrap(value).compact.flatten
end

#slot_options ⇒ Hash

options to be used in data attributes of card slots (normalized options with standard keys) FIXME: what we really want is options as they were when render was called. normalized is wrong because it can get changed before render. live is wrong because they can get changed after. current solution is a compromise.

Returns:

  • (Hash)
