#ok?(action) ⇒ Boolean

ok? and ok! are public facing methods to approve one action at a time

fetching: if the optional :trait parameter is supplied, it is passed to fetch and the test is perfomed on the fetched card, therefore:

 trait: :account      would fetch this card plus a tag codenamed :account
 trait: :roles, new: {} would initialize a new card with default ({})

options.

Returns:

  • (Boolean)
