end

#save(options = {}) ⇒ Boolean

Persist the record to the database. If this is a new record, it will be saved using an INSERT statement. If it is an existing record, it will be persisted using a series of ‘UPDATE` and `DELETE` statements which will persist all changes to the database, including atomic collection modifications.

Parameters:

  • options (Options) (defaults to: {}) —

    options for save

Options Hash (options):

  • :validate (Boolean) — default: true —

    whether to run validations before saving

  • :consistency (Symbol) —

    what consistency with which to persist the changes

  • :ttl (Integer) —

    time-to-live of the updated rows in seconds

  • :timestamp (Time) —

    the writetime to use for the column updates

Returns:

  • (Boolean) —

    true if record saved successfully, false if invalid
