-
.narrow(attributes, options = {}) ⇒ Object
Necessary because Rails has removed the narrowing of attributes using :only and :except on Base#attributes.
- .strip(record_or_string, options = {}) ⇒ Object
- .strip_record(record, options = {}) ⇒ Object
- .strip_string(value, options = {}) ⇒ Object
- .validate_options(options) ⇒ Object
