Instance Method Details

#blank? ⇒ Boolean

Catch whitespace-only strings, overriding the inherited Object#blank?. Guarded on String’s OWN methods — not method_defined?, which would see the inherited Object#blank? and skip, leaving the whitespace-blind version. This still defines our version normally, but yields to any external String#blank? (e.g. ActiveSupport) rather than clobbering it.

Returns:

  • (Boolean)
