흔히 이렇게 알고 있다

Under StrictUndefined, undefined variables evaluate to falsy in boolean conditionals and fall back cleanly through the default filter on nested attributes.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• Boolean evaluation of an undefined variable in an if condition raises UndefinedError under StrictUndefined instead of evaluating as falsy
• Accessing a nested attribute on an undefined parent raises UndefinedError even when piped to the default filter under StrictUndefined
• Piping a top-level undefined variable directly to the default filter returns the fallback value without raising UndefinedError under StrictUndefined
• Accessing a missing attribute on a defined dictionary returns the fallback value when piped to the default filter under StrictUndefined
• Testing an undefined variable with the is defined test returns False without raising UndefinedError under StrictUndefined
• ChainableUndefined permits chained attribute lookups on undefined parents to resolve through the default filter
