常见的想当然

JSON.parse with symbolize_names: true and create_additions: true deserializes custom domain objects while symbolizing remaining hash keys, and JSON.generate serializes objects that implement as_json.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert JSON.parse raises ArgumentError when :symbolize_names and :create_additions are combined, making addition deserialization mutually exclusive with key symbolization
• assert JSON.generate ignores as_json and serializes arbitrary objects to inspect strings unless to_json is defined, while a to_json returning a Hash raises TypeError
• assert JSON.parse with create_additions: true instantiates registered domain objects via json_create, whereas custom create_id mismatch or missing json_create returns a plain Hash and uninitialized classes raise ArgumentError
• assert JSON.generate stringifies non-string hash keys where nil becomes an empty string, and colliding stringified keys silently overwrite earlier values on parse
• assert core Ruby types like Range and Symbol require json/add extensions to encode json_class structures, which default JSON.parse reads as Hash and create_additions: true restores to exact instances
