If allow_nan is false, then it will be a ValueError to serialize out of range float values (nan, inf, -inf) in strict compliance of the JSON specification, instead of using the JavaScript equivalents (NaN, Infinity, -Infinity). indent:应该是一个非负的整型,如果是0就是顶格分行显示,如果为...

This code runs in a production api layer, and is exersized such that we can't use the one-line workaround suggested (just doing a full serialize (.json()) + full deserialize). We implemented a custom function to do this, descending the result of .dict() and converting types to json...
Update: Python now has its own json handler, simply use import json instead of using simplejson. The Django serializers module is designed to serialize Django ORM objects. If you want to encode a regular Python dictionary you should use simplejson, which ships with Django in case you don't...
定义一个自定义的JSON编码器,以便将自定义类型转换为字典。 使用json.dump()函数将数据序列化为JSON字符串,并指定自定义编码器。 定义一个自定义的JSON解码器,以便将字典转换为自定义类型。 使用json.load()函数将JSON字符串反序列化为数据结构,并指定自定义解码器。
