将 JSON 模式转换为 python 类

到目前为止，我所能找到的最接近的是warlock，它宣传这个工作流:

Build your schema

>>> schema = {
    'name': 'Country',
    'properties': {
        'name': {'type': 'string'},
        'abbreviation': {'type': 'string'},
    },
    'additionalProperties': False,
}

Create a model

>>> import warlock
>>> Country = warlock.model_factory(schema)

Create an object using your model

>>> sweden = Country(name='Sweden', abbreviation='SE')

However, it's not quite that easy. The objects that Warlock produces lack much in the way of introspectible goodies. And if it supports nested dicts at initialization, I was unable to figure out how to make them work.

To give a little background, the problem that I was working on was how to take Chrome's JSONSchema API and produce a tree of request generators and response handlers. Warlock doesn't seem too far off the mark, the only downside is that meta-classes in Python can't really be turned into 'code'.

Other useful modules to look for:

• jsonschema - (which Warlock is built on top of)
• valideer - similar to jsonschema but with a worse name.
• bunch - An interesting structure builder thats half-way between a dotdict and construct

If you end up finding a good one-stop solution for this please follow up your question - I'd love to find one. I poured through github, pypi, googlecode, sourceforge, etc.. And just couldn't find anything really sexy.

For lack of any pre-made solutions, I'll probably cobble together something with Warlock myself. So if I beat you to it, I'll update my answer. :p
