Here's a good function header given the following:
I wrote the below code

    def decorated(func):
        @wraps(func)
        @writes_models(model)
        def wrapped(data, field):
            if field:
                raise NotImplementedError('Must    use    the    writes_models    decorator    to    update    models')
            return func(data)
    return decorated

What's a good function header?
