Does voluptuous support multiple field validations

[jeff1evesque]

Can, I validated 2+ fields at the same time, and receive feedback, on 2+ errors at a given validation instance? The way I've implemented, it seems to catch only the first error. When I fix the first error, then run the voluptuous validation again, the next error is raised, and so forth. Is this generally how validation is implemented either internally with voluptuous, or how the error is caught?

I have the following schema:

            schema = Schema({
                Required('collection'): All(unicode, Length(min=1)),
                Required('model_type'): In(model_type),
                Required('session_type'): 'model_generate',
                Optional('stream'): Any('True', 'False'),
                Required('sv_kernel_type'): In(sv_kernel_type),
                Optional('gamma'): Any(int, float),
                Optional('penalty'): Any(int, float),
            })

If I were to validate my schema:

premodel_settings: {'sv_kernel_type': u'linear', 'stream': 'False', 'session_type': u'model_generate', 'collection': u'collection-1', 'penalty': u'161528', 'model_type': u'svm', 'gamma': u'164'}

As follows:

        try:
            schema(premodel_settings)

        except Exception, error:
            self.list_error.append(error)
            return error

It seems I'm only capturing one error twice:

"expected int for dictionary value @ data['penalty']"

I've commented my exact use case, on an issue, I've just recently quasi finished.

Also, thank you for developing and maintaining this project. I was previously using jsonschema, and this seems a little more robust so far.

Ah, ok found MultipleInvalid, which will allow multiple keys to be validated.
