how can I set the parameter allow_unknown to support unknown parameters

Hello, how can I set the parameter allow_unknown to support unknown parameters

Facing the same problem. by looking at the code it seems impossible to put it at the top level. Because the decorator just uses validator = Validator(schema) there is no way to add it to the top. For internal dictionaries you can just use :

{
   'a_text': {'type': 'string', 'required': True},
   'a_dict': {
                'type': 'dict',
                'required': True,
                'schema': { .... } ,
                'allow_unknown': True
        }
}

Maybe there is another way to do it but can't find anything on Cerberus documentation. I will try to make a PR when I have time. For now I recommend creating a fork and doing it yourself, something like:

def validate_json(schema, clean=False, status_code=400, allow_unknown=False):
    '''Decorator. Validates request body json.

    When *clean* is true, normalized data is passed to the decorated method
    as *valid_json*.

    Args:
        schema (dict): Cerberus-compatible schema description
        clean (bool): should cleaned json be passed to the decorated method
        status_code (number): status code to return when data is incorrect
    '''
    validator = Validator(schema, allow_unknown)

    def vd(f):
            ...... # the rest of the function, nothing needs to be changed

or maybe:

def validate_json(schema, clean=False, status_code=400, **kwargs):
    '''Decorator. Validates request body json.

    When *clean* is true, normalized data is passed to the decorated method
    as *valid_json*.

    Args:
        schema (dict): Cerberus-compatible schema description
        clean (bool): should cleaned json be passed to the decorated method
        status_code (number): status code to return when data is incorrect
    '''
    validator = Validator(schema, **kwargs)

    def vd(f):
            ...... # the rest of the function, nothing needs to be changed

for a more generic solution.

Obs: I haven't tested any of this code yet.
