MongoDB Node check if objectid is valid

Question

How can I check whether an ObjectID is valid using Node\'s driver

I tried :

var BSON = mongo.BSONPure;
console.log(\"Validity: \"  + BSON.ObjectID.is

You can use Cerberus and create a custom function to validate and ObjectId

from cerberus import Validator
import re

class CustomValidator(Validator): 
    def _validate_type_objectid(self, field, value):
        """ 
        Validation for `objectid` schema attribute.

        :param field: field name.
        :param value: field value.
        """
        if not re.match('[a-f0-9]{24}', str(value)):
            self._error(field, ERROR_BAD_TYPE % 'ObjectId')

## Initiate the class and validate the information
v = CustomValidator()

schema = {
    'value': {'type': 'objectid'}
}
document = {
    'value': ObjectId('5565d8adba02d54a4a78be95')
}

if not v(document, schema):
    print 'Error'
