If you are working with #Cement, #Flask or other python frameworks that do not give ODM (Object Document Mapper) out of the box, you can use MongoEngine for MongoDB.
It has all the capabilities that you can almost imagine for an ODM to define schema and apply restrictions to it. You'll hear more about it later.

How to ignore extra fields for schema validation in Mongoengine?

Some records currently have extra fields that are not included in my model schema (by error, but I want to handle these cases). When I try to query the DB and transform the records into the schema, I get the following error:

FieldDoesNotExist
The field 'X' does not exist on the document 'Y'

For ignoring this error when having extra fields while getting data, set strict to False in your meta dictionary.

class User(Document):
    email = StringField(required=True, unique=True)
    password = StringField()
    meta = {'strict': False}
