You can extend from mon.DynamicDocument.

class AF(mon.DynamicDocument):
  meta = {
    'collection': 'af'
  }

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

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

Answer 3

I think you want skip schema validation, so when you save your document

document_name.save(validate=False)

Answer 4

I believe you want to use a DynamicDocument instead of a Document when defining your model and that will allow extra fields in the db schema to be ignored.
