mongoengine - Ignore extra fields for schema validation

Question

I am trying to query my database. 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' 

Because of the extra fields in the database that differ from the schema.

Is there a way to ignore this schema validation for extra fields in mongoengine?

Answer 1

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}
