mongoengine-忽略多余的字段以进行模式验证 [英] mongoengine - Ignore extra fields for schema validation

问题描述

我正在尝试查询我的数据库.有些记录当前具有我的模型架构中未包括的额外字段(由于错误，但是我想处理这些情况).当我尝试查询数据库并将记录转换为架构时，出现以下错误:

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'

由于数据库中与架构不同的额外字段.

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

是否有一种方法可以忽略对mongoengine中的其他字段进行此模式验证?

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

推荐答案

要在加载数据时有多余字段时忽略此错误，请在元字典中将strict设置为False.

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}
