mongoengine的save方法已弃用? [英] mongoengine save method is deprecated?

问题描述

我想知道为什么我的python为什么不推荐使用mongoengine save()方法吗?我没有在官方文档 https://mongoengine中看到有关此信息的任何信息.阅读thedocs.io/en/v0.9.0/apireference.html

I wonder why my python says that mongoengine save() method is deprecated? I don't see any info about this into official documentation https://mongoengine.readthedocs.io/en/v0.9.0/apireference.html

class MyModel(Document):
    user_id = StringField(required=True)
    date = DateTimeField(required=True, default=datetime.datetime.now)

my = MyModel()
my.user_id = 'user'
my.save()

现在我看到:

/Library/Python/2.7/site-packages/mongoengine/document.py:340: 弃用警告:不建议使用保存.使用insert_one或replace_one 代替

/Library/Python/2.7/site-packages/mongoengine/document.py:340: DeprecationWarning: save is deprecated. Use insert_one or replace_one instead

我已经安装了python 2.7，还安装了pymongo，mongoengine和bottle-mongo(也许有一些问题吗?)

I've python 2.7 and also installed pymongo, mongoengine and bottle-mongo (maybe some issues with that?)

推荐答案

MongoEngine包装了PyMongo，它在PyMongo 3.0中已弃用保存":

MongoEngine wraps PyMongo, which deprecated "save" in PyMongo 3.0:

MongoEngine可能需要弃用其save方法，或取消弃用警告，或者可能需要其他一些修复程序来处理此PyMongo更改.我建议您搜索MongoEngine的错误跟踪器，如果尚未发现该问题，请报告该问题.

MongoEngine might need to deprecate its save method, or suppress the deprecation warning, or perhaps some other fix to handle this PyMongo change. I recommend you search MongoEngine's bug tracker and report this issue if it has not been already.
