带有firebase-admin python sdk的Firebase Firestore Server时间戳 [英] Firebase Firestore Server Timestamp with firebase-admin python sdk

问题描述

有一种方法可以在 firebase-admin python sdk 中添加服务器时间戳? 我尝试:

There is a way to add server timestamps in firebase-admin python sdk? I try:

firestore.SERVER_TIMESTAMP
firestore.constants.SERVER_TIMESTAMP

但是，我得到了这个例外:

but, i get this exception:

TypeError: ('Cannot convert to a Firestore Value', <object object at 0x10380fc20>, 'Invalid type', <class 'object'>)

推荐答案

firestore.SERVER_TIMESTAMP为我工作.这是完整的示例:

firestore.SERVER_TIMESTAMP worked for me. Here's the full example:

import firebase_admin
from firebase_admin import firestore

# I have GOOGLE_APPLICATION_CREDENTIALS configured.
firebase_admin.initialize_app()
client = firestore.client()
result = client.collection('test').document('foo').set({
    'mytime':firestore.SERVER_TIMESTAMP
})
print(result)

此打印输出:

update_time {
  seconds: 1523491166
  nanos: 932097000
}

该值已按预期存储在数据库中.

And the value was stored in database as expected.
