TypeError：＆＃x27;收集＆＃x27;对象不可呼应（delete_one错误）
这段代码运行得很好。它访问 Mongo 数据库的集合，提取数据并删除最旧的数据。然而，从一周前开始，虽然我可以访问数据，过滤和显示它们，但我无法删除它们，因为它告诉我 delete_one 不是“Collection”的方法数据库处于活动状态（它使用 docker-compose），正如我所说，您可以访问数据，并且每分钟都会添加新数据（在本例中为文档）。
with MongoClient(MONGODB_URI) as client: # MongoDB
db = client['twitter_raw']
tweets_collection = db['tweets_venezuela']
# number of documents in the collection
mydoc = tweets_collection.find().count()
print("The number of documents in collection : ", mydoc)
print(tweets_collection)
#tweets_collection.delete_one({'created_at':"2022-02-16 04:12:22"})
# print(tweets_collection.find_one())
for row in tweets_collection.find({}):
fecha = row["created_at"]
if(str(fecha) < "2022-02-17 04:12:22"):
tweets_collection.delete_one({'created_at':fecha})
else:
print(fecha)
有谁知道会发生什么？这是非常罕见的，我在互联网上找不到任何东西。 提前致谢。
This code was working perfectly. It accesses a collection of the Mongo database, extracts the data and deletes the oldest data. However, since a week ago, although I can access the data, filter and display them, I can not delete them because it tells me that delete_one is not a method of "Collection" The database is active (It uses a docker-compose) and, as I said, is that you can access the data and every minute that passes new data (Documents in this case) are added.
with MongoClient(MONGODB_URI) as client: # MongoDB
db = client['twitter_raw']
tweets_collection = db['tweets_venezuela']
# number of documents in the collection
mydoc = tweets_collection.find().count()
print("The number of documents in collection : ", mydoc)
print(tweets_collection)
#tweets_collection.delete_one({'created_at':"2022-02-16 04:12:22"})
# print(tweets_collection.find_one())
for row in tweets_collection.find({}):
fecha = row["created_at"]
if(str(fecha) < "2022-02-17 04:12:22"):
tweets_collection.delete_one({'created_at':fecha})
else:
print(fecha)
Does anyone know what could be going on? It's quite rare and I can't find anything on the internet.
Thanks in advance.

而是使用它“ tweets_collection.delete_one（{'create_at'：fecha}）”此“ Tweets_collection.deleteone（{'create_at'：fecha'：fecha}）”
use it instead "tweets_collection.delete_one({'created_at':fecha})" this "tweets_collection.deleteOne({'created_at':fecha})"
