pymongo : delete records elegantly
提问by icn
Here is my code to delete a bunch of records using pymongo
这是我使用 pymongo 删除一堆记录的代码
ids = []
with MongoClient(MONGODB_HOST) as connection:
db = connection[MONGODB_NAME]
collection = db[MONGODN_COLLECTION]
for obj in collection.find({"date": {"$gt": "2012-12-15"}}):
ids.append(obj["_id"])
for id in ids:
print id
collection.remove({"_id":ObjectId(id)})
IS there a better way to delete these records? like delete a whole set of records directly
有没有更好的方法来删除这些记录？比如直接删除一整套记录
collection.find({"date": {"$gt": "2012-12-15"}}).delete() or remove()
or delete from obj like
或从 obj 中删除
obj.delete() or obj.remove()
or somehting similar?
或类似的东西？

You can use the following:
您可以使用以下内容：
collection.remove({"date": {"$gt": "2012-12-15"}})

For now collection.remove(filter)is deprecated, use collection.delete_many(filter).
目前collection.remove(filter)已弃用，请使用collection.delete_many(filter).
Example: collection.delete_many({"author": ObjectId("...")})
例子： collection.delete_many({"author": ObjectId("...")})
