python - pymongo : delete records elegantly

Question

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)})

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()

或者像从obj中删除

 obj.delete() or obj.remove()

或类似的？

您可以使用以下内容:

collection.remove({"date": {"$gt": "2012-12-15"}})
