我用的MongoDB和PyMongo工作,我想通過ID刪除行:bson.errors.InvalidId pymongo
_id = "c8c9447c42c82044be595b" #row id in database
result = database.collection.delete_one({"_id": ObjectId(_id)}) #delete one row with the given id
print(result.deleted_count) #1 true, 0 false
當我運行我的代碼,我得到了以下錯誤消息:
bson.errors.InvalidId: 'c8c9447c42c82044be595b' is not a valid ObjectId, it must be a 12-byte input or a 24-character hex string
我已經嘗試過我的ID轉換爲十六進制,但它沒有工作,還是同樣的錯誤
hexlify = codecs.getencoder('hex')
print(':'.join(hex(ord(x))[2:] for x in 'c8c9447c42c82044be595b'))
有什麼建議?
您是否嘗試先導入ObjectId?像 - 從bson.objectid導入ObjectId –
是的,我已經導入>>從bson import ObjectId – tamaramaria
