【问题描述】:
我是 pymongo 和 mongodb 的新手。我正在尝试使用 pymongo 以交互方式插入文档。当我通过 python 脚本尝试文档时,它失败了。
输入名称: 测试3
输入地址:Someaddress
输入电话号码:9876543
{"Name": "test3", "Phone": 9876543, "Address": "Someaddress"} # Here I am printing the document to be inserted
Traceback (most recent call last):
File "./sample.py", line 54, in <module>
insertDocument()
File "./sample.py", line 27, in insertDocument
insert_id=db.collection.insert_one(obj)
File "/appl/swinstall/mongo-python-driver-master/pymongo/collection.py", line 676, in insert_one
common.validate_is_document_type("document", document)
File "/appl/swinstall/mongo-python-driver-master/pymongo/common.py", line 434, in validate_is_document_type
"collections.MutableMapping" % (option,))
TypeError: document must be an instance of dict, bson.son.SON, bson.raw_bson.RawBSONDocument, or a type that inherits from collections.MutableMapping
下面是我的代码:
#!/usr/bin/python
import sys
import os
from pymongo import MongoClient
ch=MongoClient()
db=ch.local
def insertDocument():
print "insertDocument"
print "Enter the name:"
name=raw_input(">> ")
print "Enter the address"
address=raw_input(">> ")
print "Enter the phone number"
phone=raw_input(">> ")
obj='{"Name": "'+ str(name) +'", "Phone": '+ str(phone) +', "Address": "'+ str(address) +'"}'
print obj
insert_id=db.collection.insert_one(obj)
insertDocument()
但是当我在 python 终端中尝试相同的操作时,它会被插入。
test={"Name":"Test3", "Phone":98765653, "Address":"SomeAddress"}
insert_id=db.collection.insert_one(test)
x=db.collection.find()
x.count()
5
for y in x:
... print y
...

有人可以帮忙吗?
【问题讨论】:
-
db.collection.insert_one('obj')您正在传递要插入的字符串obj。插入参数必须是dict。删除obj周围的引号。 -
感谢您的回复。删除了单引号。还是错误。 {"Name": "test4", "Phone": 9864362, "Address": "someaddr"} Traceback(最近一次调用最后):文件“./sample.py”,第 54 行,在

obj值是字符串,应该是dict! -
obj='...'# 这就是问题所在
