python - 使用 pymongo 将数组插入 mongodb

Question

我正在尝试使用 pymongo 将数组添加到 mongdb

我有另一个程序会返回类似的内容

['1 aksdfjas;dkfjsa;dfkj','2 ;alksdjf;askdjf;asdfjkasdf', '3 ;alksdfj;asdlkfj;asdfj']

我想将它们添加到插入中。

1)我想不出任何其他方法来做到这一点，所以我将它们转换为字符串并连接并尝试将它们添加到帖子中(一定有更好的方法吗？)

2)当我这样做时，我得到的不是欲望影响，而是

["'1 aksdfjas;dkfjsa;dfkj','2 ;alksdjf;askdjf;asdfjkasdf', '3 ;alksdfj;asdlkfj;asdfj'",]

额外的引号..我该如何纠正这个问题？

import pymongo
import time
import datetime
from random import *
from pymongo import MongoClient


client = MongoClient('mongodb://user:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="147576772526275425243a243a243a25" rel="noreferrer noopener nofollow">[email protected]</a>:27017')

stringToStuff = 'blabh blah blahhhhh'

def createLoop():
    return randint(5,15)

def tGenerator(e):
    returnString = '' 
    for i in range(e):
        returnString +=  "'" + str(i+1) + " " + stringToStuff + "',"
    return returnString

db = client['pytest']
collection = db['test']
names = db.test.find()

collection2 = db['pytestResult']
for p in names:
    print(p['name'])
    name2 = p['name'] 

    #post = {"name":name2,"score":8,"date":datetime.datetime.now()}
    post = {
        "name":name2,
        "score":8,
        "date":datetime.datetime.now(),
        #”output”: ['1 aksdfjas;dkfjsa;dfkj','2 ;alksdjf;askdjf;asdfjkasdf', '3 ;alksdfj;asdlkfj;asdfj',]
        “output”: [tGenerator(createLoop())]
    }
    collection2.insert_one(post)

Answer 1

首先，将 tGenerator 方法构建字符串的方式更改为以下内容:

returnString += str(i+1) + " " + stringToStuff + ","

其次，您可以使用 split 方法来执行所需的操作，因此您的插入将如下所示:

post = {
    "name":name2,
    "score":8,
    "date":datetime.datetime.now(),
    "output": tGenerator(createLoop()).split(',')
}
collection2.insert_one(post)

希望以上内容对您有用。
