Pymongo 导入成功但未显示在集合中 [英] Pymongo importing succeeded but not showing in the collection

问题描述

我尝试导入成功的 json 文件

mongoimport --db dbwhy --collection dbcol --jsonArray consumer_complaint.json2016-01-15T19:00:42.277-0600 连接到:本地主机2016-01-15T19:00:42.320-0600 导入 34 个文件

但是当我尝试查看它时，它不在那里

from pymongo import MongoClient客户端 = MongoClient('本地主机',27017)db = 客户端['dbwhy']coll = db['dbcol']诅咒 = db.coll.find()因为我在curs中:打印(一)

它没有显示任何东西

解决方案

问题出在这里:

db.coll.find()

这将找到 coll 集合中的所有文档，但您的集合名为 dbcol.>

相反，使用您已经定义的 coll 变量:

from pymongo import MongoClient客户端 = MongoClient('本地主机',27017)db = 客户端['dbwhy']coll = db['dbcol']curs = coll.find() # FIX 在这里因为我在curs中:打印(一)

I tried importing json file which succeeded

mongoimport --db dbwhy --collection dbcol --jsonArray consumer_complaint.json
2016-01-15T19:00:42.277-0600    connected to: localhost
2016-01-15T19:00:42.320-0600    imported 34 documents

but when I tried viewing it, it was not there

from pymongo import MongoClient

client = MongoClient('localhost',27017)
db = client['dbwhy']
coll = db['dbcol']
curs = db.coll.find()
for i in curs:
    print(i)

It does not show anything

解决方案

The problem is here:

db.coll.find()

This would find all documents inside the coll collection, but your collection is named dbcol.

Instead, use the coll variable that you've already defined:

from pymongo import MongoClient

client = MongoClient('localhost',27017)

db = client['dbwhy']
coll = db['dbcol']

curs = coll.find()  # FIX is here
for i in curs:
    print(i)
