Pymongo导入成功但未在集合中显示

Question

我尝试导入成功的json文件

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

但是当我尝试查看时，它不存在

from pymongo import MongoClient

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

它没有显示任何内容

Answer 1

问题在于：

db.coll.find()

这会找到 coll集合中的所有文档，但您的集合名为dbcol 。

相反，请使用您已定义的coll变量：

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)
