Re: [mongodb-user] convert pymongo Cursor to json

[Bernie Hackett]

from bson import json_util

The old pymongo.* aliases were removed in PyMongo 2.2 after being deprecated for about 2 years.

Hi, - I know this is a fairly common problem. I'm writing a small Flask app and I'm trying to feed some queries back to the view.

I've connected to my local MongoDB setup, and made a successful query - but I can't generate a json object with it. 

The most common solution I've seen is to import json_util from pymongo i.e. 

import json

from pymongo import json_util

results = connection.get_collection('papayas_papaya')

results = results.find({

    'identifier': '1',

})

serialized_results = [json.dumps(result, default=json_util.default, separators=(',', ':')) for result in results]

I've installed pymongo into my Flask virtualenv using pip i.e :

pip install pymongo

When running the above code I keep getting the following error:

ImportError: cannot import name json_util

I can see this line in the pymongo-2.3-py2.6.egg-info/installed-files.txt

../bson/json_util.py

Anyone got any tips that can help me figure out what I'm doing wrong?
