convert pymongo Cursor to json

[marcus kielly]

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?

from bson import json_util

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