MongoDB Object Serialized as JSON

Question

I\'m attempting to send a JSON encoded MongoDB object back in my HTTP response. I\'ve followed several other similar questions but am still missing something. No exceptions

In newer versions of simplejson (and the json module in Python 2.7) you implement the default method in your subclasses:

from json import JSONEncoder
from pymongo.objectid import ObjectId

class MongoEncoder(JSONEncoder):
    def default(self, obj, **kwargs):
        if isinstance(obj, ObjectId):
            return str(obj)
        else:            
            return JSONEncoder.default(obj, **kwargs)

You could then use the encoder with MongoEncoder().encode(obj) or json.dumps(obj, cls=MongoEncoder).
