MongoDB Object DataBase (MODB) for Python objects
Project description
Overview
jaraco.modb is a small, pure-Python library for persisting Python objects to MongoDB.
jaraco.modb is written by Jason R. Coombs. It is licensed under an MIT-style permissive license.
You can install it with easy_install jaraco.modb or grab the source code from the mercurial repository.
Usage
jaraco.modb facilitates using jsonpickle to produce MongoDB-friendly representations of pickleable Python objects for easy storage in a MongoDB database.
One may simply encode and decode Python objects to MongoDB BSON-friendly representations:
class MyObject(object):
def __init__(self, val):
self.val = val
import jaraco.modb
import pymongo
mongo_collection = pymongo.Connection().mydb.mycollection
val = MyObject(3)
# save the object to the DB
id = mongo_collection.save(jaraco.modb.encode(val))
# retrieve the object from the DB
new_val = jaraco.modb.decode(mongo_collection.find_one(id))
assert isinstance(new_val, MyObject)
assert new_val.val == 3
Changes
1.2
Now store naive and UTC datetimes naturally in MongoDB.
The encoder/decoder now subclasses the jsonpickle classes to more efficiently handle binary strings.
1.1
Added proper support for datetime objects.
Added support for OrderedDictionaries.
