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
2.0
Removed initializer function (jaraco.modb.init()). Clients should remove that call (if present) before upgrading to 2.0.
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.
1.0.4
Removed requirement to call jaraco.modb.init() to initialize.
1.0
