Mnj (Mongo Energy) is a helper library to simplify PyMongo interaction
Untill Mnj release will be available via PyPI you may get somewhat ready to use snapshot via
pip install --pre mnj
or clone this repository to get the latest source and invoke install
python setup.py install
- Using
mnj.MongoClientwill setOrderedDictinstead ofdictas document class by default. - Using
mnj.qobject for constructing queries will help to validate them. - No creepy
'$op'strings any more use_op()frommnj.operators.
- More precise query validation including query structure and data types.
- Schema validation.
- See todo.txt for more.
Basic usage. Try yourself via python -m mnj.
from mnj.base import MongoClient
from mnj.operators import *
from mnj.query import q, Doc
db = MongoClient()['test']
db.docs.drop()
db.docs.insert(Doc([('a', 1), ('b', 1)]))
db.docs.insert(Doc([('a', 2), ('b', 2)]))
db.docs.insert(Doc([('a', 3), ('b', 3)]))
db.docs.insert(Doc([('a', 1), ('b', 4)]))
db.docs.insert(Doc([('a', 2), ('b', 5)]))
db.docs.insert(Doc([('a', 3), ('b', 6)]))
# {'a': 1, 'b': 1}
# {'a': 1, 'b': 4}
db.docs.find(q(a=1))
# {'a': 1, 'b': 1}
# {'a': 3, 'b': 3}
# {'a': 1, 'b': 4}
# {'a': 3, 'b': 6}
db.docs.find(q(a=_ne(2)))
# {'a': 1, 'b': 4}
# {'a': 2, 'b': 5}
# {'a': 3, 'b': 6}
for doc in db.docs.find(q(b=_gt(3)))
# {'a': 2, 'b': 2}
# {'a': 3, 'b': 3}
# {'a': 3, 'b': 6}
for doc in db.docs.find(q(a=3) | q(b=2))
# {'a': 1, 'b': 4}
for doc in db.docs.find(_and(q(a=1), q(b=4)))
