Object-Relational Mapping (ORM)

Tentacles is a python ORM. The main idea is to manipulate stored datas as you do for python data structures

python native:

>>> class SuperHero(object):
>>>             def __init__(self, name, gender, power):
>>>                     self.name   = name
>>>                     self.gender = gender
>>>                     self.power  = power
>>>
>>> hero1 = SuperHero('superman', 'male', 'flight')
>>> print "%s can %s" % (hero1.name, hero1.power)

… vs tentacles …:

>>> from tentacles        import Object
>>> from tentacles.fields import *
>>> class SuperHero(Object):
>>>     name   = String()
>>>     gender = String()
>>>     power  = String()
>>>
>>> hero1 = SuperHero(name='superman', gender='male', power='flight')
>>> print "%s can %s" % (hero1.name, hero1.power)

python native:

>>> heros   = [hero1, SuperHero(name='wonder woman', gender='female', power='enhanced vision')]
>>> females = filter(lambda e: e.gender = 'female', heros)
>>> for e in females:
>>>     print "superheroine: %s" % e.name

… vs tentacles …:

>>> hero1.save(); SuperHero(name='wonder woman', gender='female', power='enhanced vision').save()
>>> females = filter(lambda e: e.gender = 'female', heros)
>>> for e in females:
>>>     print "superheroine: %s" % e.name

Tentacles is pretty yound and incomplete, and still in alpha stage. It currently support only sqlite3 backend, while more are scheduled at mid-term (mysql, postgresql, but also no-sql storages, like openldap, mongodb, …)
