Redis datastore library

Radishsalad is simple lib for work with redis datastore in more pythonic way.

Base

It include String, Hash, List and Set classes, that represent redis datatypes. You need to initialize datatype with key:

>>> dt.List('main stream').append('Blogger Navalniy discovered new corruption scheme in Russia!')
1L
>>> list(dt.List('main stream'))
['Blogger Navalniy discovered new corruption scheme in Russia!']

>>> up = dt.Hash('0:user profile')
>>> up['name'] = 'deepwalker'
>>> dict(up)
{'name': 'deepwalker'}
>>> 'name' in up
True

>>> friends = dt.Set('friends')
>>> friends.add(1929340)
>>> set(friends)
set(['1929340'])
>>> 1929340 in friends
True

Models

Radishsalad has models module that is not positioned as Django ORM thing. Its just helper for keys name generation. So you create an model:

>>> from radishsalad import models as m
>>> class User(m.Model):
...      name = m.String()
...      subscribers = m.Set()
...      profile = m.Hash()
...      messages = m.List()
...      read = m.List()
...

And for using you need initialize it with key:

>>> user = User(1000)

Now you have user instance, and you can get keys for it members:

>>> user.name.get_key()
'user:1000:name'

Library does not return you a string instead of String objects for using in redis.mget:

>>> from radishsalad.connection import get_redis
>>> r = get_redis()
>>> r.mset(dict((User(i).name.get_key(), i) for i in xrange(40)))
>>> r.mget(User(i).name.get_key() for i in xrange(40))
['0', '1', '2', '3', '4', '5', '6', '7', ... '38', '39']
