Object-Key Mapper for Redis

If you’ve used redis on python, you’ve had to deal with redis keys.

Sometimes, *lots* of redis keys. With so many keys, it’s easy to make

mistakes, especially since keys are just strings. I built ``ok`` so that

I didn’t have to work with strings for redis keys.

Here’s how you use it:

.. code:: python

    import ok

    import redis

    class User(ok.Key):

        fields = ['timeline', 'followers', 'following']

    # Get user mixxorz' timeline

    r = redis.StrictRedis()

    r.zrevrange(User('mixxorz').timeline, 0, 50)

    # ZREVRANGE User:mixxorz:timeline 0 50

Managing your keys just became a lot less fragile.

Installation

------------

Install it from pypi

::

    $ pip install ok-redis

Usage

-----

Access fields.

.. code:: python

    class User(ok.Key):

        fields = ['timeline', 'followers', 'following']

    print(User('mixxorz').timeline)

    # User:mixxorz:timeline

Chain keys.

.. code:: python

    class City(ok.Key):

        fields = ['tweets_hll']

    class Country(ok.Key):

        subkeys = [City]

    print(Country('PH').City('Manila').tweets_hll)

    # Country:PH:City:Manila:tweets

Subkeys can be an absolute or relative path to a key.

.. code:: python

    # mod_one.py

    class Refer(Key):

        fields = ['elements']

    # mod_two.py

    class Parent(Key):

        subkeys = ['..mod_one.Refer']

    print(Parent('foo').Refer('bar').elements)

    # Parent:foo:Refer:bar:elements

The string representation of a `Key` instance is the key, so you can use it like

this:

.. code:: python

    class User(ok.Key):

        pass

    r.get(User('mixxorz'))

But you can also access the key explicitly.

.. code:: python

    User('mixxorz').key

    # >>> User:mixxorz

IDs are optional.

.. code:: python

    class User(ok.Key):

        fields = ['rankings']

    print(User().rankings)

    # User:rankings

IDs don't have to be strings

.. code:: python

    class User(ok.Key)

        pass

    print(User(123))

    # User:123

You can change the string used for the key.

.. code:: python

    class Facebook(ok.Key):

        fields = ['all_posts']

        class_key = 'fb'

    print(Facebook().all_posts)

    # fb:all_posts
