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:
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 50Managing your keys just became a lot less fragile.
Install it from pypi
$ pip install ok-redis
Access fields.
class User(ok.Key):
fields = ['timeline', 'followers', 'following']
print(User('mixxorz').timeline)
# User:mixxorz:timelineChain keys.
class City(ok.Key):
fields = ['tweets_hll']
class Country(ok.Key):
subkeys = [City]
print(Country('PH').City('Manila').tweets_hll)
# Country:PH:City:Manila:tweetsSubkeys can be an absolute or relative path to a key.
# 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:elementsThe string representation of a Key instance is the key, so you can use it like this:
class User(ok.Key):
pass
r.get(User('mixxorz'))But you can also access the key explicitly.
User('mixxorz').key
# >>> User:mixxorzIDs are optional.
class User(ok.Key):
fields = ['rankings']
print(User().rankings)
# User:rankingsIDs don't have to be strings
class User(ok.Key)
pass
print(User(123))
# User:123You can change the string used for the key.
class Facebook(ok.Key):
fields = ['all_posts']
class_key = 'fb'
print(Facebook().all_posts)
# fb:all_postsMIT
