A lightweight, flexible key generator for NoSQL / Key-Value stores, such as Redis, Memcached, Riak, Tokyo Cabinet, etc.

Examples

class User
  include Kiki

  cache_key :redis

  cache_key :memcached,
            :domain     => 'people',
            :delimiter  => '/',
            :identifier => :username
end

User.redis_key                  # => #<Keytar::Key:0x000001008ea9a8 @namespace="redis", @delimitter=":", @domain="users", @identifier=:id>
User.redis_key("count")         # => redis:users:count
User.find(1).redis_key          # => redis:users:1
User.find(1).redis_key("items") # => redis:users:1:items

User.find(1).memcached_key      # => memcached/people/schneems

# Configuration can be done on the key object
User.memcached_key.identifier = :email
User.find(1).memcached_key      # => memcached/people/mistersnowman@example.com

Configuration

namespace

the first argument for cache_key, the instance and class method [namespace]_key will be added, which generate keys prefixed by the namespace (eg. “redis” would add the method “redis_key”, generating a key like “redis:users:1”)

domain

optional, defaults to the downcase, pluralized name of your class (eg. “class User” would have the domain “users”)

delimiter

optional, defaults to “:”

identifier

this is the method that is sent when calling “*_key” on an instance, or passing non-string / non-numeric arguments into a “*_key” method. optional, defaults to “:id”

Credit

This project was inspired by [Richard Schneeman](github.com/schneems/)‘s awesome library [Keytar](github.com/schneems/keytar/). Essentially, this my alternative take on the problem, focusing on simplicity of API and implementation.
