i2bskn/redis-helper

helper module for models using Redis

Redis::Helper

Redisを扱うクラスで利用するモジュール

Redis::Objectsがmulti使えないとかアレっていう @i2bskn さん等の想いのカケラ。

Installation

Add this line to your application's Gemfile:

gem "redis-helper"

And then execute:

$ bundle

Or install it yourself as:

$ gem install redis-helper

Usage

API Documents

class Foo < ActiveRecord::Base
  include Redis::Helper
  define_attr_keys :bar_count

  def bar_count
    # bar_count_key == attr_key(:bar_count) == "Foo:<id>:bar_count"
    redis.get(bar_count_key).to_i
  end

  def update_bar_count(count)
    # ttl_to(self.end_at) => self.end_at - Time.current
    redis.setex(bar_count_key, ttl_to(self.end_at), count)
  end
end

foo = Foo.find(id)
foo.update_bar_count(10)
foo.bar_count => 10
