# 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](https://github.com/i2bskn) さん等の想いのカケラ。

## Installation

Add this line to your application's Gemfile:

```ruby
gem "redis-helper"
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install redis-helper

## Usage

```ruby
class Foo < ActiveRecord::Base
  include Redis::Helper

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

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

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