RedisField

RedisField is a simple Ruby gem that stores model-specific data to Redis just like normal ActiveRecord attributes.

Great for caches, API responses etc.

Installation

You will need ActiveRecord 3.2+ (oops, gotta test it).

Add this line to your application's Gemfile:

  gem 'redis_field', github: 'konukhov/redis_field'

And then execute:

$ bundle

Usage

1. Specify field names in your model

  class User < ActiveRecord::Base
    redis_field :some_data

    # redis_fields is just an alias to redis_field
    redis_fields :facebook_friend_ids, :last_logged_in
  end

2. Use these fields just like normal AR attributes

  user = User.last

  user.some_data = "Testing redis_field"
  user.save
  user.reload.some_data # -> "Testing redis_field"

  user.update_attributes(last_logged_in: Time.now)
  user.reload.last_logged_in # -> 2014-04-05 01:00:00 +0000

NB This library is not an ORM for Redis, so it simply marshalls data before storing to Redis. There's no types coercion or anything like that.

More docs and features soon. :heart:

Testing

Just run

$ rake spec

See Appraisal for testing against different ActiveRecord versions.
