RedisBackend

On the vein of the simplest-possible yet-functional Gem you could possibly release, this is a convenient way to "wrap" your Redis calls on a block that will be gracefully ignored if there is no database connection established yet:

module Collectable
  extend RedisBackend

  def self.ready_to_collect?
    available?  # $redis global variable holds the Redis DB connection
  end

  def self.all(which)
    backend do |redis|
      redis.smembers(which)
    end
  end
end

All you need to do is set the environment variables REDIS_SERVER and REDIS_AUTH (optional) to the host and the password required to execute any command.

Add this line to your application's Gemfile:

gem 'redis_backend'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redis_backend

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request
