Activator

Ever needed to mark a record as active in your application while all the other records are inactive? Activator is the gem you need.

How to use?

Setup

For now, the gem only works with one field, namely active. To use the gem, simply include the module Activator.

class Object < ActiveRecord::Base
  include Activator
end

Note that when you don't add this, all the extra methods won't be available.

Usage

Once you mark one object as active, the others will get deactivated.

first = Object.create(:active => true)
first.active # true

second = Object.create(:active => true)
second.active # true
first.active # false

first.update_attributes(:active => true)
first.active # true
second.active #false

Activator field

There's an option to set the field which activator applies to. By default this will be the active field.

To use another field, you can use the activator_field option.

class Object
  include Activator
  activator_field :default
end

This will make Object.default available instead of Object.active to get your

in this case - default field.

object = Object.create(default: true)
Object.default # object

Available methods

Object#activator_deactivate!

Deactivate a single object. This will simply set the activator field to false.

Object.active

Get the current active object. This will only fetch one result as you should only have one active object at a time.

Note: this method name will change if you use the activator_field option.
