Flavors

Simple and flexible preferences integration for ActiveRecord models.

Add this line to your application's Gemfile:

gem 'flavors'

And then execute:

$ bundle

Or install it yourself as:

$ gem install flavors

Generate the migration for the preferences table and migrate the database:

$ rails generate flavors:migration
$ rake db:migrate

To add preferences to your ActiveRecord model, in your model file:

class User < ActiveRecord::Base
  preference :receive_email, default: true
end

Then you can then use the methods provided by flavors to read / write preferences.

irb(main):001:0> u = User.create(email: "foo@bar.com")
irb(main):002:0> u.notification
=> true
irb(main):003:0> u.notification = false
=> false
irb(main):004:0> u.notification
=> false

From 0.2.0, Flavors also supports callback block for preference setter.

class User < ActiveRecord::Base
  preference :receive_email, default: true do |object, value|
    puts "#{object.name} sets preference to #{value}"
  end
end

When you set preference of instances, the callback block will be invoked.

irb(main):001:0> u = User.create(name: "foo", email: "foo@bar.com")
irb(main):002:0> u.notification = true
foo sets preference to true
=> true
