Priceable

Easily manage prices in your Rails application

Installation

Add this line to your application's Gemfile:

gem 'priceable'

And then execute:

$ bundle

Say you have a model, Llama. You can buy Llamas for a cost. Let's add the cost to the Llama model.

$ rails g migration add_cost_to_llamas cost_in_cents:integer
$ rake db:migrate

Now we just need to tell Rails that the cost field is priceable

# app/models/llama.rb

class Llama < ActiveRecord::Base
  priceable :cost
end

And now lets check it out in the console

>> llama = Llama.last
>> llama.cost # => nil
>> llama.cost = 100
>> llama.cost_in_cents # => 10000
>> llama.cost # => 100

Isn't that special. So go, and add prices easily to your models, with Priceable.

PS: priceable can take more than one field at a time, so go ahead and load it up like a baked potato.

priceable :retail_price, :employee_price, :cost
