The rails way to develop a multi product type shopping cart

Rails
1

Hi,

I’m developing an application which has to manage many types of
products.
But I can’t think what the best approach in rails is on how to implement
them. Here is a selection of some of the products (with some data types)
that the software will have to manage:
Speaker
Make - String
Model - String
Wattage - Integer
Price - Decimal

Light
  Make - String
  Model - String
  Wattage - Integer
  Price - Decimal

Microphone
  Make - String
  Model - String
  Use - Choice of: Instrumental, Vocal, Versatile
  Price - Decimal

Cable
  Length - Decimal
  Connector 1 - String
  Connector 2 - String
  Price - Decimal

Stand
  Type - Choice of: Microphone, Speaker
  Height - Decimal
  Boom - Boolean
  Price - Decimal

Ways I have thought about the design:

  • An individual model for each type of product then a polymorphic
    association in the cart so that it can handle all the types of
    equipment.
  • A single product model that has fields for all types of equipment
    with
    a type field which can be checked when ever the product is used.
  • A product model with a price attribute then every type of product
    extends that model.

But what is the best way in rails to handle these different types of
products?

TIA,

Dean
