Spree: Customize Key Product Attributes

Question

Does anyone know if it is possible to add a new attribute to a set of key attributes (name, description, permalink, description of metadata, etc.) of a product? The idea is that I want these attributes to be available when I create the product, and not add it later through Product Properties.

Thanks.

Answer 1

The easiest way is to add attributes directly to the product model through migration. Ratings can be added using decorators, the preferred template in Spree to override models.

# in app/models/product_decorator.rb Product.class_eval do validates :some_field, :presence => true end 

Another option is to create a secondary model for your extended fields. Maybe ProductExtension

 # in app/models/product_extension.rb class ProductExtension < ActiveRecord::Base belongs_to :product validates :some_field, :presence => true end # in app/models/product_decorator.rb Product.class_eval do has_one :product_extension accepts_nested_attributes_for :product_extension delegate :some_field, :to => :product_extension end 

Then, in the product creation forms, you can provide these fields from field_to_. I think one caveat to this is that you will need to create a created product model before the extension becomes usable. Perhaps you will get around this with additional logic in the product controllers, create an action.

My way to extend the product model for Spree (via delegate_belongs_to):

 #app/models/product_decorator.rb Spree::Product.class_eval do has_one :product_extension accepts_nested_attributes_for :product_extension, :allow_destroy => true delegate_belongs_to :product_extension, :some_field attr_accessible :some_field end #app/models/product_extension.rb class ProductExtension < ActiveRecord::Base belongs_to :product, :class_name => 'Spree::Product' attr_accessible :some_field end
