Related Products

Related Products is a Spree Commerce extension that provides a generic way for you to define different types of relationships between your products, by defining a RelationType for each type of relationship you'd like to maintain.

You can manage RelationTypes via the admin configuration menu, and you can maintain product relationships via Related Products tab on the edit product UI.

Relation Types

When you create a RelationType you can access that set of related products by referencing the relation_type name, see below for an example:

rt = Spree::RelationType.create(name: 'Accessories', applies_to: 'Spree::Product')
 => #<Spree::RelationType id: 4, name: "Accessories" ...>
product = Spree::Product.last
 => #<Spree::Product id: 1060500592 ...>
product.accessories
 => []

Since respond_to? will not work in this case, you can test whether a relation_type method exists with has_related_products?(method):

product.has_related_products?('accessories')
# => true

if product.has_related_products?('accessories')
  # Display an accessories box..
end

You can access all related products regardless of RelationType by:

product.relations
 => []

Discounts You can optionally specify a discount amount to be applied if a customer purchases both products.

Note: In order for the coupon to be automatically applied, you must create a promotion leaving the code value empty, and adding an Action of type : RelatedProductDiscount (blank codes are required for coupons to be automatically applied).

Installation

Add this extension to your Gemfile with this line:

Spree >= 3.1

gem 'spree_related_products', github: 'spree-contrib/spree_related_products'

Spree 3.0 and Spree 2.x

gem 'spree_related_products', github: 'spree-contrib/spree_related_products', branch: 'X-X-stable'

The branch option is important: it must match the version of Spree you're using. For example, use 3-0-stable if you're using Spree 3-0-stable or any 3.0.x version.

Install the gem using Bundler:

bundle install

Copy & run migrations

bundle exec rails g spree_related_products:install

Restart your server

If your server was running, restart it so that it can find the assets properly.
