Create a product which is composed of other products.
Add the following line to your Gemfile
gem "spree_product_assembly", github: "spree/spree-product-assembly"
ps. Note current master branch is stable enough and tested against spree/spree 2-0-stable
Run bundle install as well as the extension intall command to copy and run migrations and append spree_product_assembly to your js manifest file
bundle install
rails g spree_product_assembly:install
Use 1-3-stable branch for Spree 1.3.x compatibility
In case you're upgrading from 1-3-stable of this extension you might want to run a rake task which assigns a line item to your previous inventory units from bundle products. That is so you have a better view on the current backend UI and avoid exceptions. No need to run this task if you're not upgrading from product assembly 1-3-stable
rake spree_product_assembly:upgrade
To build a bundle (assembly product) you'd need to first check the "Can be part" flag on each product you want to be part of the bundle. Then create a product and add parts to it. By doing that you're making that product an assembly.
The store will treat assemblies a bit different than regular products on checkout. Spree will create and track inventory units for its parts rather than for the product itself. That means you essentially have a product composed of other products. From a customer perspective it's like they are paying a single amount for a collection of products.
