I'm a new Odoo developer and I'm working for a shoe company with the goal of use Odoo for all business processes.

Since it’s a wholesale company, shoes can be sold in different colors and different packages.

The company has a list of pack codes to identify the package type, in particular to identify how many pair of shoes per size there are in a package.

Usually shoes are sold in 2 or 3 different package options.

I like the Odoo product attributes because are easy to use and Odoo generates all variants properly.

I created the pack model (a.k.a. size run) but using the product attributes I’m not able to link the pack code to the model that I created.

Note: I'm using version Odoo v10.
