How do I auto generate products via attribute? I have a shoe store, as you know, Drupal Commerce allow us to control each Attribute of Shoe like Color and Size.

This is my problem :

I have 2000 shoe styles, each style has sizes from 5-12 (6US to 12US)
It mean that everytime I add new style, I have to create 8 products for 8 sizes. Im using Clone Product Module, it's working very well, but how can I save my time :

It mean that when I create New Shoe Style (Node Products Display)
--> node/add/shoe-style
--> the system will auto generate 8 products (Size) for me, it depend on how many value in my attribute field (Size attribute has 8 value and system will create 8 new product), and now what we need to do is update something to each product.
Assuming you are using Drupal 7, you've got a couple of options:


Commerce Migrate will let you create products as part of a migration. It's a bit more time consuming but it's repeatable and is very powerful.
You can use Commerce Bulk Product Creation to create products based off of fields in the UI. This gives the ability to create those products once and isn't repeatable.
