Path alias tokens and node references
I'm having some difficulties setting up url patterns for my drupal project.
The site has 3 different content types, Main category, sub category and products. All of these are linked together by entity references.
So a sub category is linked to a main category, and a product is linked to a sub category. But now I want my urls to look like: main_category/sub_category/product Or for a sub category it should look like: main_category/product
How would I be able to achieve this? I've installed path auto, but can't seem to figure it out.
EDIT: And another question would be, what would be the easiest way to create a menu out of this?
