You should be aware that there are gotchas: while this workds fine

:categories_id_eq

If you want to find products in any category you can go with

:categories_id_in

But if you need to get products belonging to all of categories selected it wont work as expected:

:categories_id_all

returns zero results see discussions:

I think the field you're trying to use would be

:categories_id_eq

Usage would be something like this

<%= f.label :categories_id_eq, "Category" %>
<%= f.collection_select :categories_id_eq, Category.order(:title), :id, :title %>
