ruby-on-rails - Spree grab all products for taxon and children taxons

Question

I basically want to grab the following in a view:

All the products for the current taxon, and then all the products for the taxon's children. What's the best way to do this? Is there a method already?

Answer 1

taxon_products = current_taxon.products
children_products = current_taxon.children.includes(:products).map(&:products).
                                  flatten.compact.uniq

Answer 2

如果您只需要搜索一个级别的孩子，@PinnyM 的答案很好，但是如果您想找到一个分类单元下的所有产品，您可以使用这样的in_taxon范围：

children_products = Spree::Product.in_taxon(current_taxon)
