Class Method Details
.all_taxons ⇒ Object
Filtering by the list of all taxons
Similar idea as above, but we don’t want the descendants’ products, hence it uses one of the auto-generated scopes from Ransack.
idea: expand the format to allow nesting of labels?

.taxons_below(taxon) ⇒ Object
Provide filtering on the immediate children of a taxon
This doesn’t fit the pattern of the examples above, so there’s a few changes. Firstly, it uses an existing scope which was not built for filtering - and so has no need of a conditions mapping, and secondly, it has a mapping of name to the argument type expected by the other scope.
This technique is useful for filtering on objects (by passing ids) or with a scope that can be used directly (eg. testing only ever on a single property).
This scope selects products in any of the active taxons or their children.
