Module: Spree::Core::ProductFilters
- Included in:
- Taxon
- Defined in:
- lib/spree/core/product_filters.rb
Overview
This module is included by Taxon. In development mode that inclusion does not happen until Taxon class is loaded. Ensure that Taxon class is loaded before you try something like Product.price_range_any
Class Method Summary collapse

.taxons_below(taxon) ⇒ Object
Provide filtering on the immediate children of a taxon.
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.
