A navigable is an application document that includes the Workarea::Navigable module, and thereby has a slug attribute and a 1:1 relationship with a taxon.


A navigable has a slug attribute, which is a unique, human- and URL-friendly string used to identify the model, particularly when requesting the model via a URL.

For example, in the Storefront, the path /pages/foo is routed to Storefront::PagesController#show, which looks up the requested page by slug:

Content::Page.find_by(slug: params[:id])

Calling to_param on a navigable returns the navigable's slug, allowing idiomatic use of Rail's routing helpers, while maintaining "pretty" URLs.

= page_path(@page)
/ evaluates to "/pages/foo"

A navigable must have a slug, but one will be generated if not provided explicitly. A generated slug is derived from the navigable's name, including an incrementing suffix if needed to ensure uniqueness.

Workarea::Catalog::Category.create!(name: 'Foo').slug
# => "foo"

Workarea::Catalog::Category.create!(name: 'Foo').slug
# => "foo-1"


A navigable has a 1:1 relationship with a taxon, which represents the navigable's position within the site's taxonomy tree.

navigable = Workarea::Catalog::Product.create!(name: 'Foo')
taxon = Workarea::Navigation::Taxon.create!(navigable: navigable)

# => Workarea::Navigation::Taxon
# => "Foo"
