Overview

A Catalog::Entry that contains the biological history of an otu via associated data of that otu (images, asserted distributions, observations, etc.).

Constructor Details

#initialize(otu, include_belongs_to: false) ⇒ InventoryEntry

nomenclature catalog typically handles citations on taxon_name, so by default we don’t process belongs_to relations on otu.

Instance Method Details

#add_rendering_includes(citation_query, relation_klass) ⇒ Object (private)

Eager load citation associations and the cited object for views. (We’re unfortunately tied to views since catalog is essentially a rendering tool.)
