Overview

OwnerResolver Builds the owners: option the klass entities read, so rendering a grid of N templates costs one user query instead of N. Deleted users are included on purpose: a template whose author has left still has to name somebody, otherwise the grid can only say "unknown" and an administrator has nothing to act on.

Class Method Details

.find(user_id) ⇒ Object

Single-user fallback for the call sites that ask for ownership without preloading a map. Same soft-delete scope and same "never break the caller" contract as map_for.

  map_for_ids(Array(klasses).filter_map { |klass| klass.try(:created_by) })
end

.map_for_ids(ids) ⇒ Object

Same map, from bare user ids — what ShareResolver feeds it, where the ids come from owner share rows rather than a created_by column.
