Constant Summary collapse

ATTRIBUTES =

Params exists for all CollectingEvent attributes except these. geographic_area_id is excluded because we handle it specially in conjunction with `geographic_area_mode“ Definition must preceed include.

(::CollectingEvent.core_attributes - %w{geographic_area_id} + %w(cached_level0_geographic_name cached_level1_geographic_name cached_level2_geographic_name)).map(&:to_sym).freeze
BASE_PARAMS =

This list of params are those that only occur in this CollectingEvent filter. For those that overlap other filters place in PARAMS.

Used to define a base collecting query for CollectionObject filters scope, this is still used in CollectionObject query. This is “necessary” so that we can use CollectingEvent referencing facets in the CollectionObject filter for convienience.
