Defined in:
lib/acta/web/events_query.rb

Overview

Builds the filtered Acta::Record scope that drives the event log admin UI. Extracted from EventsController so it can be unit-tested without a Rails-app fixture, and reused if other admin surfaces want the same filter semantics.

All filter values are user-supplied. String LIKE values are passed through ActiveRecord::Base.sanitize_sql_like to neutralise %/_ wildcards in user input.

FILTER_KEYS =

Names of params accepted; used by callers to build current-filter views and by tests to check the param surface.
