Module: TimeRangeConcern

Extended by:
ActiveSupport::Concern
Included in:
RailsPulse::DashboardController
Defined in:
app/controllers/concerns/time_range_concern.rb

Overview

TimeRangeConcern

Handles time range selection and filtering across all controllers. Supports multiple time range sources with priority order:

  1. Page-specific preset/custom range (from dropdown/picker)

  2. Chart zoom parameters

  3. Time range selector (session)

  4. Global filters (session)

  5. Default time range

Normalizes times to beginning/end of hour or day based on range duration.
