Included in:
Api::Partner::AttachmentSerializer, PartnerService::Reservations::Exports::ProgressTracker, PartnerService::Reservations::Exports::TrackingService, ReservationExportHelpers
Defined in:
app/workers/concerns/export_constants.rb

Overview

Constants for export operations to avoid hard-coded values throughout the codebase. This module centralizes all configuration values used in export workers and services.

Examples:

Usage in worker

class MyExportWorker < ApplicationWorker
  include ExportConstants

  def perform
    update_progress(PROGRESS_PHASES[:collecting_data].first, 'Starting data collection...')
    reservations.find_in_batches(batch_size: RESERVATION_BATCH_SIZE) do |batch|
      # Process batch
    end
  end
end
