You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: reports_controller.rb
    path of file: ./repos/osem/app/controllers/admin
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Admin
  class ReportsController < Admin::BaseController
    load_and_authorize_resource :conference, find_by: :short_title
    load_and_authorize_resource :program, through: :conference, singleton: true
    # For some reason this doesn't work, so a workaround is used
    # load_and_authorize_resource :event, through: :program

    def index
      @events = Event.accessible_by(current_ability).where(program: @program)
      @events_commercials = Commercial.where(commercialable_type: 'Event', commer
    
    def index
      @events = Event.accessible_by(current_ability).where(program: @program)
      @events_commercials = Commercial.where(commercialable_type: 'Event', commercialable_id: @events.pluck(:id))
      @events_missing_commercial = @events.where.not(id: @events_commercials.pluck(:commercialable_id))
      @events_with_requirements = @events.where.not(description: ['', nil])

      attended_registrants_ids = @conference.registrations.where(attended: true).pluck(:user_id)
      @missing_event_speakers = EventUser.joins(:event)
                                .where('event_role = ? and program_id = ?', 'speaker', @program.id)
                                .where.not(user_id: attended_registrants_ids)
                                .where(event_id: @events.pluck(:id))
                                .includes(:user, :event)
