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: hosts_and_hostgroups_helper.rb
    path of file: ./repos/foreman/app/helpers
    
    the code of the file until where you have to start completion: module HostsAndHostgroupsHelper
  include AncestryHelper

  def domain_subnets(type)
    accessible_related_resource(@domain, :subnets, :where => {:type => type})
  end

  def arch_oss
    accessible_related_resource(@architecture, :operatingsystems, order: :title)
  end

  def os_m
    
  def multiple_filter(hosts)
    return unless multiple_with_filter?
    host_count = hosts.size
    no_filter = n_("Reminder: <strong> One host is selected </strong>",
      "Reminder: <strong> All %{count} hosts are selected </strong>", host_count).html_safe % {count: host_count}
    with_filter = n_("Reminder: <strong> One host is selected </strong> for query filter %{query}",
      "Reminder: <strong> All %{count} hosts are selected </strong> for query filter %{query}", host_count).html_safe % {count: host_count, query: h(params[:search]) }
    params[:search].blank? ? no_filter : with_filter
