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: miq_request_workflow.rb
    path of file: ./repos/manageiq/app/models
    
    the code of the file until where you have to start completion: require 'ostruct'

class MiqRequestWorkflow
  include Vmdb::Logging
  includ
    
  def make_request(request, values, _requester = nil, auto_approve = false)
    return false unless validate(values)

    password_helper(values, true)
    # Ensure that tags selected in the pre-dialog get applied to the request
    values[:vm_tags] = (Array.wrap(values[:vm_tags]) + @values[:pre_dialog_vm_tags]).uniq if @values.try(:[], :pre_dialog_vm_tags).present?

    set_request_values(values)
    if request
      MiqRequest.update_request(request, values, @requester)
    else
      req = request_class.new(:options => values, :requester => @requester, :request_type => request_type.to_s)
      return req unless req.valid? # TODO: CatalogController#atomic_req_submit is the only one that enumerates over the errors

      values[:__request_type__] = request_type.to_s.presence # Pass this along to MiqRequest#create_request
      request_class.create_request(values, @requester, auto_approve)
    end
