Record Author instead of Last Poster

[sobrenome]

In the categoryRow template, the default template shows the last poster (comments) of a database record:

 

{{if $lastPost}}
                <div class="ipsPhotoPanel ipsPhotoPanel_mini">
                    {template="userPhoto" app="core" group="global" params="$lastPost['author'], 'mini'"}
                        <div>
                            <ul class="ipsList_reset">
                            <li><a href="{$lastPost['record_url']}" class='ipsType_break ipsContained' title='{$lastPost['record_title']}'>{truncate="$lastPost['record_title']" length="65"}</a></li>
                            <li>{lang="byline_nodate" htmlsprintf="$lastPost['author']->link()"}</li>
                            <li data-short="1 dy" class="ipsType_light"><a href='{$lastPost['record_url']->setQueryString( 'do', 'getLastComment' )}' title='{lang="get_last_post"}' class='ipsType_blendLinks'>{datetime="$lastPost['date']"}</a></li>
                            </ul>
                        </div>
                </div>
             {{else}}
				 <ul class="ipsList_reset">
                 <li class='ipsType_light ipsResponsive_showDesktop'>{lang="content_categories_index_no_records" sprintf="\IPS\cms\Databases::load( $category->database_id )->recordWord()"}</li>
                 </ul>
             {{endif}}

Instead of last poster, I would like to show the record author.

How should be the code?

Thanks!
