Link an attachment of a knowledge base entry via an ADT

New Member Posts: 8 Join Date: 12/6/19 Recent Posts

Hello there,
i'm currently writing an ADT to customize the knowledge base style. I'm working with Liferay Portal 7.2.1 CE GA2. As there is not a dedicated ADT version for the knowledge base, i have to use the asset publisher modul and configure it to use only knowledge base assets and to use my custome ADT.
Some of the entries will have a PDF attachment. In the display of these knowledge base entires i would like to link these attachments. There is no obvious link between an knowledge base entry and it's attachment that i can use in an ADT or at least not obvious for me. emoticon

Thanks for any tips or help you can give.
Niels

Hi ,
You can use service locator and use KBArticleLocalservice for fetching the KBArticle and its attachments, you can refer below code snippet

&lt;#assign kbArticleLocalService = serviceLocator.findService("com.liferay.knowledge.base.service.KBArticleLocalService") /&gt;&nbsp;
&lt;#if entries?has_content&gt;
&nbsp;&nbsp; &nbsp;&lt;#list entries as curEntry&gt;
&nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&lt;#assign kbArticle = kbArticleLocalService.getLatestKBArticle(curEntry.getClassPK(), 0)&gt;&nbsp;
&nbsp; &nbsp; &nbsp; &nbsp; &lt;#assign kbAttachments = kbArticle.getAttachmentsFileEntries()&gt;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;
&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&lt;#if kbAttachments?has_content&gt;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&lt;#list kbAttachments as kbAttachment&gt;
&nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; &nbsp;${kbAttachment}&nbsp;&nbsp; &nbsp;
&nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp;<!--#list-->
&nbsp; &nbsp; &nbsp; &nbsp; <!--#if-->
&nbsp;&nbsp; &nbsp;<!--#list-->
<!--#if-->
