How can I get repeatable field values of a Liferay Dynamic Data List via API


I try to make a service for reading from Liferay 6.2 DDL.

Here is DDL structure :

<root available-locales="en_US" default-locale="en_US">
    <dynamic-element dataType="string" indexType="text" localizable="false" name="Course_ID" readOnly="false" repeatable="false" required="true" showLabel="true" type="text" width="medium">
        <dynamic-element dataType="boolean" indexType="keyword" localizable="true" name="Active" readOnly="false" repeatable="true" required="false" showLabel="true" type="checkbox" width="">
            <dynamic-element dataType="string" indexType="keyword" localizable="true" multiple="false" name="Language" readOnly="false" repeatable="false" required="false" showLabel="true" type="select" width="">
                <dynamic-element name="option22436" type="option" value="en">

As you can see I have a repeatable checkbox container, who have 3 more element inside structure view

I can get and iterate records list, but no idea how can I get a list with all checkboxes and iterate for their elements inside

DynamicQuery getRecordsetIdQuery = DDLRecordSetLocalServiceUtil.dynamicQuery()
            .setProjection(ProjectionFactoryUtil.distinct(ProjectionFactoryUtil.property("recordSetId")))
            .add(RestrictionsFactoryUtil.ilike("name", courseSetName));

    DynamicQuery getDdlRecordListQuery = DDLRecordLocalServiceUtil.dynamicQuery()
            .add(PropertyFactoryUtil.forName("recordSetId").in(getRecordsetIdQuery));

    JSONArray courseList = JSONFactoryUtil.createJSONArray();

    List ddlRecordList = DDLRecordLocalServiceUtil.dynamicQuery(getDdlRecordListQuery);
    if (ddlRecordList != null && ddlRecordList.size() > 0) {
        int ddlRecordListSize = ddlRecordList.size();
        for (int i = 0; i < ddlRecordListSize; i++) {
            DDLRecord ddlRec = (DDLRecord) ddlRecordList.get(i);
            Field active = ddlRec.getField("Active");

...

Do you can help me with some ideas please ?


Solution

  • I have three fields. solution for how to get repeated Field in portlet.

    1.LanguageName (Parent and Repeated Field) 2. DocumentLinkLabel (Repeated Field) 3. DocumentLink (Child Field)

    for (JournalArticle journalArticle : journalArticleList) {
        Document docxml;
        try {
            docxml = SAXReaderUtil.read(journalArticle.getContent());
            Node root = docxml.getRootElement();
            List<Node> languageList = root.selectNodes("/root/dynamic- 
            element[@name='LanguageName']");    
    
            for (int i = 0; i < languageList.size(); i++)
            {
                Node languageNode = languageList.get(i);
                String languageName =languageNode.selectNodes("/root/dynamic- 
                element[@name='LanguageName']/dynamic-content[@language- 
                id='en_US']").get(i).getText();
                System.out.println("language Name : "+ languageName);
    
                 List<Node> documentLinkLabelList =languageNode.selectNodes("dynamic-element[@name='DocumentLinkLabel']/dynamic-element[@name='DocumentLink']");
                 for (int j = 0; j < documentLinkLabelList.size(); j++) {
                     Node languageNode1 = documentLinkLabelList.get(j);
                     String documentLinkName =languageNode.selectNodes("dynamic- 
                     element[@name='DocumentLinkLabel']/dynamic-content[@language-id='en_US']").get(j).getText();
                     System.out.println(" document Link Lable Name : "+ documentLinkName);
                     String linkNameList=languageNode1.selectNodes("//dynamic- 
                     element[@name='LanguageName']["+(i+1)+"]/dynamic- 
                     element[@name='DocumentLinkLabel']/dynamic-element[@name='DocumentLink']/dynamic-content[@language-id='en_US']").get(j).getText();
                     System.out.println(" linkNameList : "+ linkNameList);
                 }
            }
        } catch (DocumentException e) {
            e.printStackTrace();
        }
    }
