Adding Page Template in liferay Programmatically

We know that we can create the page template from the control panel, What if we want to create programmatically. So here we go,

1. We are reterving the page template name form the portlet.properties. If you want to know how to create the portlet.properties and retrieve follow the below link.

http://liferaytutorial.blogspot.in/2013/03/how-to-read-values-from-properties-file.html

So here i am retrieving the page template name as page.template from portlet.properties file.

String pageTemplateNames = PortletProps.get("page.template");


In Portlet. properties

page.template = Home,Test



Before adding the page template we are checking weather page template exists or not by dynamicQuery , because we don't have any finder method to check the page template by name. Here i am checking by descrition beacause name will be storing as JSON format in DB.

List<LayoutPrototype> layoutProtoTypeList = null;
DynamicQuery dynamicQuery = DynamicQueryFactoryUtil.forClass(LayoutPrototype.class);
dynamicQuery.add(RestrictionsFactoryUtil.eq("description", pageTemplate+"description"));

try {
layoutProtoTypeList = LayoutPrototypeLocalServiceUtil.dynamicQuery(dynamicQuery);
} catch (SystemException e) {
e.printStackTrace();
}



Also Page template name supports mulitilingual so here we are storing the name with JSON format as language id also,

public Map getLocalizationMap(Locale siteLocale, String value) {

Locale[] locales = LanguageUtil.getAvailableLocales();

Map map = new HashMap();

for (Locale locale : locales) {

if(locale.equals(siteLocale)) {
map.put(locale,value);

} else {
map.put(locale,StringPool.BLANK);
}

}

return map;
}



Here is the full code as ,

List<LayoutPrototype> layoutProtoTypeList = null;

String pageTemplateNames = PortletProps.get("page.template");
String pageTemplates [] = StringUtil.split(pageTemplateNames, ",");

for(String pageTemplate : pageTemplates) {

DynamicQuery dynamicQuery = DynamicQueryFactoryUtil.forClass(LayoutPrototype.class);
dynamicQuery.add(RestrictionsFactoryUtil.eq("description", pageTemplate+"description"));

try {
layoutProtoTypeList = LayoutPrototypeLocalServiceUtil.dynamicQuery(dynamicQuery);
} catch (SystemException e) {
e.printStackTrace();
}


if(Validator.isNotNull(layoutProtoTypeList) && layoutProtoTypeList.isEmpty()) {

boolean active = true;
String description = pageTemplate+"description";

Map nameMap = null;
Locale siteLocale = themeDisplay.getLocale();
nameMap = getLocalizationMap(siteLocale,pageTemplate);

ServiceContext serviceContext = null;
try {
serviceContext = ServiceContextFactory.getInstance(request);
} catch (PortalException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}


try {
LayoutPrototypeLocalServiceUtil.addLayoutPrototype(themeDisplay.getUserId(), themeDisplay.getCompanyId(), nameMap, description, active,
serviceContext);
} catch (PortalException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}


}
}
