Freemark in Web Content Template

[Sebastian Wörner, modificado 8 Anos atrás.]

Hi,

i tried to code my own Template for Web Content with freemark.

Its easy to get the fields of the Structure (e.g. ${title.getData()}
But i found no way to get the 'metadata' from the web content, e.g. the create date, the author, the tags and the categories.

In coding a display template with freemark for the asset publisher you iterate over all entries and the entry objects give you access to this metadata.
So, i think, there must be an object to get the metadata in Web Content Template too, or?

Thanks for helping me

Yes there are ways how to get to the data. James F. posted a nice script that shows you what data are stored in the context. Just copy&paste the script in a template.

You'll then see that there are thing like reserved-article-create-date, reserved-article-author-name...

Thanks for sharing this script.
It helps

But i have still two missing meta data
1) expire date
i can get Create Date (${.data_model['reserved-article-create-date'].data}) or Display Date (${.data_model['reserved-article-display-date'].data})
But no way to get the expire date?!

2) Categories
I can access the tag names with ${.data_model['reserved-article-asset-tag-names'].data}
But no way to get the Categories?!

Has anybody a hint for this?

Nobody here, who can help me, to get the two properties?

1) expire date
i can get Create Date (${.data_model['reserved-article-create-date'].data}) or Display Date (${.data_model['reserved-article-display-date'].data})
But no way to get the expire date?!

2) Categories
I can access the tag names with ${.data_model['reserved-article-asset-tag-names'].data}
But no way to get the Categories?!

Thanks

Hi,

You can use the liferay services in VM template if you enable them in the portal-ext.properties.
Here you can find a template witch is getting the article categories:

#set ($groupId = $themeDisplay.getLayout().getGroupId())
#set ($journalArticleLocalService = $serviceLocator.findService("com.liferay.portlet.journal.service.JournalArticleLocalService"))
#set ($ja = $journalArticleLocalService.getArticle( $groupId, $reserved-article-id.data ))
#set ($resourceprimKey = $ja.getResourcePrimKey())
#set ($assetEntryLocalService = $serviceLocator.findService("com.liferay.portlet.asset.service.AssetEntryLocalService"))
#set ($assetEntry = $assetEntryLocalService.getEntry("com.liferay.portlet.journal.model.JournalArticle", $resourceprimKey))
#set ($categoryUtil = $serviceLocator.findService("com.liferay.portlet.asset.service.AssetCategoryLocalService"))
#set ($categoryPorpertyService = $serviceLocator.findService("com.liferay.portlet.asset.service.AssetCategoryPropertyLocalService"))
#set ($assetCategories = $categoryUtil.getAssetEntryAssetCategories($assetEntry.getEntryId()))
#set ($category = $assetCategories.get(0))
#set ($categoryColor = $categoryPorpertyService.getCategoryProperty($category.getCategoryId(),"color"))

#set ($newDate = $dateTool.toDate("EEE, dd MMM yyyy hh:mm:ss Z", $reserved-article-display-date.getData(), $locale))
#set ($formattedDate = $dateTool.format("yyyy. MMMMM dd.", $newDate, $locale))

##The deafult display style is for the article detail page. 
<div class="detail-page-article-content-wrapper"> 	
	<h2 style="color:#$categoryColor.getValue()">
		$!reserved-article-title.data
	</h2>
	<p class="date-publish">$formattedDate</p>
	<div class="detail-page-artcile-content">
		$!Hir_Leiras.getData()
	</div>
	
</div>

from the $assetEntry object you can get the expiration date too.

Zsolt

Yes, Zsolt is right. By the object you can get

When i try to use the serviceLocator:

<#assign assetEntryLocalService = serviceLocator.findService("com.liferay.portlet.asset.service.AssetEntryLocalService")/>

i get this error:
Expression serviceLocator is undefined on line 46, column 35 in 20154#20194#27051.

But the property "freemarker.engine.restricted.variables" is set:


Any Idea why?
Thanks

In Liferay 6.2 there are two properties for each (velocity and freemarker) that manage the restrictions.
For freemarker those would be:

freemarker.engine.restricted.classes=
freemarker.engine.restricted.variables=

You set your variables to freemarker.engine.restricted.variables="" but your still restricting classes. Maybe you should try to change something there in order to get your ftl working.

[Miroslav Ligas, modificado 8 Anos atrás.]

This should disable all the restrictions

velocity.engine.restricted.classes=
velocity.engine.restricted.variables=
freemarker.engine.restricted.classes=
freemarker.engine.restricted.variables=

[Sebastian Wörner, modificado 8 Anos atrás.]

Yes, it works now.

The entries:
velocity.engine.restricted.classes=
velocity.engine.restricted.variables=
freemarker.engine.restricted.classes=
freemarker.engine.restricted.variables

are all empty now.
Now it works :-)
