Tags in Velocity Template

[Joona Vaurio，修改在15 年前。]

Hello.

I have a news page, that lists all articles with type news and on the main page I'm supposed to show some of these news. The articles on the main page are not the newest, they are picked manually, so using tags would solve this. However, I can't use asset publisher because the main page news should have a read more link to news page where the whole article is shown in a certain journal content portlet. All this is easy with velocity templates, but I can't figure out how to select the wanted articles to main page. The best way could be using a tag but I did not find any information about that. Is it possible to select articles by tag in journal velocity template?

I'm trying to accomplish the same thing. Were you ever able to figure it out?

I'm also looking for a solution to this?
Any ideas (using Liferay 5.2.3)?

Hi Guys,

I believe the method you're looking for is this:

TagsAssetLocalServiceUtil.getAssets(
	long groupId, long[] classNameIds, long[] entryIds,
	long[] notEntryIds, boolean andOperator,
	boolean excludeZeroViewCount, Date publishDate, Date expirationDate,
	int start, int end)

where entryIds is the entryId of the TagEntry. Then pass the classNameId of journal articles and you should get what you need. (This might not be the exact method parameters, I'm looking at 5.2 ee)

how about in 6.0.5? Haven't founded the way...

What method would we use in 6.0.5?
I have been trying to find it in the javadocs without success.
The only way I could make something similar work was by checking all articles. I'm assuming this would be very bad in terms of performace. If someone know a better way please let me know.
I could select articles by tag in 6.0.5:

#set($AssetTagLocalService = $serviceLocator.findService("com.liferay.portlet.asset.service.AssetTagLocalService"))
#set($JournalArticleLocalService = $serviceLocator.findService("com.liferay.portlet.journal.service.JournalArticleLocalService"))

#set ($searchTag = "TagToSearch")

#set($articles = $JournalArticleLocalService.getStructureArticles(@group_id@,"structure"))
##in my case I know I want the articles that come from a certain structure but it also work with getArticles() in general
#foreach ( $article in $articles)
##check if it is the latest version
 #if ( $JournalArticleLocalService.isLatestVersion(@group_id@,$article.articleId, $article.version))
  ##Check all tags
  #set($articlePK = $article.resourcePrimKey)
  #set ($tagsAsset = $AssetTagLocalService.getTagNames("com.liferay.portlet.journal.model.JournalArticle", $articlePK))
  #foreach( $tag in $tagsAsset )
    #if($tag == $searchTag)
    ##Do whatever, for example
    <p> Render article content: </p>
    <p>uuid: $article.uuid</p>
    <p>Title: $article.title</p>
    <p> ------------------------------------</p>
    #end
  #end
 #end
#end

It has to be a better way

The right way would be to use AssetEntryQuery... but I dont think its possible to instantiate one in velocity...

Heres the Java equivalent for it:

AssetEntryQuery assetEntryQuery = new AssetEntryQuery();
long[] anyTagIds = {tagid};
assetEntryQuery.setAnyTagIds(anyTagIds);
List<assetentry> assetEntryList = AssetEntryLocalServiceUtil.getEntries(assetEntryQuery);
