Find Liferay Journal Atticles By Type and Tag Name

Find Liferay Latest Journal Atticles By Type with Dynamic Query

Here I am sharing with you some knowledge about liferay dynamic query to get journal articles by type.
Actually to get journalArticles list by its type, I was not able to find any service call in liferay, so I have to customized it.

First of all, In Liferay portal.properties which contains Types of Web content. You can override below property and add more customize types from here...

    #
    # Set the list of article types. The display text of each of the article
    # types is set in content/Language.properties.
    #
    journal.article.types=announcements,blogs,general,news,press-release,test

Here I am adding method to get latest articles by its type.

private List<JournalArticle> getArticleByType(long scopeGroupId,
String value) throws PortalException, SystemException {
//maxVersionArticle : Query will find the article with its latest version

 DynamicQuery maxVersionArticle = DynamicQueryFactoryUtil.forClass(
JournalArticle.class, "maxVersionArticle",
PortalClassLoaderUtil.getClassLoader()).add(
PropertyFactoryUtil.forName("articleId").eqProperty(
"articleByType.articleId")).setProjection(
ProjectionFactoryUtil.max("id"));

//articleByType : Query will find the articles by its type and appended the maxVersionArticle query so it will track only latest versions

 DynamicQuery articleByType = DynamicQueryFactoryUtil.forClass(
JournalArticle.class, "articleByType",
PortalClassLoaderUtil.getClassLoader()).add(
PropertyFactoryUtil.forName("id").eq(maxVersionArticle)).add(
PropertyFactoryUtil.forName("groupId").eq(scopeGroupId)).add(
PropertyFactoryUtil.forName("type").eq(value)).addOrder(
OrderFactoryUtil.desc("createDate"));

articleByType.setLimit(0, 5);

LOG.info("Query -- "+articleByType.toString());

List<JournalArticle> ja = (List<JournalArticle>) JournalArticleLocalServiceUtil.dynamicQuery(articleByType);
return ja;

 }

 Find Liferay Latest Journal Atticles By Tag Name

 Here I am adding one more function to get the journal article by tagname

 public List<JournalArticle> getArticleByTags(long groupId, String tagName)
throws PortalException, SystemException {
AssetEntryQuery assetEntryQuery = new AssetEntryQuery();
long[] anyTagIds = AssetTagLocalServiceUtil.getTagIds(groupId,
new String[] { "alllocation", tagName });
assetEntryQuery.setAnyTagIds(anyTagIds);
List<AssetEntry> assetEntryList = AssetEntryLocalServiceUtil
.getEntries(assetEntryQuery);
List<JournalArticle> journalArticleList = new ArrayList<JournalArticle>();
for (AssetEntry ae : assetEntryList) {
JournalArticleResource journalArticleResourceObj = JournalArticleResourceLocalServiceUtil
.getJournalArticleResource(ae.getClassPK());
JournalArticle journalArticleObj = JournalArticleLocalServiceUtil
.getArticle(groupId, journalArticleResourceObj
.getArticleId());
journalArticleList.add(journalArticleObj);
}
return journalArticleList;

}


 Hope this might save your development time!!

Liferay Theme Insight


 
## ---------- Step to Create Theme ---------- ##

Download Theme(template) from http://www.freewebsitetemplates.com/

Create theme
 create myFirstTheme MyFirstTheme;
 or
 You can also use Liferay Developer Studio

Deploy Theme
 ant clean deploy

Note :- below all file create in _diff folder only.

Step :- 1
  •  create css,images and template folder in _diff folder
 Step :- 2
  •  Copy downloaded css files in css folder
  •  create custom.css file in css folder and include all downloaded css files in this file(@import url(style.css);)
  •  Correct image path in all css files(/themeName-theme/images/xys.jpg or ../images/xyz.jpg)
 Step :- 3
  •  Copy all images files in images folder
 Step :- 4
  •  Copy init_custom.vm,portal_normal.vm and navigation.vm files in template folder of _diff from docroot template folder
 Step :- 5
  •  remove body part from  portal_normal.vm and copy body part from index.html to portal_normal.vm
  •  Correct image path in  portal_normal.vm($images_folder/lr-theme.png)

 Step :- 6
  •  Add docbar code imitatively after body tag(<body>)
 #if($is_signed_in)
            #dockbar()
 #end
Step :- 7
  •  Now identify four part in theme(template)
  1.  Static Part
  •   When we are coping body from template to  portal_normal.vm that  time static Contents part will be  covered.
  1.   Navigation Part
  •  There is 1 level,2 level, 3 level are possible in theme
  •  For Navigation part we have to changed  navigation.vm
  •  Create some pages in communities
  •  And add below code in navigation.vm as per your pagination level 
 <ul id="main-nav">
 #foreach ($nav_item in $nav_items)  #if ($nav_item.isSelected())  <li class="current_page_item">  #else  <li>  #end  <!-- Level 1 -->  <span><a href="$nav_item.getURL()" $nav_item.getTarget()> $nav_item.getName()</a></span>   #if ($nav_item.hasChildren())  <ul class="sub-menu">  #foreach ($nav_child in $nav_item.getChildren())  <!-- Level 2 -->  <li><a href="$nav_child.getURL() $nav_child.getTarget()">$nav_child.getName()</a>  #if ($nav_child.hasChildren())  <ul class="sub-menu">  #foreach ($nav_child_second in $nav_child.getChildren())  <!-- Level 3 -->  <li><a href="$nav_child_second.getURL() $nav_child_second.getTarget()">$nav_child_second.getName()</a>  </li>  #end  </ul>  #end  </li>  #end  </ul>  #end  </li>  #end </ul> 
  1.   Main Part(Portlet Part)
  • Now identify your portlet part in theme and add below code for portlet landing.
 #if ($selectable)
            $theme.include($content_include)
             #else
                  $portletDisplay.recycle()
                  $portletDisplay.setTitle($the_title)
                  $theme.wrapPortlet("portlet.vm", $content_include)
 #end

  1.   Footer Part
  •   There is two parts in footer
 1. static 
  •  If footer is static then nothing to do it and its already done when we did copy body from template to  portal_normal.vm
 2. dynamic
  •  If footer is dynamic and its shows some page then again we have do same procedure like navigation.
