"Publish Version" Hook Plugin
Publish Version Hook Plugin
Thiss article is described about the Custom Publish Version hook which is available in Community plugins. Using this hook, we can revert back old version of journal aticle easily.
The Journal portlet provides a user interface to the admin or content owner to add , edit , delete ,expire the articles and displaying all the versions of article.
All versions will be displayed in the list of available Journal Articles as shown below:
(Edit Article --> View History)
A new version will be generated automatically if article is modified
Managing version is having some limitations in Liferay that users cannot publish the old version of the article. If user s want to publish the old version, they should expire all the versions of the article which we cannot revert back once done.
eg., a article has more than 100 versions since it has been modified for 100 times, but user wants to re-publish 1.1 version which is initial version of the article. Then, they have to expire all 99 versions [ 1.2 to 1.100 ] which is hectic and not safe for expiring all the articles in a huge content management portal as anytime we may need to revert back some version of the article.
Publish Version Hook
I have developed struts action Hook plugin by customizing jsp(s) and action files of the journal article for publishing any version of the article.
This PublishVersion-Hook plugin helps article’s admin or content owner to re-publish the article without expiring the old versions. User cannot publish the Multi Articles or Expired article and Latest version.
Use Cases :
- Update the Article through web content display portlet or control panel.
2. A new version will be generated automatically if article is modified each time.
3. Click View History section where all the version of the articles will be displayed as shown below
4. Select old version of the article and click Publish.
5. You cannot publish Latest / Expired / Multiple articles at a time .
I have developed this plug-in in Struts Action Hook. Reason for developing Struts Action Hook is, I was planning to learn Struts Action Hook for long time since this new feature introduced. So, finally done it. J
I have overridden the existing Struts Action /journal/edit_article which extends BaseStrutsPortletAction and In View History Page [view_article_history.jsp & article_version_action.jsp], new Publish buttons are added to publish the selected version.
When publishing the selected version, it is redirecting to Custom Struts Action class where I have written my logic to change the selected version’s count as latest version by increasing 1 with latest version. So automatically latest version will be displayed.
JournalArticle selectedVersionObject = JournalArticleLocalServiceUtil.getArticle(selectedId);
selectedVersionObject.setVersion(MathUtil.format(lVersion + 0.1, 1, 1)); //increasing 1 with latest version
