Programmatically asign Display Page to JournalArticle
New Member Posts: 17 Join Date: 8/25/17 Recent Posts
I'm creating an interface to create JournalArticles with a custom (global) structure. I can't set a default display page for this structure, as it's site dependant.
Trying to figure out how I can set the display page.
I noticed JournalArticle's .getLayout() (on an article with the display page set correctly) seems to represent it (partially at least), but setLayoutUuid() + persist() don't seem to have any effect (at all).

Ideally I'm looking for a method to set a JournalArticle's display page from an url (e.g. a custom setDisplayPage(JournalArticle j, String url) method), though just getting the display page from another - correctly configured - JournalArticle and going from there would be perfectly workable as well (e.g. setDisplayPage(JournalArticle correctly_configured_article, JournalArticle new_article) )

I'm assuming the class AssetDisplayPageEntry will have to be used, but despite all my digging I can't figure it out. Just some pointers in the right direction should be fine, though code snippets are always welcome :-) 

thanks in advance!

Solution:
Adding the correct Layout to the JournalArticle isn't enough.
an AssetDisplayPageEntry needs to be created as well:
JournalArticle article = 

userid = <acquire some userid>
groupid = <acquire relevant site's groupid>
cnameid = PortalUtil.getClassNameId(JournalArticle.class)
context = new ServiceContext()

AssetDisplayPageEntryLocalServiceUtil.addAssetDisplayPageEntry(userid, groupid, cnameid, article.getResourcePrimKey(), AssetDisplayPageConstants.TYPE_SPECIFIC, context)
</acquire></acquire>

Not sure if this helps, but in the Porygon theme we set a default Display Page for a ddm structure. Maybe that can give you some hints.

Look at _addDisplayPageEntry in the PorygonSiteInitializer

LayoutPageTemplateEntry seems specific for Fragment based display pages (I'm using a regular page with default asset publisher); I'll have a look though, might give some new clues, thanks

Got it, maybe I didn't fully understand. Another more classic approach can be found in the PorygonSiteInitializer. Just in case that provides any clues.

I am not sure which version you use, but at least in 7.0 you can set the layoutUuid to the page uuid.

Basically you would write something like (pseudocode)

  Layout layout = layoutlocalservice.getLayout(...);
  String uuid = layout.getLayoutUUID();
  journalarticle.setLayoutUuid(uuid);
  journalarticle.persist();

Tried this already and doesn't seem to have any effect:

(excuse the messy code, just throwing stuff at the groovy tab)

&nbsp; locale = LocaleUtil.getSiteDefault()
&nbsp; group = GroupLocalServiceUtil.search(PortalUtil.getDefaultCompanyId(), null, "Liferay DXP", null, null, false, 0, 1).get(0);

&nbsp;items =JournalArticleLocalServiceUtil.getStructureArticles(group.getGroupId(),"NIEUWS")

&nbsp;item =items.get(5) // &lt;-- article with display page set
&nbsp;jul = items.get(35) // &lt;-- article with display page not set
lay = item.getLayout()

jul.setLayoutUuid(lay.getUuid())
jul.persist()

results in 
Title: Jobevent IT op komst 
getLayout():

Which is the "page" i want (/nieuwsbericht, with default-asset-publisher etc set). No result however:




Unrelated: tried JournalArticleLocalServiceUtil.updateJournalArticle(jul) as well, It won't run however, because jul is of type 'JournalArticleImpl'.. confusing

I think, the answer of Chema is correct, I checked the sourcecode of the JournalPortlet, see _updateAssetDisplayPage:

https://github.com/liferay/liferay-portal/blob/7.2.x/modules/apps/journal/journal-web/src/main/java/com/liferay/journal/web/internal/portlet/JournalPortlet.java

Btw.: Good to know that this has changed. I think we did something similar as you do. JournalArticleLocalServiceWrapper + "fix" the displaypage for news entries. And some day in the future, we will migrate that to 7.2 or so ...
