Displaying Approved Entries

Displaying Approved Workflow Items
Step 2 of 2

The Guestbook application needs to be updated so that only guestbooks and entries with a status of approved appear in the UI.

Change the getters used to retrieve both entities in the view layer.

1. You need a new import, so first open guestbook-web/src/main/resources/META-INF/resources/init.jsp and add this line:

   <%@ page import="com.liferay.portal.kernel.workflow.WorkflowConstants"%>
   

2. Now open guestbook-web/src/main/resources/META-INF/resources/guestbook/view.jsp. Find the scriptlet that retrieves guestbooks:

   <%
       List<Guestbook> guestbooks = GuestbookLocalServiceUtil
                   .getGuestbooks(scopeGroupId);
           for (int i = 0; i < guestbooks.size(); i++) {
               Guestbook curGuestbook = (Guestbook) guestbooks.get(i);
               String cssClass = StringPool.BLANK;
               if (curGuestbook.getGuestbookId() == guestbookId) {
                   cssClass = "active";
               }
               if (GuestbookPermission.contains(
                   permissionChecker, curGuestbook.getGuestbookId(), "VIEW")) {
   
   %>
   

   Change it so it calls the getter you added that takes workflow status into account. All you need to do is change this method call

   List<Guestbook> guestbooks = GuestbookLocalServiceUtil
               .getGuestbooks(scopeGroupId);
   

   to

   List<Guestbook> guestbooks = GuestbookLocalServiceUtil
               .getGuestbooks(scopeGroupId, WorkflowConstants.STATUS_APPROVED);
   

   Save the file, and now only approved guestbooks are displayed in the Guestbook application.

3. Next, update the entry’s UI in the same view.jsp. Find the tags that set the search container’s total and its results:

   <liferay-ui:search-container total="<%=GuestbookEntryLocalServiceUtil.
                   getGuestbookEntriesCount()%>">
   <liferay-ui:search-container-results results=
                   "<%=GuestbookEntryLocalServiceUtil.getGuestbookEntries
                   (scopeGroupId.longValue(),
                   guestbookId, searchContainer.getStart(),
                   searchContainer.getEnd())%>" />
   

   Replace the getters to use the ones that take workflow status as a parameter, and pass WorkflowConstants.STATUS_APPROVED as the status. Here’s what it looks like when you’re finished:

   <liferay-ui:search-container total="<%=GuestbookEntryLocalServiceUtil.
                   getGuestbookEntriesCount(scopeGroupId.longValue(), 
                   guestbookId, WorkflowConstants.STATUS_APPROVED)%>">
   <liferay-ui:search-container-results results=
                   "<%=GuestbookEntryLocalServiceUtil.getGuestbookEntries(
                   scopeGroupId.longValue(), guestbookId, 
                   WorkflowConstants.STATUS_APPROVED, 
                   searchContainer.getStart(), searchContainer.getEnd())%>" />
   

Now only approved entries are displayed, and the search container’s counter only counts the approved entries. If you update the getGuestbookEntries call but not the getGuestbookEntriesCount call, the count that’s displayed includes approved entries and entries with any other workflow status, and it won’t match the total that’s displayed at the bottom of the search container.

Figure 1: If you don't update the counter method to account for workflow status, it displays an incorrect count in the search container.

Now Guestbooks and Guestbook Entries are now fully workflow enabled, to the great relief of the Lunar Resort’s site administrators. You’ve saved them a lot of headaches dealing with inappropriate content, primarily submitted by visitors from Mars. Those Martians really need some lessons in netiquette.
