Hi!
Alexey Kakunin:
Copied from EmForge Portal forum (
http://www.emforge.net/web/emforge-portal/forums/-/message_boards/message/178629)
Finally, I get the job done, the JSP was able to be called from the view.jsp, I have to inherited the JSPPortlet, that is the key.
But, still, I have couple of more questions.
1. from view.jsp, I like to add the pet_action.jsp, and it contain two icons, one for edit, another one for delete, but it didn't work, from pet_action.jsp, I add the JSP for pet_edit.jsp, inside the pet_edit.jsp, I use the follow code
1ResultRow row = (ResultRow)request.getAttribute(WebKeys.SEARCH_CONTAINER_RESULT_ROW);
2Pet pet = (Pet)row.getObject();
Looks a little bit strange why you need it in pet_edit.jsp
Actually, to add actions into each row with pet you need to do on view.jsp something like:
1
2List<ResultRow> resultRows = searchContainer.getResultRows();
3 for (int i=0; i < pets.size(); i++) {
4 Item pet = pets.get(i);
5 ResultRow row = new ResultRow(pet, pet.getItemId(), i);
6
7 PortletURL petURL = renderResponse.createRenderURL();
8 petURL.setWindowState(WindowState.MAXIMIZED);
9 petURL.setParameter("pet_id", String.valueOf(pet.getItemId()));
10 petURL.setParameter("redirect", com.liferay.portal.util.PortalUtil.getCurrentURL(request));
11 row.addText(pet.getName(), petURL.toString());
12
13
14 row.addJSP("/pet_image.jsp", application, request, response);
15 row.addText(String.valueOf(pet.getPrice()));
16
17 row.addJSP("/pet_action.jsp", application, request, response);
18
19 resultRows.add(row);
20 }
(Don't forget to add one more column into headers of table)
and in pet_actions.jsp some code like
1 2<%@ page import="com.liferay.portal.kernel.dao.search.ResultRow" %>
3<%@ page import="com.liferay.portal.kernel.util.WebKeys" %>
4<%@ page import="petcatalog.model.Item" %>
5 6<%
7ResultRow row = (ResultRow)request.getAttribute(WebKeys.SEARCH_CONTAINER_RESULT_ROW);
8 9Item pet = (Item)row.getObject();
10String petId = String.valueOf(pet.getItemId());
11%>
1213<portlet:renderURL var="editURL">
14 <portlet:param name="jspPage" value="/pet_edit.jsp" />
15 <portlet:param name="redirect" value="<%= currentURL %>" />
16 <portlet:param name="petid" value="<%= petId %>" />
17</portlet:renderURL>
1819<liferay-ui:icon image="edit" url="<%= editURL %>" />
2021<portlet:actionURL name="deletePetItem" var="deleteURL">
22 <portlet:param name="redirect" value="<%= currentURL %>" />
23 <portlet:param name="petid" value="<%= petid %>" />
24</portlet:actionURL>
2526<liferay-ui:icon image="delete" url="<%= deleteURL %>" />
This code should also answer how to add edit/delete buttons, as well as how to pass petid into pet_edit.jsp
To delete pet you will need to add action method into PetPortlet like:
1
2 public void deletePetItem(ActionRequest request, ActionResponse response) throws Exception {
3 Long petId = ParamUtil.getLong(request, "petId");
4
5 // code to remove pet
6
7 }
Alexey Kakunin:
but the second line throw the exception, is that means this can not be called from pet_edit.jsp
2. I like to add the edit and delete icon for each pet, where I can find the hint for the code, I like to use liferay UI tag as much as possible, so it can fit in the main theme.
Alexey Kakunin:
3. still, from doView class, follow the code, I can not get the right petid, it always return 0, which is kind of surprise.
I am eager to see the second part of this tutorial, this is one of the best liferay portal tutorial I can find, hope it can keep it update.
Thanks.
Unfortunatelly too busy, but I hope to update tutorial to follow Liferay 6 and Liferay IDE soon, as well as extend it (for example cover these questions about actions)
