How to assign Permissions to site page dynamically when created

Question

In Liferay when a site page is added, it is assigned VIEW permission automatically for Owner role, Guest role and Site Member role.

Is it possible to assign VIEW permissions dynamically to custom role when page is created instead of manually assigning VIEW permission from Manage-permission tab of the site-page?

Answer 1

One of the possible way is Using LayoutListener via hook

For this you need to create hook (portal properties) and override following property:

value.object.listener.com.liferay.portal.model.Layout

See the following example:

value.object.listener.com.liferay.portal.model.Layout=com.smb.mypermissions.hook.listeners.LayoutListener

Here LayoutListener is the custom class created under package com.smb.mypermissions.hook.listeners to override default LayoutListener.

Signature for this class: public class LayoutListener extends BaseModelListener<Layout>

Now override the method

public void onAfterCreate(Layout model)throws ModelListenerException

to assign permission to the role, use following one liner:

ResourcePermissionLocalServiceUtil.setResourcePermissions(
    companyId, Layout.class.getName(),
    ResourceConstants.SCOPE_INDIVIDUAL,
    String.valueOf(primKey), role.getRoleId(),
    new String[] {
        ActionKeys.VIEW
    });

where role can be obtained from RoleLocalServiceUtil and primkey is the page unique id i.e plid

long primKey = model.getPlid();

long companyId = model.getGroup().getCompanyId();

Role role = RoleLocalServiceUtil.fetchRole(companyId, "<Your Role name here>");
