Constraint - Getting current user

[matjazmuhic]

So, here's the thing…

I have implemented custom lucene search based constraint in Java where I used admin:admin to for authentication with AuthenticationService. Now I'm wondering how could I get current logged-in user and check if the user has permissions to read the nodes returned from lucene search.

I tried some things but I think it didn't work cause constraint class is loaded before anyone is logged in so there's no current user. Is it ok to just skip everything until I can get current user?

Can I get current user from my custom constraint or should I implement this using maybe jsf managed bean (just my blind guess) or any other way?

NodeRef person = Application.getCurrentUser(
      FacesContext.getCurrentInstance()).getPerson();
   String username = (String) Repository.getServiceRegistry(
      FacesContext.getCurrentInstance()).getNodeService()
      .getProperty(person, ContentModel.PROP_USER_USERNAME);

   AuthenticationUtil.runAs(new RunAsWork<Boolean>() {

       @Override
       public Boolean doWork() throws Exception {
      return Repository.getServiceRegistry(
         FacesContext.getCurrentInstance())
         .getPermissionService().hasPermission("PUT NODE REF WITHCK YOU ARE CHECKING",
            PermissionService.DELETE);
       }
   }, username);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

hope this helps.

Thank you for the help. But I'm new to this and I'm still wondering if all this (including the constraint) should be implemented in constraint java class or do I implement everything in JSF bean or do I implement constraint in java class and this functionality in jsf bean?

All those options and largeness of alfresco can be overwhelming to a newbie most of the times..



Problem solved. I did that in constraint class. So all the work is done as currently logged in user.
