RE: Dynamic Menu

[Gavin]

We use an approach where the ACL checks are done in your base SecureScreen
class, which is the superclass for all of your own screen classes.

Using something like:

protected void setContextACLs(AccessControlList acl, Context ctx)
        {
                if (acl == null)
                        return;

                if (acl.hasPermission("admin_users"))
                        ctx.put("Admin", "1");
                if (acl.hasPermission("client_access"))
                        ctx.put("Client", "1");
                if (acl.hasPermission("staff_access"))
                        ctx.put("Staff", "1");
        }


And then in your menu you can simply use this pattern:

#if ($Client || $Staff)
&nbsp;|&nbsp;<a href="$link.setPage("ClientStaffSharedAccess.vm")">Client
and Staff accessible page</a>
#end

#if ($Staff)
&nbsp;|&nbsp;<a href="$link.setPage("StaffOnly.vm")">Staff Only Page</a>

#if ($Admin)
&nbsp;|&nbsp;<a href="$link.setPage("user,FluxUserList.vm")">Users</a>
&nbsp;|&nbsp;<a href="$link.setPage("role,FluxRoleList.vm")">Roles</a>
#end

&nbsp;|&nbsp;<a href="$link.setAction("LogoutUser")">Logout</a>

I don't know how safe it is, but I have used velocity in my Menu.vm to do 
the check, and so far it hasn't broken yet :P


        #if ( $data.getACL().hasRole("sales") )
                d.add(1,0,'Orders' ,'$link.setPage("orders,Status.vm")');
                d.add(2,0,'Customers' );
                d.add(3,0,'Inventory');
                d.add(4,0,'Suppliers' );
        #end

        #if ( $data.getACL().hasRole("administrator") )
        // USERS
            d.add(43, 9, 'Users', '$link.setPage("user,FluxUserList.vm")');
            d.add(44, 9, 'Groups',
'$link.setPage("group,FluxGroupList.vm")');
            d.add(45, 9, 'Roles', '$link.setPage("role,FluxRoleList.vm")');
            d.add(46, 9, 'Permissions',
'$link.setPage("permission,FluxPermissionList.vm")');
        #end


I'm using a javascript tree object so that is what the d.add() methods are 
doing. Depending on the user's roles, they get more and more options added 
to their navigation tree.

If anyone has a better solution I would be interested to hear as well.
