Threads vB_DataManager_ThreadRate delete issue

[محروم.كوم]

In continue developing of hack the Threads Rating, i was confronted with the problem of class vB_DataManager_ThreadRate.
I wrote this code:
PHP Code:

$threadrate =& datamanager_init('ThreadRate', $vbulletin, ERRTYPE_STANDARD);
$threadrate->set_info('userid', intval($vbulletin->GPC['u']));
$threadrate->set_info('threadid', intval($vbulletin->GPC['t']));
$threadrate->delete();
unset($threadrate);

And I was disappoint by the message
Quote:
Delete SQL condition not specified!
Indeed, this class doesn't have delete functions.
But if i will directly delete data from threadrate table, like
PHP Code:

$vbulletin->db->query_write("
DELETE FROM " . TABLE_PREFIX . "threadrate
WHERE userid = " . intval($vbulletin->GPC['u']) . " AND threadid = " . intval($vbulletin->GPC['t']));

i just delete data from sql, but not from the datastore.

Is it possible to see this function in next version of vebulletin?
And how can i manually delete the information from the datastore?
------------------------------

I think I found the solution.
PHP Code:

$vbulletin->db->query_write("

DELETE FROM " . TABLE_PREFIX . "threadrate
WHERE userid = " . intval($vbulletin->GPC['u']) . " AND threadid = " . intval($vbulletin->GPC['t'])
);

$ratings = $vbulletin->db->query_first("
SELECT
COUNT(*) AS votenum,
SUM(vote) AS votetotal
FROM " . TABLE_PREFIX . "threadrate
WHERE threadid = $threadid
");

$threadman =& datamanager_init('Thread', $vbulletin, ERRTYPE_SILENT, 'threadpost');
$threadman->set_existing($threadinfo);
$threadman->set_info('rebuild', true);
$threadman->set('votenum', $ratings['votenum'], true, false);
$threadman->set('votetotal', intval($ratings['votetotal']), true, false);
$threadman->save();
