Propel Nested Set in combination with Pagination - pagination

Question

$root = AnimeCommentQuery::create()->findRoot(2);
$html = "<ul>{$root->getComment()}";
foreach ($root->getDescendants() as $post)
{
$html .= '<li style="padding-left: '.$post->getLevel().' em;">';
$html .= $post->getComment();
$html .= ' by '.$post->getIbfMembersRelatedByInsertBy()->getName();
$html .= "</li>";
}
$html .= "</ul>";
echo $html;
I want to paginate the posts but I am not able to do this by:
$root = AnimeCommentQuery::create()->findRoot(2)->paginate(2, 1);
OR
$root = AnimeCommentQuery::create()->paginate(2, 1)->findRoot(2);
Can it be done with standard Pagination from propel? And how?

Answer 1

Don't know if this is too late....
First off, you can't use the paginate and find in the same query, they're both termination methods.
I think what you need is something like this:
$comments = AnimeCommentQuery::create()->inTree(2)->orderByBranch()->paginate(2,1);
Then foreach your way through that Collection.
Now you'll have to be a bit clever with when to close and open lists, checking current Level etc. And top and bottom of page 2+ will take a bit of consideration too. Good Luck!
The Nested Set API is worth studying further http://www.propelorm.org/behaviors/nested-set.html#complete_api, got a fair bit in.
Also consider using a ->joinWith() to get your getIbfMembersRelatedByInsertBy() prepopulated in the main query.
