nvm, I got it working. I was confused how async.each() worked..!
here's what I ended up with:
function getMainPost(topics, callback) {
posts.getPostFields(topics.mainPid, ["content"], function (err, data) {
topics.content = data.content;
callback(null);
});
}
function getRecentTopics(category, callback) {
categories.getCategoryTopics(category.cid, 0, parseInt(category.numRecentReplies, 10), uid, function (err, data) {
var topics = data.topics;
category.topics = topics;
category.topic_count = topics.length;
async.each(topics, getMainPost, function (err) {
callback(null);
});
});
}
async.each(categoryData, getRecentTopics, function (err) {
next(err, categoryData);
});
