Meteor batch update

Question

I'm using meteor. I'm wondering if theres a shorthand way to do batch updates before the DOM is updated.

for instance I want to update some records,more than one (All at once):

Collection.update(id1,{..})
Collection.update(id2,{..})
Collection.update(id3,{..})

The problem is there are 3 items being updated separately. So when the DOM in my case was being redrawn 3 times instead of once (with all 3 updated records).

Is there a way to hold off the ui updating until all of them are updated?

Answer 1

Mongo's update can modify more than one document at a time. Just give it a selector that matches more than one document, and set the multi option. In your case, that's just a list of IDs, but you can use any selector.

Collection.update({_id: {$in: [id1, id2, id3]}}, {...}, {multi:true});

This will run a single DB update and a single redraw.
