Meteor find using $in with array of Ids
You could rewrite your code this way:
var producerIds = Blocks.find({ "location": location}).map(function (block) { return block.producerId; });var producersList = Producers.find({ "organizationId": user.organizationId, "_id": { "$in": producerIds }}).map(function (obj) { return { "text": obj.name, "id": obj._id };});
Here's a cleaner answer based on Chidrams. Working code example.
var colleagueIds = Posts.find({ type:"colleagues" }).map(function (person) { return person.title; }); //console.log(colleagueIds); return Meteor.users.find({ "_id": { "$in": colleagueIds } });Note that the map function returns the title cursor of my post object. It'll make sense if your a good Wordpress developer. But, you probably want to return the _id of the object.
