Why my collection.find() does not work in meteor but work in robomongo?

Question

I have a publication that should return me all users matching an _id array. here it the query:

Meteor.users.find({
            \'_id\': { $in: myArr         


        

Answer 1

It looks like you are trying to specify fields in your find, which you can do like this:

var options = {
  fields: {
    'profile.name': 1,
    'profile.description': 1,
    'profile.picture': 1,
    'profile.website': 1,
    'profile.country': 1
  }
};

Meteor.users.find({_id: {$in: myArray}}, options);

However, if this is being used in a publish function, I strongly recommend using only top-level fields like so:

Meteor.users.find({_id: {$in: myArray}}, {fields: {profile: 1}});

For more details on why, please see this question.

For your second question, you can view the documents returned by a cursor by calling fetch on it. For example:

console.log(Posts.find({_id: {$in: postIds}}).fetch());
