Meteor - collection.find() always returns all fields

Solution 1:

your syntax is off a bit, it should be

CollectionName.find({}, {fields: {'onlyThisField':1}});

or

CollectionName.find({}, {fields: {'everythingButThisField':0}});

your template does indeed control what data is displayed, but there are still many scenarios where field limiting makes sense - privacy of data or efficiency (some fields of all records, all fields of the 'current' record) are two common ones

you didnt mention it, but this usually is within a publish function - see http://docs.meteor.com/#meteor_publish - the fields modifier is also available on the client, but there it does not limit data sent down to client, just to the template - server side field reduction/selection has different benefits

double check that you've removed the autopublish package too, however you should see a warning if you have that active and write your own publish functions, which is where you would most commonly use fields

Solution 2:

First, if you want to control some fields in Collection.find()，you can try to do it this way:

CollectionName.find({}, {fields: {field:1}});

but it was working only on the server.

Or try this:

On the server:

Meteor.publish("myCollection", function () {
    return SvseTree.find({},{fields: {field:1}});
});

On the client:

Meteor.subscribe("myCollection");

then run meteor remove autopublish.

Second, if you want to get Array of Collection.find(), try to do it: Collection.find().fetch();
