how to exclude array type fields with mongoose

Question

I have a schema like this:

var CitySchema   = new Schema({
    name: {type : String, required : true},
    region: {type: Schema.Types.ObjectId, ref: 'Region', required : true},
    images: [{type : Schema.Types.ObjectId, ref: 'Image', select: false}]
});

When I do query on the collection, the field images would still show up even when I put the select: false. How can I hide the field without using .select('-images')?

City.find({}).sort('name').lean().exec(function(err, cities) { console.log(cities); }); — Oscar Yuandinata

Have you tried City.find({}, 'name region').sort('name').lean().exec(function(err, cities) { console.log(cities); })? — chridam

When you are putting select: false, you say to exclude values inside the images array. You need to put select: false for the images array itself.

Look at this stackoverflow post.

Applied to your case:

var CitySchema   = new Schema({
    name: {type : String, required : true},
    region: {type: Schema.Types.ObjectId, ref: 'Region', required : true},
    images: { 
      type: [{type : Schema.Types.ObjectId, ref: 'Image', select: false}],
      select: false, 
    },
});
