Query mongodb collection into nested array - node.js

Question

I have a model called List.js that looks like this:
module.exports = function(mongoose, models) {
var collection = 'List',
Schema = mongoose.Schema;
var schema = new Schema({
promotor: String,
nombre_promotor: String,
cod_evento: {type: Schema.Types.ObjectId, ref: 'Evento'},
lista: [{
nombre: String,
cod_usuario_lider: {
type: Schema.Types.ObjectId,
ref: 'Usuario'
},
usuarios_agregados: [{
cod_usuario: {
type: Schema.Types.ObjectId,
ref: 'Usuario'
},
nombre: String,
fbid: String,
tipo_usuario: Number
}]
}]
});
this.model = mongoose.model(collection, schema);
return this;
}
Im trying to find the documents that match with cod_usuario_lider in the field "lista" and the ones that match with "cod_usuario" in "usuarios_agregados" inside "lista". The first part of the query returns the matched documents, but the second part doesnt return nothing. Anyone knows the proper way to do that query?
var codigo_buscar=req.body.codigo_buscar;
models.List.find({
$or: [{
lista: {
$elemMatch: {
cod_usuario_lider: codigo_buscar
}
}
}, {
usuarios_agregados: {
$elemMatch: {
cod_usuario: codigo_buscar
}
}
}]
})
.exec(function(err, data) {
console.log(data);
});

Answer 1

From your document, it looks like usuarios_agregados is an attribute to lista. In that case you have to query as below:
var codigo_buscar=req.body.codigo_buscar;
models.List.find({
$or: [{
lista: {
$elemMatch: {
cod_usuario_lider: codigo_buscar
}
}
}, {
lista.usuarios_agregados: {
$elemMatch: {
cod_usuario: codigo_buscar
}
}
}]
})
.exec(function(err, data) {
console.log(data);
});
