Find object by realm.js

Question

Hello I use realm database with react-native.

I have Item schema and find one item by id.

var items = realm.objects('Item');
var item = items.filtered('id == $0', item_id);
console.log(item.name); // It should be printed name, but undefined

I can't find item. so use lodash.

var item = _.find(realm.objects('Item'), _.matchesProperty('id', item_id));
console.log(item.name); // print "ABCD"

How do I get item by id?

Answer 1

filtered returns a Results object which is very similar to a javascript Array.

So your code should be:

var items = realm.objects('Item').filtered('id == $0', item_id);
var item = items[0];
console.log(item.name); // should print the name

Answer 2

realm.objectForPrimaryKey('Item', item_id)
