How it works
import Realm from 'realm';
import RealmModel from 'react-native-realm-model';
const realm = new Realm({
schema: [{
name: 'Product',
properties: {
title: 'string',
content: {
type: 'string',
optional: true
},
price: 'int'
}
}]
})
class Product extends RealmModel {
static realm = realm;
// custom methods
priceLabel() {
return this.price + 'vnđ';
}
}
Product.insert({title: 'Product 1', content: 'This is content', price: 22000});
var product = Product.findOne();
console.log(product.priceLabel());
product.update({price: 24000})
console.log(product.priceLabel());
product.remove();
