RealmModel is a wrapper for realm.

CHANGELOG

• 0.0.10

  • Fixed some bugs

  • Supported model events: beforeInsert, afterInsert, beforeUpdate, afterUpdate, beforeRemove, afterRemove

    class Product extends RealmModel {
    static realm = realm;
    
    static beforeInsert(doc) {
        doc.createdAt = doc.updatedAt = new Date();
        return doc;
    }
    }

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();

API

find(selector: Object, option: Object) -> Array

• selector is search criteria

  • Type 1: {field: value}
  • Type 2: logical operator {$or: [{field1: value1, field2: value2}]}

  • Type 3: realm operator ==, >=, <=, >, <, BEGINSWITH, ENDSWITH, CONTAINS and string comparisons can be made case insensitive by appending [c] to the operator: ==[c], BEGINSWITH[c] etc.

    Ex: Product.find({title: {'BEGINSWITH[c]': 'hello'}})

• option is search option support: limit, offset, sort

findOne(selector: Object)

insert(data: Object)

update(selector: Object, modifier: Object)

remove(selector: Object)
