ampersand-json-patch v1.0.9

ampersand-json-patch

Adds JSON Patch (RFC 6902) support to Ampersand models.

###Don't patch like an idiot.

Usage

npm install --save ampersand-json-patch

ampersand-json-patch is used as a mixin.

var AmpersandModel = require('ampersand-model');
var PatchMixin = require('ampersand-patch-json');

var CarModel = AmpersandModel.extend(PatchMixin, {
	urlRoot: '/api/cars',
	props: {
		id: 'number',
		make: 'string',
		model: 'string',
		year: 'number'
	},
	initialize: function() {
		this.initPatcher();
	}
});

Models now have a patch() method.

var myCar = new CarModel({id: 1, make: 'Honda', model: 'CR-V', year: 1999});

myCar.set({model: 'Civic'});

myCar.patch();

Generates the following HTTP PATCH request to /api/cars/1:

[ { op: 'replace', path: '/model', value: 'Civic' } ]

The patch method also accepts success and error callbacks in the options hash, just like Ampersand's save.

Initializing the patcher with initPatcher({listeners: true}) will fire a patch to the server automatically on every change event to your model.

See JSON-Patch for all supported operations.
