ampersand-collection-rest-mixin

Part of the Ampersand.js toolkit for building clientside applications.

A mixin for extending ampersand-collection with restful methods. To make it behave much like Backbone.

install

npm install ampersand-collection-rest-mixin

api

create(model, options)

Create a new instance of a model in this collection. Add the model to the collection immediately.

options

• wait - default: false. If set to true, we wait for the server to agree before updating the collection.

fetch(options)

Fetch the default set of models for this collection, and set them onto this collection.

options

• reset [boolean] - default: false. Executes the reset method on the collection with server response instead of the set method.
• set [boolean] - defaut: true. When left true, executes the reset method on the collection with server response. When set to false, the collection will not be modified after the HTTP request is complete. This enables use of of the collection strictly as an API client. The success and error handlers are still triggered. Useful in rare circumstances.
• success(collection, response, options) [function] - default: undefined. Called after the XHR has completed successfully and the collection is updated.
• error(model, response, options) [function] - default: undefined. Called after the XHR has failed.
• always(err, response, body) [function] - default: undefined. Called when request finishes no matter what the result.

fetchById(id, options, cb)

fetches a model and adds it to collection when fetched

getOrFetch(id, options, cb)

get or fetch a model by id

options

same options as fetch(), with the addition of:

• all [boolean] - default: false. If true, this fetches the entire collection and then returns the requested model.

sync()

proxy to ampersand-sync

example

var Collection = require('ampersand-collection');
var restMixin = require('ampersand-collection-rest-mixin');


module.exports = Collection.extend(restMixin, {
    sampleMethod: function () {
        // now we've got restful methods in our collection
        this.sync( ... );
        this.fetch( ... );
        this.create( ... )
    }
});
