Compiled notes on Ember, things to be aware of

Ember Data

  • this.store.find('modelType'); always hits the server, because no ID is given, and there may be new records on the server. Use find in the application route, and all in other places to avoid polling the server every time.
  • this.store.find('modelType', model_id); only hits the server if the model with the given type and ID is not already in the cache.

macu / $children.js
Created March 27, 2014 02:22
Like jQuery's "closest" but for children, depending on a selector that matches the desired parent.
var $container = $(this);
var $children = $this.find('.some-criteria').filter(function() {
return $(this).closest('.my-criteria').is($container);
});

Reopen the Model class, to allow cloning records with overrides.
import Ember from 'ember';
import DS from 'ember-data';
/**
* Returns the model class name, dasherized, which can be used to find
* and create new models of the same type through the store.
*/
export function getClassName(model) {
// typeKey introduced in Ember Data 1.0.0.beta.3
var typeKey = model.constructor.typeKey;
