Class Ember.DataAdapter

public
Extends: EmberObject
Defined in: packages/ember-extension-support/lib/data_adapter.js:14
Module: ember

The DataAdapter helps a data persistence library interface with tools that debug Ember such as the Ember Extension for Chrome and Firefox.

This class will be extended by a persistence library which will override some of the methods with library-specific code.

The methods likely to be overridden are:

  • getFilters
  • detect
  • columnsForType
  • getRecords
  • getRecordColumnValues
  • getRecordKeywords
  • getRecordFilterValues
  • getRecordColor
  • observeRecord

The adapter will need to be registered in the application's container as dataAdapter:main

Example:

Application.initializer({
  name: "data-adapter",

  initialize: function(container, application) {
    application.register('data-adapter:main', DS.DataAdapter);
  }
});
