问题 In Ember 2+, does anyone know how to get a reference to the Ember Store in order to troubleshoot Model mapping in the javascript console? It was possible through App.__container__.lookup in Ember 1, but this doesn't exist anymore, and it's bloody hard to find documentation on this. Thanks 回答1: If you look in your package.json , you should see a ember-export-application-global package that's installed by default (if not, install it). This will export your application not to the global App

问题 Is it possible to pass parameters like this? I need to pass some information that is not part of the model itself. myModel.save({site : 23}) 回答1: It is possible if you: add a 'volatile' attribute to your model, define a custom model serializer, and override its serializeIntoHash method. For instance: App.Model = DS.Model.extend({ //... site: DS.attr('number', { serialize: false }) }); App.ModelSerializer = DS.RESTSerializer.extend({ serializeIntoHash: function(hash, type, record, options) {
