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

But their selected answers are no more applicable for Ember 2.x. Those questions are: 1, 2. 回答1: I´m not sure if queryparams won´t work with arrays as I only used it with single ids, but it
