Assertion Failed: Cannot find model name error

[CharlieHawker]

I'm having the following error with the inspector when I use it on my (very bare thus far) app. I'm new to Ember so it may be something I'm doing wrong, but given the app is behaving as expected, I'll log it anyway:

Ember Inspector has errored.
This is likely a bug in the inspector itself.

My app at present consists of the following code:

App = Ember.Application.create({
  LOG_TRANSITIONS: true
});
App.ApplicationAdapter = DS.ActiveModelAdapter.extend({
  namespace: 'api/v1'
});
App.TripType = DS.Model.extend({
  title: DS.attr('string')
});
App.ApplicationRoute = Ember.Route.extend({
  setupController: function(controller) {
    controller.set('trip_types', this.store.find('trip_type'));
  }
});
App.ApplicationController = Ember.Controller.extend();

and the template which renders the found trip types is:

<div class="app">
  <header class="app__header">
    <h1>Test</h1>

    {{ view "select"
       content=trip_types
       optionValuePath="content.id"
       optionLabelPath="content.title"
       prompt="Choose a Trip Type" }}
  </header>

  <div class="app__main">
    {{ outlet }}
  </div>

  <footer class="app__footer">
    &copy; Copyright 2015
  </footer>
</div>

As mentioned, API request working successfully and populating the select box, so I'm not sure why I'm getting the error. The error is triggered when I try to select the data tab in the ember inspector.

FYI, using Chrome 43.0.2357.124 on OS X Yosemite 10.10.1 and Ember 1.12.1 with Ember Data as fetched just now via ember-rails gem generator - rails g ember:install.

Unfortunately, As the error says "Please upgrade to Ember.js >= 1.13 for Ember Inspector support", latest Ember Data does not have Ember Inspector support unless you use Ember >= 1.13. (It also requires the latest Ember Inspector which will be released this weekend).

[CharlieHawker]

Ah right, thanks. I did see that and wonder why Ember Inspector was suggesting a beta version of Ember! That answers it, thanks.

[poserr]

So having Ember : 1.13.0-beta.2 and Ember Data : 1.0.0-beta.19.1 won't work before you release latest Ember Inspector? Any workarounds?

[teddyzeenny]

@poserr you could install the Ember Inspector from source.

[jpaas]

I've tried building from source every version back to 1.7.3 and I still get: Assertion Failed: Cannot find model name. Please upgrade to Ember.js >= 1.13 for Ember Inspector support

I can't upgrade to 1.13 yet because it breaks ember-intl. My environment:

@jpaas Ember Inspector 1.8.2 was released, so no need to build from source.

As the error message says, the latest Ember Data (1.0.0-beta.19) requires Ember >= 1.13 to work with the inspector. Your options are to either downgrade Ember Data to <= beta.18, upgrade Ember to 1.13, use ember-cli, or not use the Ember Inspector Data pane until you upgrade Ember.

I didn't realize a downgrade to Ember Data beta 18 would help. That I may be able to do. Thanks @teddyzeenny
