Ember.js: Route Recognizer - Add route name in error message when missing params

[eomeri]

As a developer when I try to transition using the controller.transitionToRoute('routeName', model) method, I get an error thrown in the console with no indication of the route name. It appears that in my case when I request a transition to 'customer', it intends to redirect into the 'customer.index' sub-route and it is missing a parameter.

It would be nice to have the route name shown in the error.

ember-metal.js:3992 Error: You must provide param customer_id to generate.

@eomeri Since the issue tracker is mostly for bugs, and we use the RFC's repo for proposed changes, this issue may get more responses as an RFC issue (not a full proposal, just a simple issue like this one but instead moved to the RFC repo).

• https://github.com/emberjs/ember.js/blob/master/CONTRIBUTING.md#requesting-a-feature

Use RFC issues to propose a rough idea, basically a great place to test the waters

@eomeri did you post an issue on the ember-rfc's repo? https://github.com/emberjs/rfcs/issues

Thanks for your help

Totally agree that this experience sucks, sorry about that. The error message should absolutely include the route name in addition to the query param provided.

IMHO, bad error messages are bugs, so I'm going to go ahead and label as such...
